Macroporous Polyacrylic Strong-Base Anion-Exchange Resin for NOM Removal
PRODUCT DATA SHEET:
KP-D730 is a macroporous strongly alkaline anion-exchange resin, with polyacrylic matrix crosslinked with divinylbenzene(DVB). By its specially-developed polymer structure and functional groups, KP-D730 outperforms other models at exchanging large amounts of organic matters, with the general adsorption rate up to 80~95% and elution rate over 95%. Taking advantage of its excellent removal of organic matter, efficient regeneration as well as good resistance to organic fouling, KP-D730 can compete and replace the common-used activated carbon granule(ACG) to decolorize and refine some transparent colored liquids, and also to remove natural organic matter(NOM) from aqueous solutions, for its superiority of low treatment cost, easy-regeneration, and essentially for its eco-friendly feature. The principle applications of KP-D730 mainly include yet not limited to organic scavenger, organics removal or TOC/Tannin removal, and free acids and alkali radicals if any. Hereby it has been widely applied in various industries, mainly serving the water-treatment engineering of surface water, groundwater, lake &river or infiltration-wells, or drinking water, and also the demineralization, decolorization &deodorization process in F&B, and more alike.
