Txiv maj phaub plhaub tshuab txais carbon rau kev kho dej yog tsim los ntawm cov txiv maj phaub plhaub thiab ua kom zoo los ntawm kev ua kom lub zog. Cov khoom lag luam tau tsim cov qauv pore, loj tshwj xeeb thaj chaw, muaj zog adsorption muaj peev xwm, muaj zog txhua yam thiab siab purity. Nws yog tsuas yog siv rau kev ua kom huv ntawm cov dej haus, cawv, dej haus thiab lwm yam khoom siv raw.
Txiv maj phaub plhaub activated carbon kuj tseem siv tau rau kev tshem tawm cov teeb meem impurities nyob rau hauv cov organic thiab inorganic tshuaj nyob rau hauv electroplating da dej. Nws muaj kev ua tau zoo heev rau kev lim dej haus. Nws tsis tsuas yog tshem tawm tsw, tab sis kuj txo COD, chromaticity thiab siab tshem tawm tus nqi ntawm ntau yam impurities xws li chlorine, phenol, mercury, lead, arsenic, detergents thiab tshuaj tua kab hauv dej.
