Removal of Scale-Forming Compounds from Sea Water

Description: 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."

Operation of Pilot Plant LTV Evaporator at Wrightsville Beach, North Carolina

Description: From Introduction: "The primary objective in the development of the W. L. Badger Long Tube Vertical Multiple Effect Evaporator for saline water conversion is to minimize the ultimate cost of producing potable water. To accomplish the primary objective, it is necessary to (1) prevent formation of scale on heating surfaces, and (2) minimize corrosion to permit use of inexpensive materials of construction. The work done leading to this report was guided in the direction of accomplishing the two secondary objectives."

Description: From Abstract: "The Vacuum-Freezing Vapor-Compression (VFVC) Process was evaluated on high salinity brackish water during the period from February 1968 through December 1969 by Colt Industries Inc., under O.S.W. Contract No. 14-01-0001-967 at Roswell, New Mexico. The 15,000 gpd VFVC test plant is mounted on a mobile trailer which was built by Colt Industries Inc. in their factory at Beloit, Wisconsin. Prior to operation at Roswell, the plant was operated at Wrightsville Beach, North Carolina to check out the system and to operate the trailer on sea water." Process Description: "A simplified diagram, Figure 2, shows both the essential components of the process and flow paths of the various streams in the system. Typical heat and mass balances are shown on Figures 3 and 4."

Third Report on Horizontal-Tube Multiple-Effect Process Pilot Plant Tests

Description: From Summary: "This report describes the continuing work on HTME distillation plants, the first portions of which were reported in References 1 and 2. A major purpose in the testing of the three-effect pilot plant was to demonstrate mutiple-effect operability of the the horizontal tube method, when utilizing basically the same construction methods and materials as those proposed for commercial HTME plants."

Removal of Scale-Forming Compounds from Sea Water

Description: 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."

Third Annual Report: Brackish Water Conversion Demonstration Plant Number 4, Roswell, New Mexico

Description: 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."

Research on Thermoelectric Heat Pumps

Description: From Results: "Prior to stating results achieved, let us first discuss the measurements we were able to make, and how these measurements might--or might not--be indicative of the objective we strove to reach. Tables I and II, and related Figs. 11 and 12, show the best results obtained. Final Columns of Tables I and II are believed to show, at least to a degree, how good or how poor our best sputtered films turned out to be, compared with top-quality Peliter semiconductor materials."

Scale Control With Graphite Heat-Transfer Tubes of Controlled Permeability to Steam

Description: From Introduction: "The present project authorized under OSW Contract No. 14-01-0001-685 was undertaken to investigate the feasibility of controlling calcium sulfate scale by permission of condensate through graphite heat-transfer tubes. Specifically, the following tasks were accomplished during the course of this contract: Graphite tubes 108" long X 2" O.D. x 1 1/2" I.D. were manufactured at three permeability levels. A test apparatus was constructed and proved out as a useful and reliable probe. Tests were conducted at two brine concentrations. Some correlation of test considerations with scale formation was found. The economic practicality and the feasibility of using permeable tubes for desalinization were established."

Investigation of Membrane Stack Resistance Increase With a Natural Brackish Water

Description: 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."
