Desalination is a process that removes mineral components from saline water. More generally, desalination is the removal of salts and minerals from a substance. [1]
Vacuum distillation is often used in large industrial plants as an efficient way to remove salt from ocean water, in order to produce fresh water. This is known as desalination. The ocean water is placed under a vacuum to lower its boiling point and has a heat source applied, allowing the fresh water to boil off and be condensed.
California authorities have conditionally approved a controversial desalination plant in a small city with many low-income families in Monterey Bay.
Distilled water is also used for drinking water in arid seaside areas lacking sufficient freshwater, via desalination of seawater. [16] Health effects
Poseidon Water is seeking $1.1 billion from the state to build a controversial desalination plant in Huntington Beach.
In the days that followed, rapid desalination of sea water from 14 to 4ppm was discovered in the waters near Odesa, Ukraine. In some coastal areas, researchers noted acute toxicity in the water, with nitrogen concentrations drastically rising, an indicator of direct sewage pollution. Polluted water was also found in the Danube River. [8]
The heat added in the brine heater usually comes in the form of hot steam from an industrial process co-located with the desalination plant. The steam is allowed to condense against tubes carrying the brine (similar to the stages). [citation needed] The energy that makes possible the evaporation is all present in the brine as it leaves the heater.
Particularly important are distillation (desalination of seawater) and reverse osmosis. Thermal Bringing water to its boiling point (about 100 °C or 212 F at sea level), is the oldest and most effective way since it eliminates most microbes causing intestinal disease, [ 19 ] but it cannot remove chemical toxins or impurities.
