The Electrodialysis Advantage | WWD

Electrodialysis, is a membrane separation process in which ions are transported through semipermeable membranes under the influence of an electric field from one solution to another in order to reduce the ionic content of water. The ,electrodialysis, stack is composed of alternately constructed cation and anion exchange membranes to form dilute and concentrate chambers.
