ZGC 858 iron removing resin


“Hydrolite”ZGC 858 is a styrene-DVB crosslinked strong acid cation resin with inert core, shallow sulfonation shell structure. It is a high efficient iron removing, water softening resin. Due to the short spaces between functional groups, 90% functional groups distribute on the surface of resin beads, it helps resin with high exchange speed. All the exchange reaction happened on the surface of resin beads, no need to spread to the inside of resin. It avoids the leakage of ions and assures full regenerate.

Because of its special structure and unique physical and chemical properties, ZGC 858 is the best product to removing iron, calcium and magnesium in potable water.
