Specialty Special Ion Exchange Resin for
Wastewater Weak Acids
Halogen Fluorinion(F-) Remova


KP-208 is an ion exchange resin synthesized with special technology, specializing in removing Fluorinion. 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 strong-base functional groups, KP-208 performs strong adsorbability to free radicals of both strong and weak acids, peculiarly with mighty affinity to halogen anions such as fluorine, chlorine, bromine and iodine, etc. Considering the increasing order of affinity that its functional groups avail to, KP-208 is designed specifically in removing weak acid radicals fluorinion(F) within industrial wastewater treatment.
