- 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 the next stage (effect), heating and evaporating more water. Each stage essentially reuses the energy from the previous stage, with successively lower temperatures and pressures after each one. There are different configurations, such as forward-feed, backward-feed, etc. Additionally, between stages this steam uses some heat to preheat incoming saline water. (en)
- Une distillation à multiples effets ou distillation à effet multiple est un procédé de dessalement de l’eau. La distillation à multiples effets et l'osmose inverse sont généralement considérés comme les procédés les plus économiques pour dessaler de l’eau de mer ou de l'eau saumâtre à l’échelle industrielle.
