More detailed information' is given in .the .'!Saline Water. Conversion.Report •for 1958" of the Director of the.Office of Saline Water. Recognizing the urgency of augmenting the .supply-of.fresh water to meet the demands of the expanding population, industry, and agriculture of the United States, Congress enacted S - J. Res•: 135, which became Public Law.85.-883, _on September 2, 1958.- This new legislation authorizes the construction and -operation of not less than.five demonstration plants to test several of .the more advanced' saline water conversion processes: The measure', - as' amended and-,reported -to-:the House, and.as .it was finally enacted, was sup- ported.by the Department. The demonstration plant program will complement the present. program,and .will be -administered by -the Office of Saline_ Water. Continued emphasis will be placed on the research and development. work in order...to. assure orderly .progress toward practical and' economical saline water conversion..-..- Ten million dollars was authorized for -the -construction of the five -demonstration plants plus such additional sums. a.s will be required' for their -operation: Three are to be sea-.wa.ter plants and are- to be located on the west coast; east coast.; 'and gulf coast. Capacity of at .least two of. these ,plants is to be not less than one million gallons per .day of fresh water. The remaining. two plants are for brackish water conversion. One ,is to be located in the Northern Great Plains and,one in..Ahe,:Southwest.. The capacity .of at least one of these.plants. shall be not less than 250,000°,gallons per day.' I.plan to.select the :first:process to be tested on or before '. March 2, 1959. The remaining four processes will be selected at three month intervals thereafter. Site selection for each of the 1 plants will follow and be dependent on the process chosen. Civic bodies, public officials, industrial development agencies, and private individuals have requested that plants be located in their particular areas. Such requests have been received from Arizona., California, Connecticut, Florida, Kansas, Louisiana, Maryland, Massachusetts, Mississippi, Nebraska, New Hampshire, New Jersey, New Mexico, New York, North and South Dakota, Oklahoma, Rhode Island, Texas, Virginia, and Washington. A prospectus outlining six principal conditions that will be considered in reaching a. final decision on location, size, and type of plant has been prepared for use of those who wish to provide such information to support their petition. Agreements with states providing for cooperation and'partici- pation in the research and development .a.ctivities, as well-as in the demonstration plant program -are under negotiation.- Cooperative . agreements have already been executed with California. and New Mexico. The regular budget estimate for -.Fiscal Year 1959 -for.-$825,000 was submitted and appropriated. Subsequently, as a result of recommendations made by the Secretary's Advisors-on' Saline Water Conversion, the Department requested an' additional $530)000, of which $345,000 was appropriated by the- Congress. The-budget reflects the accelerated pilot plant development begun last year and supplemented by additional funds- in -April. Funds will also be expended for addi- tional basic research and for development of existing processes that show promise. Activities during the -yeas included both the initiation of ' additional research and development work and pilot-plant activities. In the pilot plant phase, test work was continued with good results on a Badger long-tube-vertical evaporator cycle and the Hickman rotary distillation equipment. Additional research is being carried out on- a smaller rotary unit. A pilot plant program on solar distillation was initiated near Fort Orange, Florida. A 15,000 gallon per day pilot plant using freezing as a. separation process is being constructed by the Carrier,Corpora.tion of Syracuse, New York. The pilot plant!as based upon successful laboratory research and development carried out by Carrier under a. previous contract. . A preliminary study and functional design of'a multi_stage, flash; saline water conversion plant -that may be adaptable for "use with nuclear heat, is being carried out by the Fluor Corporation of Whittier, California, as a part of the cooperative program with the State of California.. The State is sharing. the" cost of this; research and develop- . went work. _ A program designed to develop improved large-capacity electro- chialysis processes principally for use on brackish water was initiated et the. Bureau of Reclamation Laboratories, Denver, Colorado. A Netherlands T.N.O. electrodialysis unit was purchased and will be operated in addition to the Ionics, Inc., unit developed in the United' 2 States. The research on reverse osmosis and the osmionic process together with that on the solvent extraction process has been continued with good results. The first pha.se in research involving the use of algae to deminera.lize saline water was completed successfully and a second phase initiated. Several other exploratory and basic research studies have been continued. A far reaching importance of this program demands that we constantly study and evaluate the procedures and developments of the Office of Saline Water. An independent board of consultants., expert in initiating and directing scientific research programs, was appointed to study the organization and procedures of the Office of Saline Water. This board has made a number of recommendations regarding future operations, which are being given consideration at this time. A review of the entire saline water program, made by the House Committee on Government Operations, resulted in a number of constructive suggestions for augmenting and improving the program. Many of these suggestions are being put into effect as rapidly as possible. Several industrial and commercial concerns, and at least one municipality are already utilizing converted sea. or brackish water. Continued reduction of conversion costs will permit us to obtain much of our water from the oceans in the foreseeable future, with 22 of our states bordering on the coast containing 65% of our industry and 55% of our population, the impact and importance of this program to the future of our country is unmistakably clear. With warm regards, I am Faithfully yours, Secretary of the Interior The President The White House Washington, D. C. Identical letters to: President of the Senate Speaker of the House 3 FOREWORD This annual report of progress in saline water conversion during 1958 contains information on developments during the past year only. If more background is desired, the reader may wish to refer to the more detailed discussions contained in the report for 1957, which summarized the work since 1952. During 1958 a considerable part of the activities of the Office of Saline Water was devoted to compiling and supplying data needed for various reviews and evaluations of the program, including extensive leg- islative activity. A total of seven Congressional hearings were held on various aspects of the work; the program was reviewed and evaluated by the Advisory Committee in March; and by a select board during September - November. The Coordination Table appended to this report lists all known current research and development work in the field of Saline Water, including both that sponsored by the Department of the Interior and that sponsored by others. Information on any work not included in this table would be welcome.

Othmer, Brooklyn Exchange Surfaces Polytechnic Institute Multi-stage Flash Distillation With Fluor Corporation and Without Use of Nuclear Process Heat Fundamental Research in Scale University of Michigan Deposition and Prevention Research Institute Long-Tube-Vertical Multiple Effect Distillation. A long-tube-vertical (LTV) test facility at the International Nickel Company Test Station, Wrightsville Beach, North Carolina, which was erected in November 1957, has permitted experimentation during the past year over a wide range of vari- ables which would be found in a multiple-effect sea-water plant. It has been used not only to provide data for a large sea-water distillation plant but also to study various scale-prevention techniques, and is adapted also for use in determining the corrosive effects of sea water. The test program is being carried out by the Whiting Corporation and W. L. Badger and Associates, Inc., under a contract with the Office of Saline Water. • The objective of the contract is to reduce the cost of saline water .conversion by the use of long-vertical-tube, multiple-effect evaporators using proposed techniques that will prevent scale and control corrosion. The test facility consists of two forced circulation (FC) evaporators 1 J connected to a small long-vertical-tube evaporator. The FC evaporators are used to concentrate the sea water to any desired concentration and to pre- pare the sludge for the scale-control tests. The experimental work is carried out in the long vertical tube evaporator consisting of seven 2-inch-diameter tubes, each 24 feet long, in a single shell. The seven tubes are of different materials to provide comparative corrosion studies. The test facility is designed so that the residence time of the feed water in the evaporators is of the order of a minute or two so that the advantages of high-velocity feed water for both heat transfer and anti-scaling effects ' can be determined. The facility is equipped with a filtering section to be used in the sludge tests, since it is necessary to extract the sludge from the blowdown for reuse in the system. Heat transfer data have been obtained for both rising and falling film conditions over a range of temperatures that would be met in practice. Two methods have been worked out for controlling calcium-carbonate scale. The first requires the use of acid to prevent scale. This has been successful and proper pH control has been worked out to prevent corrosive conditions from developing in the evaporator. The second method requires the use of a calcium-carbonate sludge. The theory of this method is that calcium carbonate in solution that is on the verge of precipitating from the sea- water feed will deposit upon its own kind rather than upon the metallic surface of the evaporator tubes. This method is known as the "internal stabilization techniquell and has been successfully used for the control of both calcium-carbonate and magnesium-hydroxide scales. Exploratory work for the control of calcium-sulphate scale in the LTV evaporator by this method is under investigation. Some corrosion information has been obtained from the many experimental tests made during the past year, but at least one continuous 1,000-hour test will be required before the method of controlling corrosion, proposed by Badger, can be confirmed. Large Rotary Vapor Compression Distillation. Two vapor-compression, rotary-distillation units known as the No. 4 and the No. 5 Hickman Stills were manufactured and tested by the Badger Manufacturing Company of Cambridge, Massachusetts, under an earlier contract with the Office of Saline Water. At the conclusion of that contract, the No. 4 Still, a single-rotor unit, was shipped to the laboratory of the Battelle Memorial Institute in Columbus, Ohio, for further research and 'development. The No. 5 Still, a multi-rotor unit, was shipped to Wrightsville Beach, North Carolina, and is located on the premises of the International Nickel Company Marine Test Station. Battelle Memorial Institute is conducting the program to test the unit on natural sea water. The objectives of the contract with the Battelle Memorial Institute are to further develop the potentialities of the Hickman rotary, vapor- compression still. During the past year many important parameters have been investigated and the basic factors affecting the improvement of the Hickman process are better known. Research on the No. 4 Still has shown that a distribution of the sea water on the rapidly rotating heat transfer surface could be improved and work is under way on this problem. The 2 solution of this problem will provide valuable information on the phenomenon of ebullition from a moving surface and will determine the future designs of the Hickman still. The field work with the No. 5 Still has shown that not only scale, but more particularly erosion and corrosion, are problems which require further investigation. Other factors such as mechanical and process reliability, maintenance, and operational requirements have been evaluated. Dr. K. C. D. Hickman, the inventor of the rotary still, has been retained as a consultant to the Office of Saline Water on the continuing program for the investigation of the Hickman process. Two reports describ- ing the work on the Hickman stills have been published by the Office of Saline Water. Small Rotary Stills. The Denver Laboratories of the Bureau of Reclamation completed their drawings and specifications during 1958 for a small rotary vapor-compression still, based on a conception of Mr. R. E. Glover of the Laboratories and a contract for its fabrication was awarded to The Mechanical Equipment Company of New Orleans, Louisiana. In this type of rotary still it is proposed to incorporate the blower into the spinning disc arrangement in order to eliminate the need. for a separate compressor. A number of rotors could be mounted on the same shaft and rotated in a common chamber without departing from the spirit of the suggested improvement. A patent on the Glover system has been applied for. Forced-Circulation Vapor Compression Stills. The economic evaluation of saline water conversion by means of forced-circulation vapor-compression distillation was performed under a contract with B. F. Dodge (Yale Univer- sity) and A. M. Eshaya. The objective of the contract was to determine whether further work on the forced-circulation and dropwise-condensation vapor-compression evaporator is desirable. This process is a vapor- compression cycle in which the brine is in forced circulation within the tubes and the steam condenses in a dropwise manner on the outside of the tubes. A study has been made to determine the optimum combination of the important variables. Dodge and Eshaya found that experimental and theoretical evidence supports the view that dropwise condensation and forced circulation will result in increasing the over-all heat-transfer coefficient in industrial distillation equipment by a factor of .three to four over coefficients in present-day equipment. Forced circulation is expected to bring about an additional improvement by retarding and possibly eliminating scale formation. A further improvement in this direction may be expected from flashing the liquid in a separate chamber and not in the heat exchanger. A cycle incorporating forced circulation, dropwise con- densation, and the use of a flash chamber has been investigated and the optimum combination of the important variables for such a cycle have been determined. Cost estimates were prepared to indicate the possible promise of the proposed cycle. Dodge and Eshaya conclude that intensive research and development to develop forced-circulation dropwise-condensation techniques is justified based on results to date. A Progress Report has been published by the Office of Saline Water covering the work under the contract. 3 Feasibility Studies of a Saline Water Distillation System Without Heat Exchange Surfaces. A small study was initiated by the Office of Saline Water in order to analyze the technical feasibility of developing a saline water distillation system without metallic heat exchange or phase barriers. The development of such a system might enable reductions in capital and maintenance costs while at the same time permitting the attainment of high thermal efficiencies. Both Dr. D. F. Othmer and Food Machinery & Chemical Corporation independently conceived and proposed the suggested evaporator cycle to the Office of Saline Water. In addition, the Corporation suggested the use of a liquid-liquid-liquid heat exchanger as an integral part of the proposed system. Therefore complementary feasibility studies were contracted for with both Dr. Othmer and Food Machinery & Chemical Corporation. Initially Dr. Othmer is concentrating on a comprehensive theoretical analysis of the operating variables of the "vapor reheat flash evaporation system". The Corporation is concentrating on the heat exchanger aspects of this system with both contractors keeping each other closely advised. If the system is determined potentially practical, small-scale experiments on laboratory equipment will commence early in 1959. Multistage Flash Distillation With and Without Use of Nuclear Process Heat. During 1958 the Fluor Corporation, Whittier, California, completed an initial feasibility study of the economic and technical possibilities for combining process steam nuclear reactors with selected evaporator systems. The Reactor Development Division of the Atomic Energy Commission provided consultant assistance on the nuclear aspects of the investigation. The results of the first year of study were published as Office of Saline Water Research and Development Progress Report No. 19. This report concludes that both light-water and heavy-water reactors, if developed for this particular application, show promise of producing steam at reasonable cost, and that both the long-tube-vertical multiple-effect and flash multi- stage systems, or combinations of the two, could use nuclear developed steam to produce converted water at between $0.50 to $0.75 per 1,000 gallons in multimillion gallon plant installations. As a result of these conclusions, a second stage of this study effort was also initiated in 1958. This consists of a definitive design and cost estimate of a large 350 thermal megawatt light-water reactor which would create sufficient low-temperature steam to produce over 20 million gallons per day of distilled water in a multistage flash distiller of advanced design. In addition, a conceptual design of a smaller pilot plant is also being developed based on the problems involved in the large plant design. The Department of Water Resources of the State of California is contributing up to 40 percent of the cost of the present Fluor study. 4 Fundamental Research in Scale Deposition and Prevention. The formation of scale deposits in distillation equipment, and in some instances, electro- dialysis equipment, is a serious problem, and it is important that methods for eliminating scale be developed. Consequently both fundamental and applied research aimed at attaining a better understanding of scale forma- tion and in developing means of alleviating or controlling it has been initiated. • A fundamental study on factors affecting scale deposition was begun in 1957, and the first phase of that work, consisting of a review and critical evaluation of all available data on scale formation, was completed in 1958. The results indicated a great lack of quantitative data on the mechanism of scale deposition. The second phase of this study, a laboratory investigation of the basic factors affecting scale deposition on heated surfaces, was initiated late in 1958 by the University of Michigan Research Institute. The first part of this work involves studies with simple aqueous systems and will embrace studies on the amount of super-saturation required before scaling occurs and the effect of such factors as velocity, temperature, surface, and presence of crystals on scale deposition. The layout of the test equipment and instrumentation has been designed and some of the equipment has been assembled. In addition, a theoretical study of temperature profiles and temperature gradients in a test section has been completed. Work is prog- ressing satisfactorily and it is anticipated that the results eventually may permit the development of more economical means of scale prevention. Solar Distillation Distillation by means of solar heat has the advantage of eliminating the cost of the fuel energy otherwise required. The diffuse nature of solar energy, however, makes necessary the use of large areas for collec- tion. The major problem in solar distillation is reduction of equipment costs. Research on solar stills having that objective, as well as the objective of increasing efficiency, has been continued. During the year a comprehensive testing and development program on solar stills was initiated. Prototypes of various existing and improved designs are being installed for further development at a central seashore test station near Port Orange, Florida. It is anticipated that the program will result in engineering designs and specifications for practical small units and will point the way for future solar-distillation plants of much larger capacity. 5 RESEARCH AND DEVELOPMENT IN SOLAR DISTILLATION IN 1958 Project Contractor Solar Still Test Program Battelle Memorial Institute Hydrophilic Surfaces on Plastics Films for Solar Stills Franklin Institute Solar Energy Applications New Mexico Highlands University Plastics for Solar Stills Bjorksten Research Laboratories, Inc. Development of Solar Stills New York University (Telkes) Plastic Solar Stills E. I. duPont de Nemours and Co., Inc. (Cooperative agreement) The research and development work in Florida is being carried out through contract with Battelle Memorial Institute, Columbus, Ohio. Both shallow and deep-basin stills have been chosen for evaluation. The first pilot plant to be constructed is of Lof design. It is a deep-basin still with a 2500 square foot area. In evaluating the performance of the deep- basin still, Battelle is making considerable effort to identify the various sources of heat losses. Instrumentation has received much attention. It is expected that the study of heat balances will provide a measure of the effi- ciency of the still and will lead to methods of improving designs and operations. The next two prototypes being built will make extensive use of plastics and are of designs proposed by E. I. duPont de Nemours and Co. DuPont has continued its cooperation with the Office and is supplying the plastics materials for both a 2500 square-foot still using weatherable Mylar as the cover material and a 500 square foot still using Type R film. Both Bjorksten Laboratories and New York University (Dr. Maria Telkes) have contracts to pro- vide designs of prototype stills of several experimentsl types which can be used for the building of additional prototypes at the Florida site. A contract was recently executed with Franklin Institute, Philadelphia, the objective of which is to develop means of producing hydrophilic surfaces .on plastics films for use as a transparent cover for condensing surfaces on solar stills. The production rate of solar stills having such plastics films is much reduced unless the condensing surfaces are completely wettable. An inexpensive surface treatment which would provide a long-lasting wettable surface would greatly enhance the economic feasibility of solar stills. Another recent contract is with new Mexico Highlands University, Las Vegas, New Mexiso. The objective of this contract is to improve methods of -saline water conversion by investigating possible new means of utilizing solar energy. 6 Membrane Processes One,,-.of the primary limiting factors in the use of membrane processes has been',the membranes themselves. Consequently some limited fundamental research investigations, aimed at improving the selectivity, conductance, durability, and other characteristics of ion selective membranes, and the flow rate and durability of osmotic membranes, have been supported by the Office of Saline Water. These investigations, coupled with independent research carried on by industrial firms both here and abroad, have resulted in definite improvements in certain characteristics of ion-selective mem- branes and a decided reduction in cost per unit area of membrane. Membrane research is important, but increased emphasis is also needed on the investigation of the application of the membranes in equipment and the development of cell designs, particularly in the case of electrodialy- sis. Hence the initial phases of a development program in electrodialysis is under way in the Bureau of Reclamation Laboratories, Denver, Colorado. RESEARCH AND DEVELOPMENT IN MEMBRANE PROCESSES IN 1958 Ion-selective Membranes) Brooklyn Polytechnic Institute Membrane Evaluation ) Reverse Osmosis University of Florida Osmionic Southern Research Institute Porous Conductors & Membranes University of Oklahoma Transport Depletion H. G. Deming Biological Membranes Resources Research Inc. Electrodialysis Design Denver Laboratories and Development Bureau of Reclamation Ion-selective Membranes National Bureau of Standards Membrane Research. Research on ion-selective and ion-specific mem- branes was continued during the year with emphasis being placed on the development of a sulfate membrane. Such a membrane would transport the sulfate ion selectively over other ions normally present in saline water, such as chloride and bicarbonate ions. Utilization of such a membrane in conjunction with a conversion process affected by scale deposition might benefit the process sufficiently to reduce materially the total cost of conversion. Heterogeneous membranes of the weak base polyamine type, the benzidine type, and ortho-phenylenediamine type were prepared and are now being characterized and evaluated. 7 The National Bureau of Standards has continued work on the preparation of ion-selective membranes and the investigation of their fundamental elec- trochemical properties. The work has been directed toward the refinement of membrane characterization techniques. A detailed experimental adaptation of some modern theoretical treatments of membrane phenomena from the stand- point of steady-state thermodynamics was -embodied in an apparatus of refined design. Although the apparatus functioned properly during the course of several experiments, it proved to be entirely too delicate for routine laboratory use. A more rugged apparatus has been constructed and is being used for the characterization of several representative membrane materials. This refinement of membrane characterization techniques is directed toward two goals. First, it is hoped that a more fundamental basis for the interpretation of membrane performance in terms of structure can be devel- oped. Second, it is hoped that a general standard set of characterization parameters can be selected so that the performance of a membrane can be predicted for not only the simple electrodialysis process, but also for the reverse-osmosis process and the osmionic process with the additional possi- bility that the parameters will also prove useful in the developments of new processes involving some features of each of the three "pure" processes. In the present investigation the principle need for an improved characterization technique has been in connection with the investigation of laminated, fluid-center membranes consisting of two sheets of a water permeable film, e.g., cellophane, separated by a solution of a high molec- ular weight linear polyelectrolyte. Preliminary experiments have indi- cated that they may be particularly adapted to a combined electrodialysis and reverse-osmosis mode of operation. Current work is directed toward evaluating this possibility. Electrodialysis. Electrodialysis is one of the leading methods for the economical demineralization of brackish waters. The Office of Saline Water has carried out a general program of research and development in electrodialysis at the Denver Laboratories of the Bureau of Reclamation. A four-stack electrodialysis demineralizer unit, made by Ionics, Inc., was first field tested, and then moved to the Denver Laboratories for use in testing membrane life and durability. Although membrane improve- ment was of prime interest at that time, membrane characteristics and the assembly of test equipment were evaluated also. During the current year increased emphasis was placed on the actual cell designs in addition to membrane characteristics. An electro- dialysis development program was initiated at the Bureau of Reclamation Laboratories having as its immediate objective the testing and evaluation of existing electrodialysis units and membranes and the study of possible improvements in the process. Work has been started on improved cell designs. Cooperation with industrial and all other agencies active in electrodialysis will be maintained. 8 In addition to the Ionics demineralizer, two units have been obtained from the Central Technical Institute, T.N.O., in the Netherlands. These consist of a small unit for special laboratory tests and a large unit having 400 cell pairs (800 membranes 16!' x 40") . The large unit was obtained .because of the special features in its hydraulic system and cell design. Membranes for the unit are being obtained from American firms; namely, the American Machine and Foundry Company and the National Aluminate Company. This unit was received late in 1958 and completion of assembly and installation is expected early in 1959. The present success of the electrodialysis process is due primarily to the relatively recent development of ion-selective low-resistance ion- permeable membranes. In order to develop the electrodialysis process prop- erly•it is essential that all available membranes be critically and exhaus- tively evaluated. As an integral part of the Denver program, a contract with the Polytechnic Institute of Brooklyn was executed in October 1958, having as its principal objectives the determination of specific physical and chemical characteristics and evaluation of commercially available and newly developed permselective membranes. This investigation will include determination of such factors as the electrical resistivity, concentration potential, dimensional stability, and transport number. A membrane labo- ratory test manual describing in detail all the tests used in the evaluation of the membranes will be prepared. Osmionisis. The work at Southern Research Institute on the development, construction, and testing of osmionic demineralizers has continued during this period and a small laboratory demineralizer has been constructed and tested. The results obtained indicated that the design equations predicted performance adequately. A clamp-membrane stack containing 20 double-effect cells recently has been assembled and is being tested. The membranes in the clamp-membrane stack are 4 inches x 30 inches and the average distance between membranes is 0.028 inch. The primary purpose of the 20-cell stack is to check the design and components of the stack prior to fabrication of an 80-cell unit. The small unit will have a capacity of about 0.8 gal/hr. Under similar conditions, the 80-cell unit will have a capacity of approximately 5 gal/hr. Preliminary cost estimates were prepared for the osmionic process based on commercial plants of different capacities demineralizing water containing 2,000 to 3,500 ppm dissolved solids. Membrane cost of 60 cents and $1.00 per square foot for both double-effect and triple-effect cells were assumed. The cost studies indicated that the osmionic process may be economically feasible under favorable geographic and membrane-cost conditions. Current investigations will provide a sounder basis for later cost studies. Porous Conductors and Membranes. The investigation of adsorptivity of porous conductors and their use in saline water demineralization was continued during 1958. The soundness of the principle was demonstrated in the first year's work and a primitive demineralization cell was constructed and operated. That cell contained graphite electrodes separated by anion- 9 selective membranes. On concentrations up to 0.01 normal saline solutions, the cell gave fairly complete demineralization. The membrane was made necessary because no suitable anion-responsive electrodes could be found. Consequently during this period emphasis was placed on the development of anion-responsive electrodes and to the improvement of the demineralization capacity of the present cation-responsive electrodes. The results have established the fact that electrically controlled adsorption-desorption gives a technically feasible demineralization process. Current work includes studies on such materials as graphite-ion exchange resin mixtures. Dacron felt, sulfonation of graphite, and carbon electrode materials other than graphite. Transport Depletion. In the purification of saline water by ion- selective membranes, the membranes interposed across the path of the current through every membrane stack or cell are alternately cation-selective and anion-selective. "Transport depletion" is a variant of this general practice. Its distinctive feature is that the membranes or controls are all of the same character. With this arrangement there is depletion of the solution at one surface of each membrane and enrichment at the other surface. Between each pair of successive membranes or controls in the cell is a depleted zone and an enriched zone. The problem is to keep them apart and to withdraw them separately. This investigation, which was concluded in 1958, included studies on cell designs, membrane properties, effect of diffusion, flow rates, and various controls, e.g., hydrous metallic oxides, gels, liquids, etc. The investigation was under the direction of Dr. H. G. Deming of Sarasota, Florida. The results indicated that transport depletion is technically feasible and it is believed worthy of additional study. Reverse Osmosis. The continuation of the work on reverse osmosis at the University of Florida has been directed primarily at developing improved ion-restraining or osmotic membranes. Previous work has shown that cellulose acetate membranes were capable of rejecting a very high percent of the ions of a salt solution when subjected to high pressure. The limited durability of the membranes, associated with hydrolysis of the ester groups, prevented their use in demineralizing saline waters. However, an investigation of those and other membranes indicated the structural requirements of a suita- ble membrane for this purpose. In order to obtain a high salt rejection and flow rate, as well as extended durability, the membranes must be inert to chemical attack by constituents of the saline solution and possess a high concentration of hydrogen bonding sites with crosslinking at some optimum intervals along the polymer chains. The principle criteria for judging films are (1) salt rejection, (2) flow rate, and (3) durability. 10 Cellulose acetate films have met the first criteria and might pass the second, but they fail in the third. No polymer other than cellulose acetate has been found to possess the desired salt-rejecting ability. During the period of this investigation, however, the synthesis of polymers according to the requirements learned from the experiments on cellulose acetate has resulted in the preparation of a few durable films of high salt-rejecting ability. The flow rate, however, was low and variations of the film to increase it led to low salt rejection. Thus cellulose acetate may meet criteria (1) and (2) ; while the new polymer can meet either (1) and (3) or (2) and (3), but no film has met all three to date. Biological Membranes (Algae) . The initial phase of the evaluation of the use of algae in sea-water conversion consisted of a literature survey. The survey did not uncover pertinent information on the salt uptake of marine algae and it was necessary, therefore, to undertake fundamental research in a virgin area, namely, the selection of various types of algae whose characteristics are favorable for the use intended. Over 100 differ- ent species of marine algae have been cultured to date and several of those developed from moderately dense to dense cultures within 24 hours. Analyses of .the various solutions for sodium and chloride uptake are now under way. Of .the number analyzed to date, about four to six different species have been found to accumulate sodium ions. The present work is continuing and has as its primary objectives (1) the search for additional species of algae with higher salt-concentrating powers, (2) the search for means to increase the effect, and (3) the study of means by which selected species of algae can be made to secrete the absorbed salt. Freezing; Processes Theoretically, if ice frozen from salt solution is washed free of salt and then melted, fresh water will be obtained. Unfortunately, freeing the ice of salt has been difficult to do because the ice occludes or entraps brine between the interstices of the crystallite forms. This problem, how- ever, has been overcome within the past two years. Along with the develop- ment of more efficient counter-current washing methods, freezing the brine directly by evaporation has been demonstrated to be technically feasible. The inherent advantages of a freezing process indicate that such a method when completely developed should be able to compete economically with the developments in the distillation field. RESEARCH AND DEVELOPMENT IN FREEZING IN 1958 Project Contractor Direct Freezing Process Carrier Corporation Direct Freezing-Secondary Refrigerant Cornell University (Wiegandt) Zone-Purification Battelle Memorial Institute 11 Direct Freezing-Process. One of the more promising freezing methods investigated under contract is that developed by Carrier Corporation which utilizes the direct-freeze, counter-current-washing separation process. Refregeration is accomplished by mechanical compression or absorption of water vapor, or a combination of both. Continuous production at rates of 50 to 100 pounds of ice per hour has been realized. Although the economics of the direct-freeze separation process appear promising, current cost estimates must be verified by larger-scale operations. Present results indicate that by good design, efficient operation, and low maintenance, the costs for freezing processes may ultimately be reduced to the order $0.50 to $1.00 per 1000 gallons. In order to obtain a more valid economic and technical appraisal of the process, the Carrier Corporation is designing a 15,000 gpd pilot plant, which they propose to assemble and erect for complete evaluation. This phase of the program will permit the necessary experimental work for deter- mining optimum conditions of operation, maximum production capacities, and additional economies which can be realized in large-scale production units. Zone Freezing. Initial phases of the research by Battelle Memorial Institute on the possibilities of adapting the zone purification process for salt-water conversion were completed. After a technically feasible process was investigated, a preliminary estimate indicated costs in a range of $3.00 to $7.00 per thousand gallons. As a result, the National Science Foundation was requested to consider the support of the additional basic research proposed by Battelle. Battelle also planned to carry out a detailed engineering evaluation on the basis of experimental data now avail- able. In addition, it intends, by means of small-scale experiments, to explore possible improvements and process designs that might be indicated by the further analysis and evaluation. The objective would be to uncover possible methods for bringing the zone-purification process into a more promising cost range. Fund limitations have made it advisable to postpone this additional work until the next fiscal year. Direct Freezing - Secondary Refrigerant. Another approach to the problem of saline-water conversion by the. freezing process is now in progress at Cornell University under the direction of Professor H. F. Wiegandt. This is the investigation of the refrigeration cycle in which an immiscible refrigerant, such as butane or isobutane is vaporized in direct contact with salt water. The butane vapor and ice crystals rise to the top of the salt solution: The butane gas is withdrawn and compressed and the heat of compression is utilized to melt the ice after the ice has been washed free of salt. Although considerable progress has been made, further development of the freezing process is anticipated. Recently, proposals have been received suggesting methods for improving the efficiency of the direct freeze cycle and for scaling-up equipment for commercial operations. The increased interest in freezing is expected to stimulate additional investigations leading to the development of a low-cost desalination process. 12 Other Research and Developrnent The investigation of the desalinization of saline waters by use of organic solvents was continued by the Texas A&M Research Foundation under a new contract. Emphasis was placed on the search for more efficient com- pounds and operation of a laboratory model, particularly on brackish waters. The next step in the process development will probably be the design, con- struction, and testing of a small pilot plant for brackish water treatment in order to obtain further information on possible economic feasibility of the process. A small exploratory research investigation having as its objective a feasibility study of the possibility of utilizing ultra-high frequency electrical fields as a means of demineralizing saline water was completed during this period at the Alpine Laboratories, Ltd., Colorado Springs, Colorado. Many tests were run on samples of synthetic saline water (3.5% sodium chloride) and on samples from Great Salt Lake. Under the conditions of the experiments, however, no reduction in salt content was noted. An investigation calling for an exploration and evaluation of the following ideas as a possible means of desalinization was initiated at the Applied Science Laboratories, Inc., under the direction of Dr. Arthur Rose; (a) hydrocarbon hydrate formation; (b) use of chelation in demineralization; (c) use of ion retardation resins; and (d) utilization of the energy in the concentrated waste brine produced in any demineralization process. 13 COORDINATION ACTIVITIES The Saline Water Conversion Program is presently a cooperative endeavor with private and governmental groups. The Saline Water Act provides that the functions of the program are to include cooperation with other agencies and the correlation and coordination of activities in this field. Therefore, in addition to the program of contract research, the stimulation of effort by others to obtain the objectives of low-cost conversion has been a. basic purpose. In accordance with these objectives the Office of Saline Water has performed various functions generally termed the coordination activities of the program, included among which are the following: Cooperation, with State and Federal as well as foreign agencies interested in conver- sion; reviewing work of others in this field and correlation of this work with that of the Office of Saline Water; supplying many requests for information on the subject; the soliciting new ideas for conversion from all interested parties and the stimulation of interest in presenting new methods of conversion to the program; publishing progress reports that cover the results of contract research; preparing technical papers for scientific meetings; and conducting special surveys and studies closely related to the development of processes. Each year the Office of Saline Water has prepared a summary tabulation listing all known activity both in this country and other parts of the world in saline water conversion research and development. A list of these activities is included in. the Appendix. Process Research and Development under Other than Office of Saline Water Sponsorship A brief summary of all known research and development activity on saline water conversion processes throughout the world is presented in .the Appendix. Although the process investigations conducted by the Office of Saline Water have already been discussed, they are listed in the table to \complete the summary. Although the following paragraphs review work sponsored by others, the research at the University of California. has for convenience been included under Cooperation with States and the reader is referred to that section for information on the work at the University. Distillation. Several commercial organizations both in this country and abroad have continued their development of improved distillation processes and equipments of all sizes. In addition, large multi-million - gallon per day plants are being constructed or bid on in places like Nassau, Curacao, and Kuwait. Each of those plants will have individual characteristics as the competing companies strive to develop lower cost and more efficient equipments. 14 The United States and British Navies also continue in their testing and development of improved distillation techniques. Work of that nature is being conducted by the Naval Engineering and Experiment Sta.tion, Annapolis, Md. , Naval Civil Engineering Laboratory, Port Hueneme, Cali- fornia., and British Admiralty Materials Laboratories, Poole, Dorchester, England, and a. light weight military distillation unit is being developed by the U. S. Army, ERDL, Fort Belvoir, Virginia. These activities are summarized in the Coordina.tion Table at the end of this report. Solar Distillation. The use of solar stills for desalinization pur- poses continues to a.ttra.ct interest in many parts of the world. In Algeria., Mr. C. Gomella of the Society for the Study and Treatment of Water is actively engaged in research and development. Plans are being made for experimental operation of solar stills that will provide the best and cheapest method for employing local labor and materials. Interest in desal- inization of saline waters by solar distilla.tion continues also in Morocco, under the direction of Mr. Robert P. Ambrooge, and in other parts of North Africa. In Australia., the Commonwealth Scientific and Industrial Research Organization ha.s sponsored development of solar stills to meet local requirements, and a number of small solar stills are in use. Also, a solar still wa.s designed for use in certain a.rea.s of the Antarctic. In Spain, the National Commission of Special Energies ha.s begun studies on solar distillation. Dupont has supplied tha.t organization with plastics materials for experimental work. Dupont is also supplying exper- imental pla.stics to the National Physical Laboratory of Israel. This lab- oratory has been developing solar collectors of several types. Professor Georgio Nebbia. of the University of Bologna in Italy is continuing his experiments with solar stills. In Russia. solar distillation has been under study in various labora- tories associated with the Academy of Sciences of the U.S.S.R. Considera- tion has been given to several types of stills; for example: the simple box type, inclined roof type, those using mirrors for concentrating sun rays, and combinations of solar water hea.ters with solar stills. In the United States, a. number of groups axe continuing their activities in the field of solar energy utilization. The Associa.tion for Applied Solar Energy with hea.dquaxters in Phoenix, Arizona, continues to assemble pertinent information and publications. The Massachusetts Insti- tute of Technology a.nd the Universities of Wisconsin and Florida. are studying the broad field of solar energy utiliza.tion, although this is not a major project with these institutions. The University of California is studying solar stills as one of its research and development activities in its sea-water conversion program. Membrane Processes. In the United Sta.tes a number of commercial and research organizations are conducting resea.rch and development in electro- dialysis. Among the commercial firms are Ionics, Inc., National Alumina.te 15 Company (Nalco), American Machine and Foundry Company (AMF), and the Permutit Company. The Ionics, Inc, has conducted further work on membranes and unit designs and reports additional plant installations both in this country and abroad, including one at Coalinga, California., where a local shortage of fresh water is being met by electrodialysis treatment of brackish sources as an alternate to more costly transportation of water from distant sources. In the membrane field, the National Aluminate Company has conducted considerable membrane development and in 1957 announced that it was offer- ing membranes at approximately $1.00 per square foot in lots of 5,000 square feet or more. The American Machine and Foundry Company has fur- thered its membrane developments during the current year and is utilizing a. radiation grafting technique to produce the desired ion exchange proper- ties. The Texas Electric Service Company is continuing a. development program in electrodialysis in cooperation with Texas Christian University seeking to improve the design and economics of the process. The New Mexico Institute of Mining and Technology reports development and testing of a laboratory electrodialysis unit utilizing relatively low voltages and current densities. The purpose of the work is to develop small units for possible use in homes or on ranches in arid areas. The large electrodialysis unit in South Africa. (2,400,000 gpd) devel- oped by the SACSIR and the Gold Mining interests for use in demineralizing brackish gold mining waters has been under construction during the year and it is understood that the plant will soon be completed. In Japan the interests in electrodialysis concerns largely its use in salt manufacture rather than fresh water production. The work has resulted, however, in the development of both membranes and cells for this purpose, some of which may be applicable to saline water conversion research. It is indicated that. the work is in the advance development stages rather than in the marketing phase. The Asahi Chemical Industry Company, Ltd. and the Asa.hi Glass Company, Ltd. are active in this work. Freezing Processes. In Japan there has been interest in., the demineralization of sea water, not so much to obtain fresh water as to extract salt. Research has been conducted on va.cuum freezing processes using continuous centrifugal separator for ice removal. In France, Trepand, Inc., has been making ice from sea water for use in fish preservation. This company was reported to have plans for a sea- water conversion plant using an adaptation of the ice production process; however, no further information has become available. In Israel, the freeze-evaporation process (Za.rchin system) is reported to-be under investigation. In Jugosla.via., the Meta.11urski Insti- tut has conducted experimental work based on the freezing principle. Although efforts have been made to learn more about these developments, it has not been possible to obtain detailed information. 16 General Surveys and Studies A number of surveys and studies closely related to the research and development on conversion processes has been conducted during the Program and are reviewed in some detail in the previous Annual Report: These activities have included: (1) an inventory of published and unpublished information on the characteristics of the saline waters of South Dakota, (2) survey of the potential needs for converted water for irrigation in Texas and California, (3) an analysis of the minimum thermodynamic energy requirements for conversion processes, (4) a study of the disposal of waste brine residues, and (5) a study of the availability of geothermal energy for conversion processes. U. S. Geological Survey - Saline Water Studies. The Geological Survey under its own program is conducting studies of the nation's saline water resources. The Survey has prepared a generalized overall report for the United States and has begun a. study of saline water sources in several states. Publications to date include Water-Supply Paper No. 1374, "Pre- liminaxy Survey of the Saline Water Resources of the United States," by R. A. Krieger, J. L. Hatchett, and J. L. Poole; Water Supply Paper No. 1365, "Saline Water Resources of Texas," by A. C. Winslow and L. R. Kister, and Water Supply Paper No. 1428, "Saline Water Resources of North Dakota," by C. J. Robinove, R. H. Langford, and J. W. Brookhart. These reports are based on available information and not on field studies ini- tiated specifically to obtain the' data. The Geological Survey is contin- uing studies of a similar nature on New Mexico and Oklahoma.. Saline Water Laboratory. Although much progress has been made in the development of conversion processes since the Office of Saline Water was established, additional effort and facilities are required to carry the processes now under development to a practical stage. Present facilities are not adequate for field testing either small pilot plants, or ideas for new processes; in addition, process components must be improved by labora- tory research if complete system costs are to be reduced. The Technical Research Group, Inc. , New York City, as consultants to the Office of Saline Water, were asked to study and report on the "Problems Related to Establishment of a. Laboratory for Research in Deminera.lization of Saline Water." They report that an adequate facility could be provided for approximately $2,000,000, and should be staffed and operated at an annual rate of approximately $1,275,000, This matter is being given further serious consideration. Cooperation with States Under the Act of 1952, the Department of the Interior has welcomed state and local cooperation covering either joint financial contributions or that involving only the exchange of information and other cooperation. Cooperation with many of the states has been carried out on an informal basis. However, two States have entered into formal agreements with the Department and several others have similar agreements under consideration. 17 The recently authorized demonstration plant program has made even greater cooperation with the states desirable. California is the only state known to be sponsoring a program of research and development on conversion methods. California.. COOPERATIVE AGREEMENT. In April 1958, a cooperative agreement for the exchange of information and cooperation in saline water conversion was entered into between the State of California, Department of Water Resources, and the Department of the Interior, Office of Saline Water. The California agreement has since been extended to include joint financial support (State 40 percent, Federal Government 60 percent) for a research and development contract on the feasibility of utilizing nuclear energy in saline water conversion. The State is also assisting in obtaining data on sites which are proposed for plants under the demonstration program. UNIVERSITY OF CALIFORNIA AND STATE DEPARTMENT OF WATER RESOURCES. Since 1952 the University of California. has sponsored a program of research in sea. water conversion, having objectives similar to those of the Office of Saline Water. The work has been conducted at both the Berkeley and Los Angeles campuses. The activities have been under the direction of Everett D. Howe, Professor of Mechanical Engineering at Berkeley. Cooperation has been maintained with the Office of Saline Water from the beginning of the work and the activities at the University were summarized in the Saline Water Conversion Report for 1957. Beginning with Fiscal Year 1958, increased emphasis has been placed on the conversion activities. Additional funds have been appropriated by the State for use by the California Department of Water Resources; the University has expanded its research and development work. The Department of Water Resources, in cooperation with the University, is studying the possible uses of nuclear energy as a. source of heat or electrical energy. This work, which has been under the direction of Harvey 0. Banks, Director of the Department, is primarily directed toward the collection and evaluation of design, operation, and maintenance data. from existing and planned conver- sion units in the United States and abroad. Activities at the University's Berkeley-Richmond campus and the Los Angeles campus have included work on solar distillation, vacuum flash (low temperature difference) distillation, ion exchange, ion filtration (reverse osmosis), solar heat storage, nuclear reactor studies, short path distilla- tion, surface skimming, therodynamics and economic analysis, and properties of sea water. . In addition other studies are in progress which have not yet reached the report stage. These include vapor compression distillation, magnetic equipment for scale prevention, centrifugal multiple-effect stills, and additional solar still designs. The Department of Water Resources ha-s initiated prepilot plant water deminera.liza.tion studies for several locations in California. Processes con- sidered have included membrane methods for brackish water conversion, vacuum flash distillation by low temperature difference for,sea water conversion, 18 utilizing both industrial waste-heat sources and the thermal potential of sea water in coastal submarine basins and canyons. It has been found that the submarine canyons off the coast of California have temperature differentials of from 150 to 250F at depths of from 2000 to 3000 feet. In addition to the prepilot plant planning, surveys are to be made by the Department of Water Resources of possible energy sources such as wind power, ocean waves and tides, geothermal sources, solar radiation, and industrial waste heat. Also surveys of brackish water availability are being compiled from local and state sources. Economic studies made by the Department indicate that the probable total cost of conversion must approach $80.00 per acre foot to be useful to consumers of domestic, municipal, and industrial water in California. New Mexico. The State of New Mexico ha-s entered into a cooperative agreement with the Department of the Interior for the exchange of informa- tion and cooperation in saline water conversion. The Office of the State Engineer will cooperate with the Office of Saline Water in obtaining data. on sites which have been proposed by a number of New Mexico communities for the plants authorized under Public Law 85-883. Cooperation with Federal Agencies In addition to the active research work sponsored by the Office of Saline Water in Government laboratories at the Bureau of Standards and the Denver Laboratories of the Bureau of Reclamation. Cooperation with some joint participation in technical studies has been maintained throughout the program with other Departments of the Government as provided by the Saline Water Act. Department of Defense. During this past year, the close coordination of the Office of Saline Water and the various cognizant activities of the Department of Defense continued. Two formal meetings were held and repre- sentatives of the Department of Defense, Army, Air Force and Navy were present. A thorough review was made of the activities of ea.ch organization in the field of saline water conversion and proposals for joint research and development projects were discussed including an investigation into the' possible utilization of thermo-electric phenomena. for saline water distilla- tion and basic research in scale prevention. The latter study was under- taken independently by the Office of Saline Water as the Department of Defense did not desire to participate. In addition staff members of each of the above organizations have independently discussed matters of mutual interest and have visited each others ' developments. This exchange of information is beneficial to all and will be continued during the next year. Atomic Energy Commission. Cooperation with the Atomic Energy Commis- sion was initiated under Public Law 82-448 and reemphasized under Public Law 84-111. The results of one cooperative investigation, "Study of the Applicability of Combining Nuclear Energy with Saline Water Distillation Processes," were published as Office of Saline Water Progress Report No. 19. 19 A second investigation, "A Preliminary Design Study of an Optimum Nuclear Reactor-Saline Water Evaporation Process," is now in progress. In addition, during the past year, increasingly frequent technical discussions have been held between staff members of both organizations. As a result, the desirability of a cooperative arrangement for the devel- opment of a process steam reactor by the Atomic Energy Commission for use with future conversion plants in high-cost fuel areas, is being considered. International Cooperation Administration. During the year specific information was provided in response to a number of requests from ICA and ICA Missions for information on various aspects of saline water conversion, particularly distillation of sea water including solar distillation. Interested areas included the Caribbean, South America, and North. Africa. In addition, the Office of Saline Water provided information and advice regarding the possibilities of eventually installing saline water conversion production plants in several water-short foreign areas. OSW staff members participated in several conferences with ICA representatives in considering that program. Department of Health, Education, and Welfare., Close cooperation with the Department of Health, Education, and Welfare, particularly the Water Supply and Pollution Control Program, has been maintained. In the past ,joint sponsorship on one research investigation was undertaken and it is anticipated that other such beneficial arrangements will materialize in the near future. In response to specific requests from the Public Health Service, a representative of the Office of Saline Water has reviewed the Saline Water Conversion Program before certain groups or organizations, such as the National Technical Task Committee on Industrial Wastes. Personal contacts are maintained with personnel in the Health, Education, and Welfare Washington Office and with those in the Robert A. Taft Sanitary Engineering Center, Cincinnati, Ohio. National Science Foundation. In accordance with the cooperative agreement between the National Science Foundation and the Department of the Interior, a proposal for basic research which evolved as a result of contract research on zone freezing was submitted to the NSF for considera- tion of support. Toward the end of the year the Office had under exploration the possible use of foreign currencies for scientific purposes under the author- ity contained in Section 104 (k) of the Mutual Security Act. This activity was a part of the Department's cooperation with the NSF in establishing a program for use of such funds. Various detailed information was provided in response to NSF requests in the compiling of their surveys and reports on over-all Government research activities. 20 Foreign Activities Unesco. The Advisory Committee on Arid Zone Research together with the Iranian..Government sponsored the Symposium on Salinity Problems in Arid Lands in October 1958, in Teheran, as scheduled. Included were two_., sessions on desalting of water at which eleven papers describing saline water conversion research and development were presented by representa- tives from Algeria, Italy, Morocco, The Netherlands, Union of South Africa, United Kingdom, USSR, and the United States. The Directory of Laboratories engaged in saline water conversion was compiled by the UNESCO Secretariat. It is planned that- this Directory together with the Proceedings of the Symposium will be published by UNESCO. Future activities under the Subcommittee on Salinity Problems on which Mr. David S. Jenkins serves as United States member are to include periodic updating of the Directory, some studies on maximum salinity tol- erances for drinking water under conditions encountered in arid lands, and such symposia. as may be needed within the next few years. Organization of European Economics Cooperation (OEEC). Most of the formal international cooperative research established under Working Party No. S of the OEEC has been essentially completed, as follows: The Netherlands T.N.O. electrodialysis equipment has been developed and is being marketed in units having capacities up to approximately 50,000 gallons per day on water of 4,000 ppm salinity. The U.K. scale prevention research on`improvement of vapor compression distillation has been essen- tially completed with development of data on forced circulation and dropwise condensation promoters. The solar distillation cooperation which was centered in Algeria, consisting of exchange of technical information, is being continued on an informal basis. Other Foreign Activities. Word has been received that research and development of saline water conversion processes is being continued or planned in a number of countries as shown in the Table of Saline Water Research and Development Activities, (see appendix) . Among these many developments are those on electrodialysis in the Netherlands, Union of South Africa, Russia, England, Japan, and Israel; distillation in Great Britain, France, Israel, the Netherlands West Indies, and Russia; freezing in France, Yugoslavia, Israel, Russia, Italy, and Japan; solar distillation in Spain, Morocco, Australia, Algeria, Russia, Italy, and Cuba; and others. Information has been received from McGill University, Montreal, Canada, that the activity under the Brace bequest consists of planning for the sub- sequent physical research program. 21 Stimulation of Interest in Research and Development Among the activities which serve directly to stimulate interest in research and development on conversion and served also to further encourage . cooperation of the various researchers both in this country and abroad was the Symposium on Saline Water Conversion. The Symposium which was sponsored jointly by the Office of Saline Water and the National Academy of Sciences was held in Washington in November 1957. The Proceedings of the Symposium containing some 45 papers was published in 1958. Inquirers concerning the availability of this document should be addressed to the Publications Office, National Academy of Sciences, 2101 Constitution Avenue, N. W., Washington, D. C. During 1958, two consultants for the Office of Saline Water, Dr. Luois Koenig and Dr. H. Horton Sheldon, visited the following univer- sities in order to acquaint certain staff members of those organizations with the objectives and accomplishments of the program and to solicit new ideas in the form of proposals: University of Kentucky (Lexington) University of Cincinnati Ohio State University (Columbus) St. Marys University, San Antonio, Texas University of Texas, Austin, Texas Rice Institute, Houston, Texas University of Houston, Houston, Texas Texas Technological College, Lubbock, Texas Baylor University, Waco, Texas Technical papers were presented at scientific meetings during 1958 as follows: Mr. David S. Jenkins, Director, Office of Saline Water discussed "Fresh Water for Arid Lands" at the Symposium on Salinity Problems in Arid Lands, Tehran, Iran, October 11-18, 1958. Dr. W. S. Gillam and Mr. J. J. Strobel, of the Office of Saline Water staff, prepared a paper, "Summary of Technical Developments in Saline Water Conversion" for presentation at the American Chemical Society's meeting at San Francisco, April 15, 1958. The paper was presented by Mr. Edward A. Cadwallader. The Princeton University Conference on Water Supply held on January 29 and 30, was attended by Dr. W. S. Gillam, who presented a paper on treatment of saline water. A total of 21 research and development progress reports are now available from the Office of Saline Water. Five of the reports were published during 1958. 22 Demonstration.Plant Program On September 2, PL 85-883 was enacted authorizing the construction of demonstration plants for the production, from saline or brackish waters, of water suitable for agricultural, industrial, municipal, and other bene- ficial consumptive uses. A copy of that law is reproduced in the appendix of this report. This law specifically provides that the demonstration activity should not be in derogation of the research and development pro- gram, thus recognizing the need for continued research and development of lower-cost processes. Briefly the law provides that at least five such plants shall be constructed and test operated in a 7-year period from enactment. Three of the plants are to be designed for the treatment of sea water and two for brackish water. The first process for experimental demonstration is to be selected by the Secretary of the Interior within six months after enactment of the law and the selection of four other processes shall follow at three month intervals thereafter. Inquiries have been received from a number of communities expressing their interest in having one of the authorized plants located in their areas. As a result of this interest the Office of Saline Water has pre- pared a preliminary site guide to be used in the collection of information that will be needed for the consideration of the relative merits of various locations. The information needed will generally involve the: a. Type of process b. Locations where water is needed c. Availability of saline water supplies d. Local factors affecting the proposed plant e. Cooperation of local State and/or local agencies; and f. Demonstration value of plant. Cooperative arrangements have been and are being negotiated with interested States. Whenever possible the proper cognizant State organi- zation will be asked to assist in the selection of proposed sites and in supporting the program. A demonstration plant is defined, for the Public Law, as follows; As used in this joint resolution, the term "demonstration plant" means a plant of sufficient size and capacity to establish on a day-to-day operating basis the optimum attainable reliability, engineering, operating, and eco- nomic potential of the particular sea water conversion process on the brackish water treatment process selected by the Secretary of the Interior for utilization in such plant. 23 ADMINISTRATION Advisors Following enactment of the Saline Water Act in 1952, a group of eight scientific and industrial leaders agreed to serve as Advisors to the Secretary on saline water conversion. The Advisory Group is comprised of the following: Mr. J. J. Cronin, Vice President, General Motors Corporation Dr. Lee A. DuBridge, President, California Institute of Technology Dr. Frederick L. Hovde, President, Purdue University Dr. George D. Humphrey, President, University of Wyoming Dr. Louis Koenig, Louis Koenig Research Mr. Robert Lusk, Editor-Publisher, "Huronite and Daily Plainsman" Mr. Sheppard T. Powell, Consulting Engineer Dr. Robert G. Sproul, President, University of California The Advisors met on March 25, in Washington, and as a result of the meeting made a number of recommendations to the Secretary for an expanded program including the recommendation that additional funds be supplied for carrying out the activities. In addition to advising the Secretary on the broad policy aspects of the program, several members of the group have provided direct assistance to the Office of Saline Water in technical and other matters relating to the research and development work. Congressional Hearings During 1958 the Director and certain staff members of the Office of Saline Water testified before and provided information to (a) the House Committee on Appropriations; (b) the Senate Committee on Appropriations for regular budgeted amounts, and also for supplemental appropriations; (c) the Senate Subcommittee on Irrigation and Reclamation; (d) the House Subcommittee on Irrigation and Reclamation; and (e) the House of Representatives Subcommittee on Government Operations. Hearings before the Subcommittee on Irrigation and Reclamation of the Committee on Interior and Insular Affairs, United States Senate, on S.J. R 135 and S 3370, bills pertaining to saline water conversion plants, were held March 20 and 21, 1958. Much data and information was presented and the Committee on Interior and Insular Affairs in their Senate Report No. 1593 summarized their findings and recommended that the resolution pass. 25 The Subcommittee on Irrigation and Reclamation, House Interior and Insular Affairs Committee held hearings on S. J. Res 135 on July 14, 1958. A brief summary of those hearings is contained in House Report No. 2450. The Committee recommended enactment of Senate Joint Resolution 135, as amended. On September 2,. 1958, Congress enacted Public Law 85-883 (S. J. Res. 135), which provides for the construction of saline water conversion demon- stration plants. ° On April 15, 16, 17, and 18, 1958, a Subcommittee on Governments Operations, House of Representatives, held hearings on the Saline Water Program. This was an exhaustive and detailed review of the entire program and testimony was presented by the Assistant Secretary of Interior, the Director and staff members of the Office of Saline Water, and other scien- tists and engineers from government, universities, industry, research organizations, and individuals. The results of that review are summarized in House Report No. 2551 wherein a number of constructive suggestions for augmenting and improving the program were made. Fiscal Year 1960 With the enactment of Public Law 85-883 (S.J. Res. 135) providing for the construction and operation ofsaline water conversion demonstration plants, there are now two concurrent phases of the Saline Water Conversion Program. One continues the research and development of: improved, low-cost processes already in progress pursuant to the Saline Water Act of July 3, 1952, as amended. The other is the construction, operation, and maintenance of not less than five saline water conversion demonstration plants pursuant to Public Law 85-883, enacted September 2,, 1958. Research and Development Program. The new work to be undertaken during fiscal year 1960 depends upon results obtained in the current research and development projects and also upon the appropriations made for the Saline Water Conversion Program. The research and development activity can be divided into seven major categories: 1. DEVELOPMENT OF ROTARY STILLS. Research on small rotary stills will continue in order to develop equipment for household and similar use. Additional field testing and further development are necessary in the large Hickman rotary vapor compression still together with analyses of all data in order to determine feasibility of the future application of such type stills for large-capacity production plants. 2. OTHER DISTILLATION. Further research and development on , several flash distillation processes and systems are needed in order to determine which ones are most promising. Additional research on forced- circulation and dropwise condensation is needed as a means for improving the vapor compression distillation cycle. There is also need for continued testing and 'development of improved techniques and materials- on the Badger 26 long-tube vertical distillation pilot plant, both to improve the present cycle and to assure continued -improvements in this system even after it is advanced into the large pilot sizes of a million gallons or `more. There is also a need for additional basic research on factors of importance to all distillation processes including research on scale, corrosion, heat transfer,. and use of low-cost materials such as concrete. 3. SOLAR DISTILLATION. Logical development requires continuation and expansion of the testing and development program on solar stills initi- ated last year at a test site near Port Orange, Florida, including design and construction of new prototype stills for tests. In order to reduce cost, research is essential on materials applications. 4. MEMBRANE PROCESSES. Because of the importance of electro- dialysis in the conversion of brackish waters, expansion of electrodialysis development program of the Bureau of Reclamation laboratories is of major importance. The new program includes design and development of an improved electrodialysis process and testing and evaluation of various membranes and operation of experimental electrodialysis equipment of the two major types commercially available. Additional development on the osmionic proc- ess, including operation of a prototype unit, is now required for evaluation of possibilities for pilot plant application. Additional basic and applied research in improved membranes and on other membrane processes must be car- ried out as a possible means of lowering costs. A final evaluation of the osmotic process is necessary to determine its area of most practical use. 5. FREEZING PROCESSES. The possibilities for, lower conversion costs, which have become apparent through research on methods utilizing freezing, require a greater emphasis on the development of freezing proc- esses. Pilot-plant operation of a freeze-evaporation system and accleration of laboratory developments on direct freezing methods are in order. Con- tinuation or initiation of research on other freezing systems or components of systems with possible application to the more advanced conversion systems utilizing freezing techniques is also needed for further improve- ments. 6. OTHER PROCESSES, INCLUDING NUCLEAR ENERGY COMBINATION. Research is needed on elements of proposed combination multiple purpose plants utilizing nuclear energy, as an adjunct to design and engineering. Operation of a small pilot plant for brackish water conversion based on the solvent extraction process is planned in continuation of its evaluation for practical use. Continuation of applied research on other solvent extraction possi- bilities may lead to further improvement. 7. EXPLORATORY RESEARCH, SURVEYS, AND EVALUATIONS. Support of basic and exploratory research on new ideas presented is essential in order to point the way to possible new conversion processes with greater economic promise than those that are being developed so far. 27 As a result of limited basic and exploratory research- of this kind, two new conversion methods have been developed from a scientific principle or idea up to the pilot plant stage. Additional. fundamental information is needed on potential processes, properties of saline solutions, corrosion, membranes, hydration and other physical and chemical phenomena. A number of technically feasible new approaches have been proposed and the best of these should be explored and developed as soon as funds are available. In addition, further improvement of the test site and facilities near Port Orange, Florida, is to be made to the extent shown to be necessary based upon operations that are now in process or planned. Evaluations of various kinds by consultants and other Governmental agencies are included in this category. Demonstration Plant Program. It is planned in FY 1960 to completely activate the program to carry out the various phases of the work. This will include the- study and selection of the conversion processes and sites for plant construction, and contracting for the engineering of the first conversion plants. It is also planned to have a contract ready for execu- tion which will provide for starting building of the first plant as soon as possible in Fy 1961. 28 APPENDIX 29 AUTHORIZATION A copy of the 1952 Saline Water Act and the 1955 amendment thereto, as well as Public Law 85-833 discussed'in this report (see Demonstration Plant Program and Congressional Hearings) are printed below.

Providing for the construction of demonstration plants'for the production, from saline or brackish waters, of water suitable for agricultural, industrial, municipal, and other beneficial consumptive uses. Whereas official Government reports show .unmistakably that the United.States population is multiplying at a rate which by 1980 will triple the demand for supplies of fresh water, which if not available will adversely affect the national defense by jeopardizing the economic welfare and general well-being of vast segments of the population of the United States, as well as the population of some of our Territorial.possessions; and Whereas inany cities, towns, and rural areas are already confronted by shortages of potable water that imperil health; and Whereas the expanding population, industry, and agriculture of the United States are becoming increasingly dependent upon an assured augmented supply of fresh water while the future welfare and na- tional defense of the United States rest upon increased sources of fresh water; and Whereas research by governmental agencies, educational institutions, and private industry has brought. about the evolution, on a limited scale,of methods of desalting sea water and the treatment of brack- ish w,,Ater which give promise of ultimate economical results; and 117'liereas the United States Government has the responsibility, along with safeguarding the national defense, and protecting the health, welfare, and economic stability of the country, to transform these experiments into production tests on a scale not possible of achieve- ment otherwise; and Whereas the Congress recognized its responsibility in this field by the enactment in 1952 of the Saline Water Act (66 Stat. 328), re- 42 USC 1951 affirmed its position by the amendments to such Act in 1955 (69 Stat. et 198) ; and the legislative history of such Acts reveals that the Con- tress.recognized even then that the time had arrived for tackling the problem more realistically and effectively,but unfortunately the program Avas limited to such in extent that concrete results are not possible of attainment under the provisions of existing legislation; and Whereas the Congress now finds it is in the national interest to demon- strate, with the least possible delay, in actual production tests the several optimum aspects of the construction, operation, and main- tenance of sea water conversion and brackish water treatment plants: Now, therefore, be it Resolved by Me Senate and House of Representatives of the Tinted States of _°lnieriea. in Congress asse?n.hled, That (a) the Secretary of saline water the Interior shall, pursuant to the provisions of the Act of July 3,research. 1952, as amended (42 IT.

Murdy, Jr. , information and quest- ionnaires regarding the proposed Saline Water Demonstration Plant authorized by Congress to be. built some place on the Pacific Coast. It would seem that we have plenty of Ocean Water and certainly plenty of electricity and fuel and furthermore we have a great need for the water because of the recent salt water intrusion which would put Huntington Beach in a highly qualified position . Five to ten acres of land will be required and a million gallons of water daily is expect- ed to be reclaimed and the other requirement is that it will be hopeful that someone will purchase the reclaimed water at a reasonable price, and according to' a statement made by the Southern California Water Co. , they would be interested in purchasing this water. It is my understanding that Huntington Beach might well qualify for this Saline Water Demonstration Plant, however; to progress further , this matter should be handled by City authorities, therefore I am turning over -all cor- respondence to you and will hope that the Mayor and City Council including the City Engineer will follow through and fill in the enclosed questionnaires. Yours truly, William Gallienne, Public Relations Director City of Huntington Beach fat OF T y� _ 41w \ ti UNITED STATES f 'A DEPARTMENT OF THE INTERIOR OFFICE OF THE SECRETARY � i�Q WASHINGTON 25, D. C. 9. Dear Mr. Galli erne: This letter is in reply to your wire of March 11, in which you express a desire for establishing a, seawater conversion demonstration plant on the coast of California. Our Office of Saline Water has prepared a list of factors that are important in site selection. Two copies of this site location form are enclosed. These should be completed and one returned directly to the Office of Saline Water. The site selection depends to a large extent on the process.

Box 272 Huntington Beach, California Dear Mr. Gallienne: The purpose of this letter is (a) to acquaint you with a Federal law providing for a demonstration sea-water conversion plant to be built on the west coast, (b) to inquire into your interest in having the plant located in your city, and (c) to request completion and return of the enclosed form titled . "Data for Use in Selecting Site for Sea-Water Conversion Plant in California, to be Built Under Federal Law 85-883", in the event you would like yout. city considered for the plant. This form is to be used in evaluating propsective sites for the .plant in various California coastal cities and communities. Details relating to the background of the plant and the site survey which we are conducting are given below. In 1952 Congress passed the Saline Water Act, which provided for research into and development of practical means for the economical production from sea or other saline waters, . of water suitable for domestic, industrial, agricultural, and other beneficial uses. To carry out the purposes of the law, the Office of Saline Water in the Department of Interior was set up, the Director of which reports to the Assistant Secretary for Water and Power Development. In 1955 the Act was amended to broaden its provisions, extend the authorization period from five to ten years (to 1963) , and increase the funds authorized from $2,000,000 to_ $10,000,000. The Act contains a provision permitting the Office of Saline Water to cooperate with states and public agencies and Mr. William Gallienne -2- March 13, 1959 since California has 'a keen interest in salt-water conversion a cooperative agreement was entered into in April, 1958, between the' State of California, through this Department, and the Federal Government for mutual- assistance and exchange of information on the problems of salt-water conversion. We have since been work- ing closely with the Office of Saline Water on matters of mutual interest, including making a contribution of $40,000 toward an - engineering study of a conversion plant powered by a nuclear reactor. In September, 1958, Public Law 85-883 was enacted. This law, supplementary to the original Act of 1952, .provides for the construction of not less than five saline-water conver- sion plants in the United States, of which at least one plant is to be located on the west coast. A copy of the law is enclosed. The purpose of the law is to accelerate the development of a practical and economically competitive process for converting saline water into fresh water by constructing and operating a number of fairly large plants in various parts of the United States. Since California is threatened with water shortages in many areas, we hope that the west coast plant will be assigned to this State, probably at some coastal site between San Francisco and San Diego. The decision as to the site and type of plant will be made by the 'Secretary of the Interior. The Director, Office of- Saline Water, has requested this Department to assist him in obtaining and evaluation infor- mation on prospective sites in. California, in furtherance of our cooperative agreement mentioned above. . To aid in evaluating possible sites various data are required and to simplify the furnishing of such data a form is enclosed, listing the items considered important in selecting a site. The form is based upon one prepared by the Office of Saline Water but modified, princi- pally with respect to certain data called for in the Office of Saline Water form which can readily be furnished by the State and hence are omitted in the form enclosed. We are sending this letter to various counties, cities, and communities along the coast which we think may be interested in having the plant. After receipt of the completed forms, we will forward them to the Office of Saline Water with our -recommendations. The plant will probably be of the distillation type, with a capacity_ of not less than one million gallons per day of - high purity water suitable for municipal, industrial, or agricul- tural uses. While the primary purpose in building the plant is to determine the engineering and economic potentials of a partic- ular process, and to obtain design, operating, and cost data for use in the design of future large plants, it is desirable that there be a genuine need, either now or in the near future, for s Mr. William Gallienne -3= March 13, 1959 supplemental water in the area being served. It should be pointed out, however, that the output of the plant cannot. be considered as a firm supply .since testing and experimentation will be carried on for a period of several years. As a general guide in selection of a plant site, the following characteristics are desirable: 1. Location in a city or community having a well- developed water system of several million gallons-per- day capacity. 2. Location. close to an unpolluted source of undiluted sea water, preferably a channel, in which an intake structure could bonveniently be located. 3. Location reasonably close to an existing reservoir or water main to receive the demineralized water. 4. Good foundation conditions for construction. 5. Conveniently accessible. 6. Availability of adequate power supply at a reasonable distance. 7. Availability of fuel supply of gas or oil. It will be noted in Section 4 'of the law that the authority of the Secretary of the Interior to operate the plant will terminate in seven years, after which he shall dispose of the plant to the highest bidder or as otherwise directed by Act of Congress. Attention is also invited to Section 3 which permits the Secretary to accept financial and other assistance from any state or public agency in connection with activities relating to saline-water conversion. It is expected that the State will contribute a substantial sum to the construction and support of the plant. Any assistance, such as a direct financial contribution or land for the site, which the city or community interested in the plant desires to offer, will be welcome. If you should like to have the area or governmental unit which you represent considered for location of a plant as covered by Public Law 85-883 and as above described, please com- plete and return two copies of the enclosed form, adding any other information, such as photographs, which you think will be of value in deciding upon an appropriate plant site. We should 1 1 Mr. William Gallienne -4- March 13, 1959 particularly like to have a copy of any industrial survey report that has been made covering your community. If you have more than one site to recommend, please submit a completed form in duplicate for each site. If you have any questions or need any assistance in filling out the form, we shall be glad to assist you. It will be appreciated if you will return the form by April 15, 1959. If you have prepared a brochure describing the water supply conditions of your city, we would be pleased to receive it in addition to the completed form. If you are not interested in having the plant built in your community, we should appreciate your so advising us. Ver truly yours HARVEY 0. BAN . Director Enclosures : 1. Public Law 85-883 2.
