Specialty Resin for Wastewater Strong Acids Separation


KP-300 is a specialty wastewater treatment ion exchange resin synthesized with special technology. For its highly firm structure, it performs with excellent resistance to mechanical strength and osmotic shock as well as anti-pollution from organics. 

Owing to its special weak-base functional groups, KP-300 functions high selectivity to free radicals of strong acids only, regardless of other weak-acids radicals surround by. It also performs with high exchange capacity to halogen salts that include yet not limited to fluoride, chloride, bromide and iodide, etc. However, it is most widely being applied in adsorbing strong acid root anions such as chlorate, sulphate, nitrate and phosphate radicals from industrial wastewater or sewage prior to safe discharge.
