Phekolo ea metsi ke karolo ea bohlokoa ea ts'ireletso ea tikoloho le bophelo ba sechaba, 'me morero oa eona ke ho netefatsa boleng ba metsi le ho tobana le litlhoko tsa likopo tse fapaneng. Har'a mekhoa ea kalafo ea metsi,Polyluminium Chhellium(Pac) e khethiloe haholo bakeng sa thepa ea eona e ikhethang le phello e sebetsang hantle.
Phello e sebetsang hantle: PAC e na le ts'ebetso e ntle haholo ebile e ka tlosa litšila tse kang li-solisid, li-colloids le tsa ho ntlafatsa boleng ba metsi.
Mechanism ea Coagulation ea Pac
Mochine oa polyaluminium chloniminium chlolide (Pac) joalo ka koluoa e kenyelletsa compress ea mokelikeli o habeli, o qosa ho se nke lehlakore le ho ts'oara le ho ts'oasa le ho ts'oaroa ha parate le ho hlohlona. TLHOKOMELISO EA FLAND ea motlakase e habeli e bolela hore kamora ho eketsa pec ho metsi, alurium litsi tsa motlakase, ka hona li hahlaula mola oa motlakase, ka hona o hatella metsi a mabeli ka holim'a likaroloana tsa colloridal, ka hona a ba etsa hore ba senyehe le majoe; Li-coriling tsa Adsorpption cutions ke limolek'hule tse mpe tse khahlang e mong le e mong holim'a likaroloana tsa "borokho" tsa "borokho" Tšusumetso e nang le marang-rang e ka mokhoa oa ho adisa le ho koetlisa li-molecales tsa pac le likaroloana tsa colloridal, tse nang le likarolo tsa colloridal. E ts'oaroa marang-rang a limolek'hule tsa kou.
Phatlalatso ea Phyaluminium chlorade ea metsi
Ha ho bapisoa le li-flocculants tse sa sebetseng hantle, e ntlafalitse haholo phello ea li-daes. Mokhoa oa eona oa ts'ebetso ke hore Pac e ka khothaletsa limolek'hule tsa dae ho etsa li-floc tse ntle ka har'a compression kapa ho se nke lehlakore ha sekala se habeli sa motlakase.
Ha PAM e sebelisoa hammoho le Pac, limolek'hule tsa limoleke tsa li-anionic li ka sebelisa cookisic manyolo ka likhoele tsa bona tse telele ho hlahisa li-flocs tse telele ka tšebelisano ea motho ea sotlehang. Ts'ebetso ena e thusa ho ntlafatsa ts'ebetso ea ho rarolla le ho ba bonolo ho e tlosa. Ntle le moo, palo e kholo ea lihlopha tsa moamoheli ea limolek'hule tsa lipelaelo tsa Ananic Polycerlamide li ka theha limolek'hule tsa ionic le-welecules deye limolek'hule. Sebopeho sa bonngoe ona ba lik'hemik'hale se fokotsa sello sa manyolo ka metsing, ka ho etsa joalo o khothaletsa sebopeho se potlakileng le pula ea lipalesa. Mechine ena e tlamang e boima e etsa hore e be thata haholo bakeng sa li-Ion tse boima tsa tšepe ho phonyoha, li ntlafatsa katleho le katleho ea kalafo.
Mabapi le ho tlosa phosphorus, katleho ea polyaluminium chloride e ke ke ea hlokomolohuoa. Ha e eketsoa ho phosphorus - e nang le metsi a litšila, e ka hydrolyze ho hlahisa li-Ion tsa tšepe tse tlisoang ke metal. Li-ion li tla qhibiliha ho qhibiliha flates flates ka metsi a litšila, ho fetola morao hore e be phosphabuble ea fropute. Ts'ebetso ena ea phetoho e tlosang ka nepo e tlosa li-Ions tsa phosphate tsa metsi le ho fokotsa tšusumetso e mpe ea phosphorus ea mebele ea metsi.
Ntle le karabelo e tobileng le phosphate, phello ea cuyaluminium Chride hape e phetha karolo ea bohlokoa ts'ebetsong ea ho tlosa phosphorus. E ka fihlela Adsorption le borikhoe ka ho hatella li-ISSphate Isphate Ions. Ts'ebetso ena e baka phosphate le tšibollo ea batho ba bang ba manybeng ho ea matha kapele ho li-clups, ho theha lipalesa tse bonolo ho li rarolla.
Habohlokoa le ho feta, hobane lisebelisoa tse ntle tse entsoeng ka mor'a hore li nke mochini o ikhethang oa ho hula phooshoang, 'me o be matla, ebe o nyahlatsa,' me a phatlalla likaroloana tse kholo. Likarolo tsena li lula mokatong o ka tlase, 'me ka karohano e tiileng ea metsi, metsi a phahameng a metsi a ka lokolloa, ka ho etsa joalo o khona ho tlosa lephoka. Libetsa tse rarahaneng tsa 'mele le tsa lik'hemik'hale li tiisa ts'ebetso ea metsi a senyang metsi, e fana ka tiiso e tiileng ea ts'ireletso ea tikoloho le ts'ebetso ea metsi.
