BRACKISH WATER DESALINATION USING TUNABLE ANION EXCHANGE BED

摘要

A process for treating feed water for desalination, the process comprising: (a) removing one or more polyvalent anions from the feed water by feeding the feed water into a bed comprising one or more anion exchange resins under conditions sufficient to exchange the polyvalent ions in the feed water with one or more monovalent anions in the resin; and (b) regenerating the bed by feeding a brine stream into the bed under conditions sufficient to exchange one or more polyvalent anions in the resins with one or more monovalent anions in the brine stream.
