Reverse osmosis desalination plant in Barcelona, Spain. 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] One example is soil desalination. This is important for agriculture.
The country's desalination plant, opened in March 2003, is considered to be the first of its kind. It was the largest desalination facility in the Americas, and it processes 28,800,000 US gallons (109,000 m 3) of water a day at the price of $2.67 per 1,000 US gallons (3.8 m 3). [114]
Indirect solar desalination systems comprise two sub-systems: a solar collection system and a desalination system. The solar collection system is used, either to collect heat using solar collectors and supply it via a heat exchanger to a thermal desalination process, or to convert electromagnetic solar radiation to electricity using photovoltaic cells to power an electricity-driven ...
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.
Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane. Water produced by reverse osmosis may be used for a variety of purposes, including desalination, wastewater treatment, concentration of contaminants, and the reclamation of dissolved minerals. [1]
Solar desalination is a desalination technique powered by solar energy. The two common methods are direct (thermal) and indirect (photovoltaic). ... For example ...
In response to tightening supplies, urban water managers are turning to strict conservation measures and alternatives such as desalination and recycled wastewater to help keep taps flowing. But ...
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.
