Polyaluminium chloride muaj cov txiaj ntsig zoo tshaj plaws hauv kev lag luam, yog dav yoog raws dej, yooj yim thiab sai tsim cov flakes loj, muaj nag lossis daus ua haujlwm zoo, thiab muaj ntau yam tsim nyog pH nqi (5-9).
Kev lag luam Polyaluminium chloride yog ib qho inorganic polymer flocculant, uas tuaj yeem siv rau hauv kev kho dej thiab kev kho dej hauv kev lag luam, rov ua dua cov thee mine scouring cov dej khib nyiab thiab cov plooj (porcelain industrial wastewater), thiab tseem tuaj yeem siv hauv luam ntawv. Factories, luam ntawv thiab dyeing nroj tsuag, tanneries, breweries, nqaij ua cov nroj tsuag, tshuaj nroj tsuag, ntawv mills, thee ntxuav, metallurgy, mining cheeb tsam, thiab kev kho cov dej khib nyiab uas muaj fluorine, roj, thiab hnyav hlau.
