PAM bakeng sa phekolo ea Metsi
Selelekela
PAM (Polyacrylamide) ke mofuta oa polymer o sebelisoang lits'ebetsong tse fapaneng, ho kenyelletsa le ho hloekisa metsi.Polyacrylamide e atisa ho sebelisoa e le flocculant ka mekhoa ea phekolo ea metsi ho ntlafatsa ho lokisoa ha likaroloana tse emisitsoeng, ho etsa hore ho be bonolo ho arola lintho tse tiileng le metsi.
Polyacrylamide (PAM) ke motsoako oa polymer o sebelisoang haholo tšimong ea ho hloekisa metsi.E tla ka mefuta e mengata e fapaneng, ho kenyelletsa nonionic, cationic, le anionic.

Lisebelisoa
Floculant:Polyacrylamide e atisa ho sebelisoa e le flocculant ka kalafo ea metsi ho tlosa solids emisitswe, particulate taba le colloids le condense bona ka flocs khōloanyane ho bebofatsa sedimentation latelang kapa filtration.Flocculation ena e thusa ho ntlafatsa ho hlaka le ho hlaka ha metsi.
Sehlahisoa sa Precipitant:Polyacrylamide e ka etsa li-complexes tse nang le li-ion tsa tšepe ho ntlafatsa phello ea precipitant.Ha o phekola metsi a litšila a nang le li-ion tsa tšepe, tšebeliso ea polyacrylamide e ka ntlafatsa phello ea pula le ho fokotsa litaba tsa li-ion tsa tšepe metsing a litšila.
Antiscaant:Ts'ebetsong ea phekolo ea metsi, polyacrylamide e ka boela ea sebelisoa e le sekala sa inhibitor ho thibela ho fokotseha ka holim'a liphaephe le lisebelisoa.E ntlafatsa ho leka-lekana ha ion ea metsi, e thibela ho kenngoa ha lintho tse qhibilihisitsoeng metsing, 'me e fokotsa ho thehoa ha sekala.
Ntlafatso ea boleng ba metsi:Polyacrylamide e ka boela ea sebelisoa ho ntlafatsa boleng ba metsi maemong a mang, joalo ka ho eketsa sekhahla sa sedimentation sa lintho tse tiileng tse emisitsoeng ka metsing, ho fokotsa sebopeho sa seretse, joalo-joalo.
Ho tiisa mobu:Ho tiisa mobu le ho ntlafatsa, polyacrylamide e ka sebelisoa ho ntlafatsa botsitso le ho hanyetsa ha mobu oa mobu, ka tsela eo ho ntlafatsa thepa ea 'mele ea mobu.
Hoa lokela ho hlokomeloa hore tekanyo ea polyacrylamide e lokela ho laoloa ka hloko nakong ea tšebeliso ho qoba liphello tse mpe tikolohong.Ho phaella moo, kopo e khethehileng e itšetlehile ka litlhoko tse khethehileng tsa phekolo ea metsi le litšobotsi tsa boleng ba metsi.
