  2. Desalination - Wikipedia

    en.wikipedia.org/wiki/Desalination

    The desalination process's energy consumption depends on the water's salinity. Brackish water desalination requires less energy than seawater desalination. [82] The energy intensity of seawater desalination has improved: It is now about 3 kWh/m 3 (in 2018), down by a factor of 10 from 20-30 kWh/m 3 in 1970.

  3. Multi-stage flash distillation - Wikipedia

    en.wikipedia.org/wiki/Multi-stage_flash_distillation

    Multi-stage flash distillation (MSF) is a water desalination process that distills sea water by flashing a portion of the water into steam in multiple stages of what are essentially countercurrent heat exchangers. Current MSF facilities may have as many as 30 stages. [1]

  4. Vapor-compression desalination - Wikipedia

    en.wikipedia.org/wiki/Vapor-compression_desalination

    Vapor-compression desalination (VC) refers to a distillation process where the evaporation of sea or saline water is obtained by the application of heat delivered by compressed vapor. Overview [ edit ]

  5. Multiple-effect distillation - Wikipedia

    en.wikipedia.org/wiki/Multiple-effect_distillation

    Multiple-effect distillation or multi-effect distillation (MED) is a distillation process often used for sea water desalination.It consists of multiple stages or "effects". In each stage the feed water is heated by steam in tubes, usually by spraying saline water onto th

    en.wikipedia.org/wiki/Reverse_osmosis

    Sea-water RO (SWRO) desalination requires around 3 kWh/m 3, much higher than those required for other forms of water supply, including RO treatment of wastewater, at 0.1 to 1 kWh/m 3. Up to 50% of the seawater input can be recovered as fresh water, though lower recovery rates may reduce membrane fouling and energy consumption.

    Another practice that is being considered closely is the process of desalination in order to achieve a more sustainable water supply from seawater. Although desalination also comes with environmental concerns, such as costs and resources, researchers are working closely to determine more sustainable practices, such as creating more productive ...

    Jul. 26—With approval of a $10 million Texas Water Development Board loan, the Laguna Madre Water District will build a 10 million gallon seawater desalination plant in Port Isabel using water ...

  9. Solar desalination - Wikipedia

    en.wikipedia.org/wiki/Solar_desalination

    The feed water passes in parallel through all the cells, providing a continuous flow of permeate and brine. Although this is a well-known process electrodialysis is not commercially suited for seawater desalination, because it can be used only for brackish water (TDS < 1000 ppm). [38]
