Report containing history, maintenance, and repairs of the Webster, South Dakota, test bed plant as well as reviews of optimization tasks performed therein.
Chamber Geometry in Multi-Stage Flash Evaporators
Report regarding "the importance of various parameters on the length of a typical stage in a multi-stage sea water flash evaporator" (p. 1). Parameter values were examined to determine their influence on chamber length.
Demineralization of Saline Water Through Pressurization Cycles with Ion Exchange Materials
Report regarding experiments to ionically desalinate water. Includes experimental procedures, interpretations of data, and a discussion of results.
Desalination by Electrosorption and Desorption
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.
Development of Economical Methods of Boron Removal From Irrigation Return Waters
Report that examines a method for reducing the boron levels of irrigation return waters to nonphytotoxic levels.
Economic and Technical Evaluation of the Wiped Film Evaporator
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.
The Economics of a Regional Municipal Desalting System in the Lower Rio Grande Valley of Texas
Report containing the results of a study of the costs of a large-scale desalting system that served an inter-municipal area in the Lower Rio Grande Valley in Texas.
Investigation of the Availability of Geothermal Energy for the Demineralization of Saline Water
From Introduction: "The purpose of this investigation was to examine the question of the availability of geothermal energy and in particular the availability of geothermal energy from the Black Hills of South Dakota.
Investigation of Thermal Diffusion for Saline Water Conversion
From Introduction: "The following sections treat in detail each of the three major phases of this investigation: ordinary diffusion coefficient studies, thermal diffusion coefficient studies, and packed thermogravitational column studies. This report is concluded with a summary of the progress achieved and a discussion of areas for future investigation."
Saline Ground-Water Resources of the Tularosa Basin, New Mexico
From Abstract: "This report describes the location, extent, and quality of saline ground water in Tularosa Basin, a north-trending elongated, intermontane, desert basin in south-central New Mexico."
Scale Control With Graphite Heat-Transfer Tubes of Controlled Permeability to Steam
From Introduction: "The present project authorized under OSW Contract No. 14-01-0001-685 was undertaken to investigate the feasibility of controlling calcium sulfate scale by permission of condensate through graphite heat-transfer tubes. Specifically, the following tasks were accomplished during the course of this contract: Graphite tubes 108" long X 2" O.D. x 1 1/2" I.D. were manufactured at three permeability levels. A test apparatus was constructed and proved out as a useful and reliable probe. Tests were conducted at two brine concentrations. Some correlation of test considerations with scale formation was found. The economic practicality and the feasibility of using permeable tubes for desalinization were established."
Second Two Years' Progress on Study and Field Evaluation of Solar Sea-Water Stills
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."
Theoretical Studies of the Behavior of Ions in Aqueous Solutions of Mixed Electrolytes With Respect to Osmionic Cell Operation
From Forward: "This is the seventy-sixth of a series of reports designed to present accounts of progress in saline water conversion with the expectation that the exchange of such data will contribute to the long-range development of economical processes applicable to large-scale, low-cost demineralization of sea or other saline water."
Thermodynamic Properties of Saline Water
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."
