Specialty Ion Exchange Resin for Phosphate Removal/Separation

PRODUCT DATA SHEET:

KP-304 is an ion exchange resin synthesized with special technology, specializing in removing phosphate 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-304 performs high selectivity to free radicals of strong acids, regardless of other weak-acids radicals surround by. Considering the increasing order of affinity that its special functional groups avail to, KP-304 is designed in priority of removing phosphate ions as PO43-  with rather high exchange capacity, which is being widely applied within industrial sewage or wastewater treatment.
