Answer :

Electrodialysis: 

Description: Electrodialysis is a method in which ions are pulled out of the salt solution by passing direct current using electrodes and thin rigid plastic membrane pair (natural or synthetic). An electrodialysis cell consists of a large number of paired sets of rigid electrically charged plastic membranes. Salt water is passed under a pressure of about 5-6kgf /cm2 between membrane pairs and an electric field is applied perpendicular to the direction of water flow. When direct electric current is passed through the salt solution, ions are separated and they started moving towards oppositely charged electrode through the membrane.
