Report issued by the Office of Saline Water over studies conducted on reverse-osmosis plants. The results of the studies are presented and discussed. This report includes tables, and illustrations.

From Forward: "This is one of a continuing series of reports designed to present accounts of progress in saline water conversion and the economics of its application. Such data are expected to contribute to the long-range development of economical processes applicable to low-cost demineralization of sea and other saline water."

From Summary, Conclusions, and Recommendations: "The operation and development programs carried out in the CEP, E-1A and LMC plant during the period July 1, 1970 to December 31, 1970 are described in this report. Data was developed on several development tasks as follows. A summary is presented of material evaluation studies made over the past three and a half years. Data on the experiences with coatings, mortar linings, elastomers, and nonferrous and ferrous metals are included. Details are presented of coatings and linings installed in the CEP II Effect including methods of surface preparation and costs."

From Introduction: "This report covers the activities by Catalytic, Inc., during the contract period from June 1, 1969 to June 30, 1970, a thirteen month period."

"A study was conducted to (a) investigate the effects of soil surface conditions on one-pass drawbar pull capabilities of a wheeled vehicle, (b) relate optimum drawbar pull to soil strength as measured by several instruments, (c) develop tentative equations for predicting optimum tractive coefficient, and (d) determine effects of tire characteristics (tread pattern and deflection) on drawbar pull. One hundred and six drawbar pullslip tests were conducted with a 3/4-ton M37 truck at a gross weight of 7240 lb. One tire size (9.00-16, 8-PR), two tread patterns (smooth and nondirectional military), and two tire deflections (15% and 35%) were tested. Surface conditions varied from dry and firm, to wetted with small amounts of water, to flooded. Asphalt surfaces also were tested" (p. xi).

From Summary: "The transport-depletion data obtained by the Southern Research Institute and by the Bureau of Reclamation at Denver, Colorado and at Webster, South Dakota, was reviewed. This data review made it possible to develop a design methodology for the pilot plant, and to identify the additional data required to adequately predict the performance of a transport-depletion stack."
