  2. Desalination - Wikipedia

    en.wikipedia.org/wiki/Desalination

    Desalination is currently expensive compared to most alternative sources of water, and only a very small fraction of total human use is satisfied by desalination. [42] It is usually only economically practical for high-valued uses (such as household and industrial uses) in arid areas.

  3. Desalination by country - Wikipedia

    en.wikipedia.org/wiki/Desalination_by_country

    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). [112]

    Floating desalination. Desalination barges have operated since 2008 to meet high seasonal demand for potable water along the Red Sea coast of the Kingdom. In 2010 the largest floating desalination plant in the world, with a production capacity of 25,000 m3/day (9 million m3/year), was launched on a barge in Yanbu. It is sufficient to supply a ...

    The first modern large-scale desalination plant was the Perth Seawater Desalination Plant, completed in November 2006 and over 30 plants are currently operating across the country. Many plants are utilizing nearby wind or wave farms to use renewable energy and reduce operating costs, and solar powered desalination units are used for remote ...

  6. 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.

  7. Solar desalination - Wikipedia

    en.wikipedia.org/wiki/Solar_desalination

    Single phase desalination is predominantly accomplished with photovoltaics that produce electricity to drive RO pumps. Over 15,000 desalination plants operate around the world. Nearly 70% use RO, yielding 44% of desalination. [38] Alternative methods that use solar thermal collection to provide mechanical energy to drive RO are in development.

  8. Geothermal desalination - Wikipedia

    en.wikipedia.org/wiki/Geothermal_Desalination

    Geothermal desalination refers to the process of using geothermal energy to power the process of converting salt water to fresh water. The process is considered economically efficient, and while overall environmental impact is uncertain, it has potential to be more environmentally friendly compared to conventional desalination options. [1]

  9. Microbial desalination cell - Wikipedia

    en.wikipedia.org/wiki/Microbial_desalination_cell

    A microbial desalination cell (MDC) is a biological electrochemical system that implements the use of electro-active bacteria to power desalination of water in situ, resourcing the natural anode and cathode gradient of the electro-active bacteria and thus creating an internal supercapacitor.
