Poly Aluminium Chloride ke eng?
Poly Aluminium Chloride, eo hangata e khutsufatsoang e le PAC, ke k'hemik'hale e kopanyang lik'hemik'hale e sebelisoang hangata lits'ebetsong tsa ho hloekisa metsi.E tsoa ho aluminium chloride ka ho itšoara ka hydroxide, sulfate, kapa letsoai le leng.PAC e tumme ka bokhoni ba eona ba ho tlosa lintho tse tiileng tse fanyehiloeng, lintho tse phelang le litšila tse ling metsing, e leng se etsang hore e be khetho e nepahetseng bakeng sa lits'ebetso tse fapaneng tsa tlhoekiso.
PAC e sebetsa joang?
PAC e sebetsa joalo ka coagulant le flocculant kalafo ea metsi.Ha e kenngoa ka metsing, e etsa liketane tsa polymer tse qosoang hantle tse fokotsang likaroloana tse nang le litšila tse kang litšila, litšila le likokoana-hloko.Likaroloana tsena tse se nang lehlakore li bokana hammoho ho ba likaroloana tse khōloanyane tse bitsoang flocs.Likokoana-hloko tsena li lula fatše, e leng ho lumellang metsi a hlakileng hore a arohane le sediment.Ts'ebetso ena e sebetsa haholo ho tloseng mefuta e mengata ea lintho tse silafatsang, ho kenyeletsoa litšepe tse boima, libaktheria le metsoako ea lintho tse phelang.

Katleho: PAC e fana ka coagulation e potlakileng le flocculation, e bakang tlhoekiso e potlakileng ha e bapisoa le mekhoa ea setso.
Mefuta-futa: E ka sebelisoa mehloling e fapaneng ea metsi, ho kenyelletsa tlhoekiso ea metsi a nooang, tlhoekiso ea metsi a litšila, lits'ebetso tsa indasteri le tse ling.
Tlhahiso e Fokotseng ea Sludge: PAC e hlahisa litšila tse nyane ha e bapisoa le li-coagulants tse ling, e fokotsa litšenyehelo tsa ho lahla le tšusumetso ea tikoloho.
Mamello ea pH: E sebetsa ka katleho ho pholletsa le mefuta e mengata ea pH, e fana ka liphello tse tsitsitseng maemong a fapaneng a metsi.
Katleho ea Litšenyehelo: Ho sebetsa hantle ha PAC, ho kopantsoe le litlhoko tsa eona tse tlase tsa litekanyetso, ho ka lebisa ho bolokoeng ha litšenyehelo lits'ebetsong tsa kalafo.
