Sea Change
Desalinated seawater�considered a novelty by the United States water treatment community just five years ago�is rapidly becoming a viable water resource in this country....
Tapping the Desert
As part of an effort to augment the limited supply of freshwater in El Paso, Texas, engineers and planners are eyeing a new source: desalinated water pumped from beneath the desert floor....
Advanced Seawater Desalination Plant
A project that will demonstrate an enhanced seawater desalination process that operates in combination with upgraded existing coastal power plants to meet part of the projected water needs...
Studies on Herbal Desalination
India has a rich background traditional technologies. Varahamihira, an omni talented scientist of A.D 505?587 in his treatise entitled Brihatsamhita, suggested the use of five herbs for...
Brackish Groundwater and Urban Runoff: Source of Supply or Source of Problems?
The Sweetwater Authority hopes to be less dependent on imported supplies in water-short years, and has a goal of developing several alternative sources, including local runoff, brackish...
Is There a Future for Desalting in Meeting California's Water Needs?
This paper addresses the potential role of desalting reclaimed, brackish, and sea waters for use in meeting California's water needs. Brief descriptions of sources and costs are included....
Two Options for Disposal of Desalination Reject Water
A major problem associated with the use of desalination plants for the production of fresh water is the disposal of the reject water. This water is typically double the salinity of the...
The Desalination Situation
Rapid growth is putting increasing pressure on water supplies in coastal communities. Conservation can only do so much, and providing new freshwater supplies is getting more expensive...
Environmental and Economic Feasibility of Water Supply Alternatives in Hawaii and California: Desalination, Water Marketing and Conservation
Increasing urban demand for potable water in Honolulu, Hawaii and Santa Barbara, California, jeopardizes scarce supplies. The objective of this analysis is to compare the costs and benefits...
Conceptual Design Analysis for Hybrid-Cycle OTEC Plants for Co-Production of Electric Power and Desalinated Water
Hybrid-cycle OTEC power plants are shown to be potentially the most flexible and cost effective in obtaining any specific mix of electrical power and desalinated water. This paper describes...
Membranes in Water Treatment
Membrane technology, using reverse osmosis to treat drinking water, is a promising alternative to conventional treatment. The method is now being used for desalination in a growing number...
Desalination of an Impounded Estuary
