Abstract
1389530 Ion exchange water softeners STANDARD TELEPHONES & CABLES Ltd 12 July 1973 33184/73 Heading C1C [Also in Division C7] Fungal and bacterial growth in ion exchange resin water softeners is prevented by including an electrolysis cell in the water inlet, in which, when said resin is regenerated by flushing with an aqueous solution of NaCl the cell is energized so that electrolysis takes place to produce sodium hypochlorite in an antiseptic concentration.
