PAC e etsa eng tabeng ea ho hloekisa metsi?

Polyaluminium chloride (PAC) e bapala karolo ea bohlokoa lits'ebetsong tsa kalafo ea metsi, e sebetsa joalo ka coagulant le flocculant e sebetsang. Tabeng ea tlhoekiso ea metsi, PAC e sebelisoa haholo ka lebaka la ho sebetsa ka mokhoa o fapaneng le ho sebetsa hantle ha ho tlosa litšila mehloling ea metsi. Motsoako ona oa lik'hemik'hale ke karolo ea bohlokoa methating ea coagulation le flocculation, e thusa ho ntlafatsa ts'ebetso e akaretsang ea limela tsa ho hloekisa metsi.

Coagulation ke mohato oa pele oa ho hloekisa metsi, moo PAC e kenyelletsoang metsing a tala. Li-ion tsa aluminium tse qosoang hantle tse ho PAC li fokotsa litefiso tse mpe tsa likaroloana tse emisitsoeng ka metsing, li etsa hore li kopane. Likaroloana tsena tse kopantsoeng li etsa lihlopha tse kholoanyane le tse boima ho feta, ho etsa hore ho be bonolo hore li tsoe ka metsing nakong ea mekhoa e latelang. Mokhoa oa ho kopanya o bohlokoa bakeng sa ho tlosa litšila tsa colloidal le tse emisitsoeng tse ka 'nang tsa se ke tsa hloekisoa habonolo.

Flocculation e latela coagulation mme e kenyelletsa ho sisinyeha ha bonolo kapa ho tsoaka ha metsi ho khothaletsa ho thehoa ha lihlopha tse kholoanyane ho tloha likarolong tse kopantsoeng. PAC e thusa mothating ona ka ho fana ka litefiso tse ling tse ntle, ho khothaletsa ho thula le ho kopanya likaroloana ho theha lihlopha tse kholoanyane le tse teteaneng. Li-flocs tsena li lula ka katleho nakong ea sedimentation, e leng se tlatsetsang ho metsi a hloekileng.

O mong oa melemo e hlokomelehang ea PAC phekong ea metsi ke ho ikamahanya le maemo a fapaneng a boleng ba metsi. E sebetsa hantle libakeng tse nang le asiti le alkaline, e etsa hore e tšoanelehe ho phekola mehloli e fapaneng ea metsi. Ntle le moo, PAC e sebetsa hantle ho sebetsana le boemo bo feto-fetohang ba metsi mme e ka sebelisoa lits'ebetsong tse fapaneng tsa kalafo ea metsi, ho kenyeletsoa kalafo ea metsi a nooang, kalafo ea metsi a indasteri le tlhoekiso ea metsi a litšila.

PAC e bapala karolo ea bohlokoa lits'ebetsong tsa ho hloekisa metsi, ho thusa ho kopanya le ho phalla ho tlosa litšila mehloling ea metsi. Ho ikamahanya le maemo, ho baballa litšenyehelo, le melemo ea tikoloho li e etsa sesebelisoa sa bohlokoa ha ho batloa phepelo ea metsi a hloekileng le a sireletsehileng. Ho utloisisa bohlokoa ba PAC tlhoekisong ea metsi ho totobatsa bohlokoa ba eona ho rarolla mathata a boleng ba metsi lefatšeng ka bophara.
