  2. Desalination - Wikipedia

    en.wikipedia.org/wiki/Desalination

    Improved desalination efficiency is a primary factor contributing to this reduction. Energy consumption remains a significant cost component, accounting for up to half the total cost of the desalination process. [105] Desalination can substantially increase energy intensity, particularly for regions with limited energy resources.

  3. Multi-stage flash distillation - Wikipedia

    en.wikipedia.org/wiki/Multi-stage_flash_distillation

    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.

  4. 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 them.

  5. Solar desalination - Wikipedia

    en.wikipedia.org/wiki/Solar_desalination

    RO is the most common desalination process due to its efficiency compared to thermal desalination systems, despite the need for water pre-treatment. [39] Economic and reliability considerations are the main challenges to improving PV powered RO desalination systems. However, plummeting PV panel costs make solar-powered desalination more feasible.

  7. Vacuum distillation - Wikipedia

    en.wikipedia.org/wiki/Vacuum_distillation

    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.

  8. Solar still - Wikipedia

    en.wikipedia.org/wiki/Solar_still

    Solar-powered desalination systems can be installed in remote locations where there is little or no infrastructure or energy grid. Solar is still affordable, eco-friendly, and considered an effective method amongst other conventional distillation techniques. Solar still is very effective, especially for supplying fresh water for islanders.

  9. Electrodialysis reversal - Wikipedia

    en.wikipedia.org/wiki/Electrodialysis_reversal

    Electrodialysis reversal (EDR) is an electrodialysis reversal water desalination membrane process that has been commercially used since the early 1960s. [1] An electric current migrates dissolved salt ions, including fluorides, nitrates and sulfates, through an electrodialysis stack consisting of alternating layers of cationic and anionic ion exchange membranes.
