Poly Aluminium Chloride/PAC muaj cov yam ntxwv ntawm kev nqus, kev sib sau ua ke, thiab nag. Nws tsis ruaj khov thiab tsis xeb. Yog tias nws tsis tau txau rau ntawm daim tawv nqaij, nws yuav tsum tau yaug nrog dej tam sim ntawd. Cov neeg ua haujlwm tsim khoom yuav tsum hnav khaub ncaws dav dav, lub ntsej muag, hnab looj tes, thiab khau roj hmab. Poly Aluminium Chloride/PAC muaj qhov zoo ntawm kev ruaj khov zoo ntawm kev txau kom qhuav, kev hloov pauv dav rau thaj chaw dej, tus nqi hydrolysis sai, muaj peev xwm nqus tau zoo, tsim cov plhaub loj, kev sib sau ua ke sai, qhov tsis muaj dej ntau, thiab kev ua haujlwm zoo ntawm kev qhuav dej. Cov khoom txau kom qhuav tuaj yeem ua kom muaj kev nyab xeeb, txo cov xwm txheej dej, thiab muab dej haus zoo thiab txhim khu kev qha rau cov neeg nyob hauv. Yog li ntawd, Poly Aluminium Chloride/PAC kuj tseem hu ua polyaluminum chloride ua haujlwm siab, PAC ua haujlwm siab lossis polyaluminum chloride ua haujlwm siab. Poly Aluminium Chloride/PAC yog qhov tsim nyog rau cov dej nyoos ntawm ntau yam turbidity, thiab muaj ntau yam pH daim ntawv thov, tab sis piv nrog polyacrylamide, nws cov nyhuv sedimentation qis dua polyacrylamide.
