Abstract

Water is demineralised by first feeding it into a cation resin exchange bed and subsequently through a bed containing at least a part mixture of anion exchange resin and a highly acid cation exchange resin, in the stages: separation of cation exchange resin of the bed, treatment with regenerating acid, in series, firstly so freed cation exchange resin and subsequently with the same regenerating acid the first cation exchange resin, regeneration with alkali the freed anion exchange resin, rinsing the regenerating media from these resins and, subsequent to rinsing, mixing the earlier freed anion- and cation exchange resins to form the mixed resin bed for further treatment of the water.
