Study Notes
- Desalination is the process of removing salts from water and is used in municipal, industrial, and commercial applications.
- Development of desalination technology began during World War II due to limited fresh water supplies and the passing of "The Saline Water Act" in 1952.
- The first seawater desalination demonstration plant in the United States was built in Freeport, Texas in 1961, producing 1 million gallons per day (mgd).
- Desalination technologies can be broadly classified into thermal and membrane types.
- Thermal technologies involve heating saline water to produce distillate, while membrane technologies use pressure to separate salts from water.
- As of early 2000, the global desalination capacity was about 7 billion gallons per day (bgd), with thermal processes accounting for 50% and membrane technologies for 50%.
- Desalination capacity increased by about 12% per year from 1972 to 1999 and there have been over 8,600 desalination plants installed worldwide, with approximately 20% in the U.S.
- Thermal desalination technologies involve heating saline water to produce distillate, but are rarely used for brackish water due to high energy consumption.
