Ho na le phapang e kholo lipakeng tsa grade grade polyaluminium chloride (PAC) le polyaluminium chloride ea metsi a nooang ka har'a matšoao a 'maloa a bohlokoa le maemo a ts'ebeliso, ka tsela e latelang:

Indastering e atlehileng ea kalafo ea metsi, tlhoko ea polyaluminium chloride e le k'hemik'hale ea bohlokoa ea kalafo ea metsi e ntse e hola butle. Bakeng sa lik'hamphani tse hlokang ho reka polyaluminium chloride e ngata, ho bohlokoa ho khetha morekisi ea tšepahalang. Henan Aierfuke Chemicals Co.,Ltd. e hlahella har'a bareki ba bangata ka lebaka la melemo ea eona ea bohlokoa ka theko, boleng, le tšebeletso ea ka mor'a thekiso.

Polyized ferrosulfate (PFS) e bontšitse tebello e pharaletseng ea ts'ebeliso mafapheng a mangata ka ts'ebetso ea eona e phahameng, ts'ireletso ea tikoloho le litšobotsi tse ngata tse sebetsang. Ho kopantsoe le mokhoa oa hajoale oa nts'etsopele ea mahlale a morao-rao le tlhoko ea 'maraka, tataiso ea nts'etsopele ea nako e tlang e bonts'oa haholo likarolong tse latelang:

Polyaluminium chloride (PAC) ke motsoako oa polymer oa inorganic, mme ho tlosoa ha fluoride ho bonoa haholo ka mekhoa e 'meli e latelang:

Chemisorption: PAC e qhibilihisoa ka metsing e lokolle aluminium ion (Al³), 'me e kopantsoe le fluoride ion (F) ho etsa hydrofluoric acid (HF) mahareng, ebe e tsoela pele ho theha pula ea insoluble aluminium fluoride (AlF ₃).

Co-precipitation effect: aluminium hydroxide colloid e hlahisoang ke PAC hydrolysis e apesa ion ea fluorine ea mahala ka ho adsorption le ho ts'oara mesh, 'me qetellong e e tlose ka karohano ea metsi a tiileng.

Polyaluminium chloride (PAC, e le sesebelisoa se phahameng sa ho hloekisa metsi) e sebelisoa haholo ho hloekisa metsi a nooang, ho hloekisa metsi a litšila a indasteri le masimo a mang. Leha ho le joalo, joalo ka sehlahisoa sa lik'hemik'hale, ea senya 'me e ka baka likotsi tsa bophelo bo botle. Pampiri ena e kopanya litloaelo tsa indasteri le mehato ea ts'ohanyetso, e akaretsa ka mokhoa o hlophisehileng lintlha tsa ts'ebetso ea ts'ireletso bakeng sa litšupiso tsa litsebi.

Polyaluminium Chloride (PAC), e nang le foromo ea lik'hemik'hale Al2(OH)nCl6−nAl2 (OH)n.Cl6−nₘ, ke "polymer coagulant" e sebetsang hantle haholo. E hlahisoa ka hydrolysis le polymerization ea letsoai la aluminium, PAC e na le bokhoni bo matla ba ho bapatsa, ho phalla ka potlako, le ho ikamahanya le maemo ho pholletsa le mefuta e mengata ea pH. E sebelisoa haholo ka har'atlhoekiso ea metsi a nooang, ho hloekisa metsi a litšila a indasteri, tsamaiso ea likhoerekhoere tsa litoropo, le tse ling.
