Kev siv
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm PAC yog nws txoj kev ruaj ntseg, ua rau nws cov khoom siv txhim khu kev qha rau ntau yam kev siv. Nws yog muaj raws li ib tug daj los yog lub teeb daj, tsaus xim av thiab tsaus grey resinous khoom. PAC muaj kev sib txuas zoo heev thiab adsorption zog, uas tuaj yeem tshem tawm impurities hauv dej. Thaum cov txheej txheem hydrolysis, lub cev thiab tshuaj hloov pauv xws li coagulation, adsorption, thiab nag lossis daus tshwm sim. Sib txawv ntawm cov tshuaj inorganic coagulants, cov qauv ntawm PAC yog tsim los ntawm polyhydroxy carboxyl complexes ntawm ntau yam duab, uas yuav ua tau sai flocculated thiab precipitated. Muaj feem xyuam rau ntau yam ntawm pH qhov tseem ceeb, tsis muaj corrosion rau cov khoom siv hauv cov kav dej, thiab kev ua kom huv dej zoo kawg nkaus. Nws tuaj yeem tshem tawm chroma, tshem tawm cov khib nyiab (SS), tshuaj lom neeg cov pa oxygen xav tau (COD), cov pa oxygen xav tau (BOD) thiab cov hlau hnyav xws li arsenic thiab mercury hauv dej. Qhov no ua rau PAC yog ib qho khoom tseem ceeb hauv cov dej haus, dej haus thiab dej phwj kho.
