Purpose and Scope: "The purpose of this study is to provide basic water supply data needed for future evaluation and selection of promising saline water conversion opportunities. This report presents information regarding the present and future supply situation of individual communities. Also presented is information on regional water plans with respect to provisions for municipal water supply."

Report concerning manufacturing variables on sulfonated polyphenylene oxide reverse osmosis membranes. The effects these variables have membrane performance are discussed as well as procedures to increase membrane reproducibility and performance.

Report issued by the Office of Saline Water over studies conducted on the reverse-osmosis program. The methods of desalination through osmosis are discussed. This report includes tables, illustrations, and photographs.

From Introduction: "This report includes the sixth segment of a continuing effort begun early in 1963. Purpose of the work is the scale-up of reverse osmosis from a laboratory curiosity to an economical system for the production of potable water from salty feeds."

From Introduction: "This report covers the operation at Webster, South Dakota of an Aerojet Model 1-56OB-2 reverse osmosis (RO) unit purchased by the office of Saline Water (OSW) from Aerojet-General Corporation under Contract 14-0100001-1112."

Report concerning the development of equipment and processes required for the production of porous wall reverse osmosis tubes lined with membrane material deposited by extrusion. These include a chilled water membrane gellation system, "a heat treat fixture permitting simultaneous heat treatment of several reverse osmosis tubes" (p. 1), and the optimization of the structure of fiberglass filament/resin composite material.

Report concerning the relative costs of providing water via an electrodialysis-based water desalination plant that was only to be operated during periods of drought.

Report presenting progress in saline water conversion at the Test-Bed Plant in Webster, South Dakota, and the economics of its operation.

From Introduction: "The principal objective of this study is to digest the experience accumulated in the operation of the demonstration plants, and from this information, to arrive at the cost of fresh water when produced on a large scale. It is important to recognize that the costs, as calculated in this report, are based upon the state of development of the processes as exemplified and proven in the demonstration plants. The field is new, and the rate of development is such that further cost reductions may be expected."

Report investing the "effects of contaminated raw water supplies on conversion processes," and studying "potential technical and economic advantages of combination saline water and sewage effluent conversion plants" (p. 1).
