- Research on Thermoelectric Heat Pumps
- From Results: "Prior to stating results achieved, let us first discuss the measurements we were able to make, and how these measurements might--or might not--be indicative of the objective we strove to reach. Tables I and II, and related Figs. 11 and 12, show the best results obtained. Final Columns of Tables I and II are believed to show, at least to a degree, how good or how poor our best sputtered films turned out to be, compared with top-quality Peliter semiconductor materials."
- Absorption-Multistage Flash Distillation Process
- "The major factors which influence the cost of water production from sea water by distillation methods are (1) the cost of fuel or energy required by the distilling plant, and (2) the required capital investment. Preliminary studies on the application of absorption or solution cycles to distillation methods for saline water conversion indicated that the fuel cost or thermal economy of a distillation plant could be improved by combining the distillation process with an absorption or solution cycle" (p. 1).
- The Mechanism of Desalination by Reverse Osmosis
- Report describing the various parameters operative in fabricating desalination membranes for the Reverse Osmosis Process and the mechanism of separation. The bulk of the membrane contains huge quantities of capillary water which permits the movement of water through the body of the membranes at extremely rapid rates, there being essentially no pressure drop in this portion of the membrane.

- Report presenting experimental results for the washing of brine from beds of small plastic and glass beads, and from beds of ice particles prepared by partial freezing of brine. The data are analyzed in terms of a longitudinal-dispersion model which describes the blending of water and brine at the moving wash-water "front".
- An Investigation of the Use of Acoustic Vibrations to Improve Heat Transfer Rates and Reduce Scaling in Distillation Units Used for Saline Water Conversion
- Report presenting a study to determine the feasibility of using acoustical energy to improve the economy of evaporator operation as related to saline water conservation. Some of the improvements to be sought are increased film heat transfer coefficients on the water side, possible promotion of dropwise condensation on the steam side, and reduced scale formation.
- Electrochemically Controlled Ion-Exchange
- "For the past several years, the Rocketdyne Research Division has, under the sponsorship of the Office of Saline Water, engaged in a study of the application of electrochemical techniques to the demineralization of brackish water. Early work in this program was concerned with a mechanistic study of electrochemically induced demineralization at chemically treated carbon electrodes. The results of this study led to the development of a process called electrochemically controlled ion-exchange" (p. 2).
