Special Ion Exchange Resin for Wastewater Strong Acids
Halogen Chlorate Ions(Cl, ClO3) Removal


KP-302 is an ion exchange resin synthesized with special technology, specializing in removing strong acids radicals containing chlorinum. For its highly firm and solid structure, this resin performs with its high anti-osmotic efficiency and excellent mechanical &shock resistance as well as functions anti-pollution from organics. 

Owing to its special weak-base functional groups, KP-302 performs high selectivity to free radicals of strong acids, peculiarly with strong affinity to halogen anions such as fluorine, chlorine, bromine and iodine, etc. Considering the increasing order of affinity, KP-302 is designed specifically in removing chlorate ions as Cl–  or ClO3– within industrial wastewater treatment.
