Abstract
Abstract Up to the present time, the development of desalting technology has been mainly directed at water supply augmentation. In view of Federal and State legislation in the U.S.A. to support water pollution control and water quality improvement, along with advances in membrane desalting processes, an expanded new role for desalting is discussed. Potential desalting applications now under study by the Bureau of Reclamation's “Colorado River Water Quality Improvement Program” are examined along with general constraints, cost-effective criteria, planning strategies, and water resources impacts. Specific desalting sites and time frames are briefly addressed from a planning viewpoint generally limited to the upper region of the Colorado River Basin. Estimates of plant capacities, general feedwater conditions, costs, and various types of processes under planning investigation are provided. The paper suggests key areas of membrane desalting research needs related to salinity control. Finally, this planning overview concludes that the economic differences between conventional salinity control techniques and desalting may be narrowing.
