  2. Slingshot (water vapor distillation system) - Wikipedia

    en.wikipedia.org/wiki/Slingshot_(water_vapor...

    Slingshot. Slingshot is a water purification device created by inventor Dean Kamen. [1] Powered by a Stirling engine running on a combustible fuel source, it claims to be able to produce drinking water from almost any source [2] by means of vapor compression distillation, [3] requires no filters, and can operate using cow dung as fuel.

  3. Solar still - Wikipedia

    en.wikipedia.org/wiki/Solar_still

    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. This makes them ideal for use in rural areas or developing countries where access to clean water is limited.

  4. Solar desalination - Wikipedia

    en.wikipedia.org/wiki/Solar_desalination

    Water production is proportional to the area of the solar surface and solar incidence angle and has an average estimated value of 3–4 litres per square metre (0.074–0.098 US gal/sq ft). [2] Because of this proportionality and the relatively high cost of property and material for construction, distillation tends to favor plants with ...

  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 them. Some of the water evaporates, and this steam flows into the tubes of ...

    en.wikipedia.org/wiki/Atmospheric_water_generator

    State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.

  7. Vacuum distillation - Wikipedia

    en.wikipedia.org/wiki/Vacuum_distillation

    Vacuum distillation or distillation under reduced pressure is a type of distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in their boiling points.
