Polyacrylamide(PAM) ke hydrophilic synthetic polymer e sebelisoang haholo lits'ebetsong tsa kalafo ea metsi. Haholo-holo e sebelisoa e le flocculant le coagulant, lik'hemik'hale tse etsang hore likaroloana tse emisitsoeng ka metsing li kopane ka lihlopha tse kholoanyane, kahoo li thusa ho tlosoa ha tsona ka ho hlakisoa kapa ho sefa. Ho itšetlehile ka boleng ba metsi a litšila, sebelisa cationic, anionic, kapa PAM e seng ea ionic. Polyacrylamide e fana ka melemo e mengata kalafong ea metsi, ho kenyeletsoa katleho ea eona holim'a mefuta e mengata e fapaneng ea pH, mocheso le maemo a turbidity. Phello ea coagulation e ka lekoa ho sebelisoa liteko tsa Jar kapa tekanyo ea turbidity.
Polyacrylamide ka ho pharaletseng sebelisoa ka liindasteri metsi kalafo, likhoerekhoere kalafo, litšila metsi, joalo-joalo Ka dimela kalafo metsi, Polyacrylamide e sebelisoa ka dithulaganyo tse sa tšoaneng, ho akarelletsa le tlhaloso ka sehloohong le ea bobeli, filtration, le disinfection. Nakong ea ts'ebetso ea mantlha ea ho hlakisa, e eketsoa metsing a tala ho khothaletsa ho lokisoa ha lintho tse tiileng tse emisitsoeng, ebe li tlosoa ka sedimentation kapa flotation. Tlhalosong ea bobeli, polyacrylamide e sebelisetsoa ho hlakisa metsi a hloekisitsoeng ka ho tlosa lintho tse setseng tse emisitsoeng le lintho tse phelang tse adsorbed.
Molao-motheo oa ts'ebetso eapolyacrylamide flocculantke: ka mor'a ho eketsa tharollo ea PAM, PAM e adsorbs holim'a likaroloana, ho etsa marokho pakeng tsa bona. Ka letamong la pele, e khomarela ho theha lihlopha tse kholoanyane, 'me' mele oa metsi o fetoha moferefere ka nako ena. Ka mor'a hore palo e kholo ea lihlopha e hōle 'me e be e teteaneng, e tla falla ebe e teba butle-butle ha nako e ntse e ea,' me karolo e ka holimo ea metsi a tala e tla hlaka. Ts'ebetso ena ea aggregation e ntlafatsa litšobotsi tsa ho rarolla likaroloana, ho etsa hore ho be bonolo ho li tlosa nakong ea ho hlakisoa kapa ho sefa. Polyacrylamide e atisa ho sebelisoa hammoho le li-coagulants tse ling le li-flocculants ho finyella tlhaloso e nepahetseng le ts'ebetso ea ho hloekisa.
Polyacrylamide e boetse e phetha karolo ea bohlokoa ho tlhoekisoeng ha metsi. Hangata e sebelisoa e le sefa pele ho li-filters kapa mekhoa e meng ea ho hloekisa 'meleng ho tlosa lintho tse tiileng tse emisitsoeng le turbidity. Ka ho ntlafatsa ho tlosoa ha likaroloana tsena, polyacrylamide e thusa ho netefatsa hore ho na le filtrate e hlakileng, e hloekileng.
Polyacrylamide ke polymer e batlang e tsitsitse ebile e se chefo e senyehang ka mekhoa ea tlhaho kapa mekhoa ea kalafo ea likokoana-hloko. Hoa lokela ho hlokomeloa hore tharollo e tšolotsoeng e tla etsa hore fatše e be e thellang haholo, e leng se ka lebisang ho oela.
Leha ho le joalo, palo ea PAM e sebelisitsoeng e itšetlehile ka mofuta oa metsi a litšila le likahare tsa likaroloana tse tiileng tse emisitsoeng, hammoho le boteng ba lik'hemik'hale tse ling, li-acids le litšila metsing. Lintlha tsena li ka ama phello ea coagulation ea PAM, kahoo liphetoho tse utloahalang li lokela ho etsoa nakong ea tšebeliso. Lihlahisoa tsa PAM tse nang le litekanyo tse fapaneng tsa limolek'hule, li-degree tsa ionic, le litekanyetso li lokela ho khethoa ka hloko bakeng sa mefuta e fapaneng ea metsi a litšila.
