Abstract

Salt removal from water by means of ion-exchange hollow fibers was investigated under different conditions. The efficiency of desalination of tap water improves with increasing water velocity up to an optimal value in a concentration range of 0.2-0.3 N of the regenerants. Further improvement was obtained with a mixed cation- and anion-exchange hollow-fiber unit. A pilot plant which includes 25 m2 of ion-exchange hollow fibers was put in operation in combination with a conventional ion-exchange unit for salt removal from tap water. Regenerants rejected from the conventional ion-exchange unit are recycled for regeneration of the ion-exchange hollow fibers.
