Special Ion Exchange Resin for Wastewater Strong Acids
Halogen Bromate Ions(Br-, BrO3) Removal


KP-309 is an ion exchange resin synthesized with special technology, specializing in removing bromate anions of heavy metal salts. 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-309 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 that its special functional groups avail to, KP-309 
is designed specifically in removing bromate ions as Br– or BrO3– within industrial wastewater treatment.
