Report that presents "information, findings, and recommendations concerning the multiple-effect falling-film-evaporation method of desalination" (p. 1).

Report presenting progress in saline water conversion at the Freeport Test Facility and Vertical-Tube-Evaporator Test-Bed Plant in Freeport, Texas, and the economics of its operation. Includes information regarding the LTV multiple-effect evaporation method of desalination.

"This report presents the results of a study of the preliminary feasibility and economics of desalting brackish waters for municipal and industrial watter supply in candidate regions of West Texas" (p. ii).

Report issued by the Office of Saline Water over engineering studies on the long-tube vertical falling-film distillation process. As stated in the introduction, "it is the objective of this report to study the falling-film distillation and to prepare an engineering evaluation of the process and the design of major items of equipment, with particular emphasis upon improving production and operational reliability and upon reducing product cost" (p. 1). This report includes tables, and illustrations.

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.

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

From Introduction: "The first demonstration plant sponsored by the Office of Saline Water was located in Freeport, Texas, and came 'on stream" in 1961. The incoming sea water was deaerated since both Speller (6) and Uhlig (7) recognized that dissolved oxygen was usually the controlling factor in the corrosion of iron stream condensate at temperatures even as high 400 degrees F. The water was acidified prior to daeration with H2SO4 to decompose the carbonates which subsequently would cause scale when the water was heated. After the carbonates were removed, the pH was raised to the neutral point, again to provide a less corrosive environment."

From Introduction: "The Sixth Annual Report presents a wide variety of information findings and recommendations concerning the Multiple-Effect VTE evaporation method of desalination. The included data are derived from the results obtained from operation, maintenance, and development studies conducted for the the U.S. Department of the Interior, Office of Saline Water, at Freeport, Texas. Not only are the technical, logistical, and economical evaluations for the Fiscal Year 1967 operations presented herein, but also the process and mechanical development program results as related to the process in particular, and desalination in general."
