Tabeng ea ho hloekisa metsi, ho batla metsi a hloekileng le a sireletsehileng a nooang ke ntho e ka sehloohong. Har'a lisebelisoa tse ngata tse fumanehang bakeng sa mosebetsi ona,polyacrylamide(PAM), e tsejoang hape e le coagulant, e hlahella e le ntho e sebetsang ka mokhoa o fapaneng le e sebetsang. Tšebeliso ea eona ts'ebetsong ea phekolo e tiisa ho tlosoa ha litšila le litšila, ka hona ho matlafatsa boleng ba metsi a nooang. Sengoliloeng sena se kenella lits'ebetsong tse fapaneng tsa polyacrylamide kalafong ea metsi a nooang, se hlakisa karolo ea eona e le karolo ea bohlokoa ts'ebetsong ea tlhoekiso.
1. Coagulationle Flocculation
E 'ngoe ea likopo tsa mantlha tsa polyacrylamide kalafong ea metsi a nooang ke ts'ebetsong ea ho kopanya le ho phalla. Coagulation e kenyelletsa ho senyeha ha likaroloana tsa colloidal ka ho eketsoa ha lik'hemik'hale, ho thusa ho bokellana ha tsona. polyacrylamide e thusa ts'ebetsong ena ka ho fokotsa tefiso e mpe holim'a likaroloana tse emisitsoeng, ho khothalletsa ho bokellana ha tsona hore e be lihlopha tse kholoanyane, tse tsitsitseng. Ka mor'a moo, flocculation e tiisa ho thehoa ha lihlopha tse kholoanyane le tse teteaneng, tse ka tlosoang habonolo ka mekhoa ea sedimentation kapa filtration.
2. Phallo e Matlafatsoang ea Litšilafalo
polyacrylamide e ntlafatsa ts'ebetso ea ho tlosa litšila tse fapaneng tse teng metsing a nooang. Ka ho nolofatsa ho thehoa ha li-flocs tse khōloanyane, e ntlafatsa mekhoa ea sedimentation le filtration, e lebisang ho tlosoeng hantle ha lintho tse tiileng tse emisitsoeng, lintho tse phelang le likokoana-hloko. Ho phaella moo, PAM e thusa ho tlosoa ha litšepe tse boima, tse kang lead le arsenic, ka ho etsa li-complexes tse nang le li-ion tsena, kahoo li thibela ho hasana ha tsona ka metsing a hloekisitsoeng.
3. Phokotso ea Moferefere
Moferefere, o bakoang ke likaroloana tse emisitsoeng ka metsing, ha o ame feela boleng bo botle ba metsi a nooang empa hape o sebetsa e le sesupo se ka bang teng sa boleng ba metsi. polyacrylamide ka katleho ho fokotsa turbidity ka ho kgothaletsa aggregation ea likaroloana tse ntle ka flocs khōloanyane, e leng rarolla ka potlako ho feta. Sena se fella ka metsi a nooang a hlakileng le a khahlisang pono, a kopanang le litekanyetso tsa taolo le litebello tsa bareki.
Qetellong, Polyacrylamide (PAM) e bapala karolo ea bohlokoa kalafong ea metsi a nooang, e fana ka melemo e mengata ho latelaCoagulation, ho tlosa litšila, ho fokotsa moferefere, ho tlosoa ha algae, le phetoho ea pH. Sebopeho sa eona se feto-fetohang le bokhoni ba sona bo etsa hore e be sesebelisoa sa bohlokoa bakeng sa lifeme tse hloekisang metsi tse lekang ho fana ka metsi a nooang a hloekileng, a sireletsehileng le a khahlisang ho bareki. Ha tsoelo-pele ea theknoloji ea kalafo ea metsi e ntse e tsoela pele ho fetoha, Polyacrylamide e mothating oa ho lula e le lejoe la motheo la ho batla taolo e tsitsitseng ea metsi le ts'ireletso ea bophelo bo botle ba sechaba.
