Report presenting accounts of testing saline water conversion and the economics thereof. This report covers the fifteenth and sixteenth Development Runs, which evaluated the following: the performance of the plant's double-fluted tube bundle and titanium tube bundle; the condensate handling-restrictions in the 5 effect module; a sump to sump brine transfer system modification; porcelain spray nozzles; enhanced surface tubes; and an oxygen scavenging system.

From Introduction: "This report and the study which went into it form a part of the activities sponsored by the Office of Saline Water, U.S. Department of the Interior, in their accelerated program to develop large plants for the economical desalting of seawater."

Report issued by the Office of Saline Water over design studies for a 50 million gallon desalination plant. As stated in the introduction, "this report presents a conceptual design of a 50 MGD multistage flash plant and a conceptual design of a test module based on the 50 MGD plant design and proposed to demonstrate large plant design concepts. The report also includes a discussion of the more important engineering design studies employed in the development of the conceptual designs" (p. 1). This report includes tables, and illustrations.

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).

From Introduction & Scope: "This study was undertaken for the Office of Saline Water to determine the optimum brine heater outlet temperature in single-purpose sea water conversion evaporators for several fuel costs, based on balancing the increased performance ratio possible with high-temperature operations against the increased cost of pressure vessels, corrosion protection, and scale control."

Report presenting some of the progress made in saline water conversion so that the data can contribute to the long-range development of economical processes applicable to large-scale, low-cost demineralization of sea and other saline water.

From Introduction and Summary and Conclusions: "The disposal of the effluents from large desalination plants has been studied for two years by the Dow Chemical Company and Texas A. & M. University under contract to the Office of Saline Water. Recommendations are presented on the type, frequency, and intensity of pre-plant oceanographic and biological surveys and of post-plant monitoring and verification surveys."

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."

Report documenting the ongoing research and developments undertaken at a pilot plant with five vertical-tube evaporators.

Report concerning the possible use of octafluorocyclobutane, R-C318, being used in the direct freezing process as a means of extracting fresh water from sea water. Topics include using R-C318 to make ice, flash precooling, design of a small direct freezing pilot plant using R-C318, and related economic studies.

Report describing the application of conventional cost experience to physical features of source of supply, treatment, pumping, transmission, distribution, and storage for community water supply sources. Some costs due to readily removable water quality characteristics like suspended solids, color, taste, and order are measurable, as are other conventional costs of operation and maintenance. Other costs related to an excess of dissolved solids, however, tend to be unknown and are the subject of this study.

Report containing a design study of a 250 million gallons per day desalination plant. Contains a description of the desalination process, information regarding the design's efficiency, estimated capital and production costs

Report concerning "the development of techniques and mathematical models for an optimum design of a Vertical Tube Evaporator desalting plant." (p. 1)

From Forward: "This report presents the results of a study of the potential contribution of desalting to future water supply in the State of Texas."

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

From Abstract: "Primary interest was placed on the scale formation problem. Significant improvements were made in the process and described in this report. Maintenance requirements were unusually high during the year, primarily as a result of cumulative corrosion damage over the last three years. The most significant damage was in the circulating pumps, the heat exchangers and feed piping. These and other failures are described."

Report regarding the ongoing study of the removal of salt water scale formers using phosphate precipitation and lime-magnesium carbonate precipitation.

Report that includes results and methodology from an engineering study regarding drought in Northern New Jersey and New York City. Topics include the area's water systems, the possible integration of desalting plants, and the potential costs of such plants.

Report demonstrating the concept of a small and disposable reverse-osmosis cartridge. Research includes "1) a search for suitable membrane supporting structures and materials during which the hydrodynamic characteristics of a number of potential materials were evaluated, 2) the evaluation of reverse-osmosis membranes cast directly on support materials and on reinforcing materials, and 3) the design, fabrication and testing of a small reverse-osmosis cartridge" (p. 1).

Report issued by the Office of Saline Water over studies conducted on equipment needed at seawater distillation plants. Each equipment component is discussed in detail. This report includes tables, illustrations, and a photograph.

From Introduction: "An investigation was undertaken by the Bureau of Reclamation to identify the cause of causes of this problem with a particular brackish water. The resistance increase of is of great concern principally because of the increase in power consumption that ultimately contributes to a higher cost for product water. Reports show that membrane stack resistance has increased as much as 200 percent over period of several days."

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 studying the use of desalinated water for irrigation at three locations in Arizona and California. Costs and benefits are measured among several different areas, including multiple concentrations of desalinated water, different desalting methods, and the desalting process.

From Introduction: "The report describes the studies made on 20mgd desalting plants, a size that was selected based on recovering 3,000 tons per day of salt for feed to a chlorine-caustic plant that would be part of the Energy Center."
