Removal of Scale-Forming Compounds from Sea Water (open access)

Removal of Scale-Forming Compounds from Sea Water

From introduction: "In the process of being developed under Contract No. 14-01-001-202 fertilizer grade phosphoric acid (or sodium phosphates obtained from reacting phosphoric acid and sodium hydroxide or soda ash) is mixed with sea water. The subsequent addition of ammonia causes the precipitation of solids which are then allowed to settle from water. The resulting descaled sea water is now ready for utilization in a water recovering plant."

Investigation and Preparation of Polymer Films to Improve the Separation of Water and Salts in Saline Water Conversion (open access)

Investigation and Preparation of Polymer Films to Improve the Separation of Water and Salts in Saline Water Conversion

From Introduction: "As will be explained in more detail elsewhere in this report, casting methods and drying conditions have been found to have a drastic effect on film permeability to both water and salt. Errors that became evident in temperature control indicated that some of the previous high rates were obtained at temperatures considerably higher than the 100 degrees C that was intended and reported."

Removal of Scale-Forming Compounds from Sea Water (open access)

Removal of Scale-Forming Compounds from Sea Water

From Recommendations: "Laboratory research on the process for descaling sea water should be continued to improve the process and thereby lower the cost. Research efforts should be concentrated on methods for producing low cost sodium phosphates (needed for the precipitation of the scale-forming elements) from fertilizer grade phosphates and on increasing the crystalline nature of the phosphate precipitates (to reduce dewatering costs). The descaled sea water should be experimentally evaluated first in the laboratory and later under actual operating conditions so that its value to the water recovery program may be established."

Seawater Softening by Ion Exchange as a Saline Water Conversion Pretreatment

From Introduction: "A pilot plant embodying these ideas, in an unusual method of softening, was designed and constructed by the Texas Division of The Dow Chemical Company. Two 4,000 gallon per day vapor compression evaporators were furnished for the testing program bu the Bureau of Yards and Docks of the United States Navy. This report summarizes the results of the testing program."
