Abstract: The present invention describes a selective electrodialysis process for the retention of useful mineral ions in potable water obtained from desalination process. More particularly, the invention relates to selective electrodialysis of brackish and seawater to obtain potable water rich in useful constituents such as Ca2+, Mg 2+ , SO 4 2- , and HCO 3 - , while discarding much of the NaCI present in the feed water. Polyaniline (PANI)-modified ion exchange membranes are used for carrying out the claimed process.
