Distilled water. Distilled water is water that has been boiled into vapor and condensed back into liquid in a separate container. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container. Thus, distilled water is a type of purified water.
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.
It operated continuously for 40 years and distilled an average of 22.7 m 3 of water a day using the effluent from mining operations as its feed water. [4] Solar desalination in the United States began in the early 1950s when Congress passed the Conversion of Saline Water Act, which led to the establishment of the Office of Saline Water (OSW) in ...
High grade water recycling. Wave-powered desalination. 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.
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.
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 ...
