electrodialysis

(ē-lĕk″trō-dī-ăl′ĭ-sĭs) plural.electrodialyses [″ + dia-, apart, + lysis, dissolution]
A method of separating electrolytes from colloids by passing a current through a solution containing both. A semipermeable membrane is usually used to aid in the separation, with one electrode on each side.

We're doing research on a process called electrodialysis, which is much less energy intensive, and a reverse osmosis process mainly using membranes, so the energy required is much lower.
