Regenerant:8 - 12% NaCl

DOWEX HCR-S/S is a strong acid cation exchange resin with gaussian (conventional) particle size distribution. Like DOWEX HCR-S, it is based on a styrene-divinylbenzene copolymer matrix with sulfonate functional groups. The 7% divinylbenzene content yields a resin with good capacity and highly efficient regeneration. DOWEX HCR-S/S resin is used in home water softeners. It can operate over the entire pH range under high flow rate conditions and at high temperatures. The high regeneration effectively minimizes the salt usage.
