There are several available technologies for removing salt from a saline water. By far the most energy efficient is reverse osmosis
Get Price2014-12-18u2002·u2002Studies have shown variations in prices of desalinated water produced with conventional and renewable energy. Using conventional energy for desalination is most cost-efficient: $0.2–1.3/m 3 ($0.76–4.9/kgal) for desalinated brackish groundwater and $0.2–3.2/m 3 ($0.76–12.1/kgal) for desalinated …
Get PriceDesalination is a process that takes away mineral components from saline water. Due to its energy consumption, desalinating seawater is generally more costly than fresh water from rivers or groundwater, water recycling and water conservation. Saltwater is desalinated to produce water suitable for human consumption or irrigation.The by-product of the desalination process is brine.
Get Price2017-2-1u2002·u2002Process of Sea Water Desalination. Desalination, also popularly known as desalting, is the process of removing salt from the ocean water to convert it into a fresh water source. The water which is desalinated can be used for various purposes like drinking, industrial, commercial and agricultural use.
Get PriceThe water to be desalinated is heated at low pressure, which causes sudden, irreversible evaporation. This process is repeated in successive stages where the pressure decreases according to different conditions. It is suitable for waters of a high salinity or those of a higher temperature and greater pollution.
