Potable Water Treatment
ZG S 820is a special resin, it is a macromolecule copolymer with activate rare earth elements on its styrene-DVB matrix. This kind of chemical structure is easy for arsenic in water to form stable complex compound, thereby to reduce arsenic density in water, in the end reach to the National Drinking Water Standard: arsenic less than 10mcg/L.
ZG S 820has comparatively higher adsorbent capacity and faster adsorbent speed to arsenic. It could reduce arsenic in solution efficiently, and reach to the safety standard. Moreover, it could use NaOH as eluent media to wash and recovery As（Ⅲ）completely, also, the resin could be used again after regenerate.
