A process that uses electrical current applied to permeable membranes to remove minerals from water. Often used to desalinize salty or brackish water.

water containing salt is placed between semipermeable membranes and a curent is applied. Cations and ions migrate in opposite directions and pass through the membranes, leaving purer water between the membrane filters.

Most of the impurities in water are present in an ionized (electrically-charged) state. When an electric current is applied, the impurities migrate towards the positive and negative electrodes. The intermediate area becomes depleted of impurities and discharges a purified stream of product water. This technology is used for brackish waters but is not currently available for desalting seawater on a commercial scale.
