Report containing the summation of the desalination studies carried out by The University of Oklahoma Research Institute, including their theories of carbon demineralization, electrode development, and the cost estimates for a demineralization plant.

From Introduction: "The principal objective of this investigation is to promote fundamental understanding of the mechanism of solidification of aqueous solutions, and the effects of externally applied electrical and magnetic fields on solidification."

From Introduction: "This report explores the theory of the salt build-up phenomenon in a preliminary way. Several simplifying assumptions will be made, since the purpose is to obtain only approximate estimates of the importance of the phenomenon described."

From Introduction: "Progress of research related to problems encountered in processes for desalination by freezing is summarized in this report, which is the first annual progress report called for under the terms of Grant 14-01-0001-295 made to the Massachusetts Institute of Technology by the Office of Saline Water in 1962."

From Introduction: "The purpose of this study was to investigate analytically the performance of various combination heat and work-input MPE desalination systems ranging from pure heat-input to pure work-input types. MPE desalination systems are described in the following section, while, the analytical methods and discussions of the results obtained are presented in the appendices."

Report issued by the Office of Saline Water over studies conducted on by-products of saline water conversion plants. As stated in the introduction, "the objective of the survey has been to determine whether recovery of salable by-products from minerals present in saline waters offers a practical route to reducing the overall cost of converting these saline feeds to fresh water, and to delineate areas for further research and development on recovery processes" (p. 1). This report includes tables, and illustrations.

From Introduction: "This report describes the design, construction, operation, and maintenance of a particular solar still that has been shown to be a practical for converting saline water to fresh water at low cost in localities where there is a reasonable amount of sunshine. A series of photographs is included which illustrate the steps in constructing a still."

Report regarding the construction and testing of a sea water to fresh water conversion plant which uses a freezing method to remove salt. The report also presents information regarding the plant's economic and technical feasibility.

From Introduction: " With the ultimate objective of improving the process, a study of the mechanism(s) of material transport across the membrane was undertaken; the OSW sponsored a fundamental program of investigation of the Reverse Osmosis Process. Following a brief review of the results of the first year's investigations, the body of this report will cover the accomplishments of the second year's effort."

From Introduction: "In this report we will present the results of extending our study of MPE desalination systems to include freezing processes."

Report presenting a comprehensive bibliography on dropwise condensation that has been created as part of a study on the dropwise condensation characteristics of inorganic hydrophobic systems.

From Summary: "This report is concerned with specifying the heat transfer performance of a liquid-liquid spray tower and with determining if the performance can be augmented with electrohydrodynamic (EHD) means by reducing the drop size."

From Introduction and Summary: "This report presents the results of one year of experimental work performed under an Office of Saline Water Grant to study various aspects of the hydrate process for demineralizing sea water. Work is continuing on all phases of the subjects reported here."

From Introduction: "This Annual Report on the maintenance and operation of Brackish Water Conversion Demonstration Plant No. 3, located in Webster, South Dakota, presents the Plant Maintenance and Operational History and the Technical, Economic and Administrative evaluations of the Plant's operation during the period 1 July 1963 through 30 June 1964. This Report is prepared in compliance with Management and Operations Contract No. 14-01-001-225 dated 2 October 1961."

Report issued by the Office of Saline Water over engineering studies on the long-tube vertical falling-film distillation process. As stated in the introduction, "it is the objective of this report to study the falling-film distillation and to prepare an engineering evaluation of the process and the design of major items of equipment, with particular emphasis upon improving production and operational reliability and upon reducing product cost" (p. 1). This report includes tables, and illustrations.

From Introduction: "The investigation of solar distillation described in this Summary Report is part of the wide-ranging program of the Office of Saline Water to develop economical processes for the conversion of saline water to fresh water." From Summary: " Since the submission of the Summary Report which covered the first two years' progress, several new stills have been constructed, including four basin-type stills for the evaluation of basin liners and other materials."

Report issued by the Office of Saline Water over studies on seawater degasification with a focus on desorption of oxygen and carbon dioxide. The results are presented and discussed. This report includes tables, illustrations, and photographs.

From Introduction: "The major difficulty in interpreting the results obtained by this simple experimental technique is the specification of the temperature at the crystal-liquid interface. Since, the liquid-to-solid transformation is exothermic the temperature in the vicinity of the interface will exceed the temperature in the vicinity of the interface will exceed the temperature of the bulk of the cooling bath, which is the quantity most conveniently measured and most frequently reported."

Report documenting the ongoing progress and economic concerns of Saline Water Conversion Demonstration Plant No. 1 in Freeport, Texas.

Report documenting the ongoing progress and operations of the saline water conversion demonstration plant in San Diego, California.

From Background and Summary: "This report presents a theoretical and experimental study of techniques to improve thin-film evaporation with the use of fluted aluminum tubes."

From Abstract: "Activity coefficients of calcium sulfate were calculated from solubilities of gypsum in 0 to 1.0m sodium chloride at temperatures from 25 degrees C to 95 degrees C. X-ray diffraction studies for calcium sulfate modifications before and after contact with aqueous and saline solutions are given."

Report concerning the efforts to make the sea water distillation process more economical by improving the heat transfer surface. The General Electric wiped film process is one such improvement and is discussed along with its history, description, and related testing.

Report issued by the Office of Saline Water over studies conducted on electrosorption and desorption processes used for water desalination. The process and methods are presented and discussed. This report includes tables, illustrations, and photographs.
