PAC Flocculant
Selelekela
Polyaluminium chloride ke flocculant e sebetsang ka bongata e sebelisoang haholo kalafong ea metsi, kalafo ea likhoerekhoere, tlhahiso ea makhasi le indasteri ea masela. Ts'ebetso ea eona e nepahetseng ea flocculation le ts'ebeliso e bonolo e etsa hore e be moemeli oa bohlokoa oa ho thusa lits'ebetsong tse fapaneng tsa indasteri.
Polyaluminium chloride (PAC) ke motsoako oa aluminium chloride le hydrates. E na le ts'ebetso e ntle ea flocculation le tšebeliso e pharaletseng 'me e ka sebelisoa ho hloekisa metsi, ho hloekisa likhoerekhoere, tlhahiso ea pulp, indasteri ea masela le masimo a mang. Ka ho etsa floc, PAC e tlosa ka katleho likaroloana tse emisitsoeng, li-colloid le lintho tse qhibilihisitsoeng ka metsing, ho ntlafatsa boleng ba metsi le liphello tsa phekolo.

Lisebelisoa
Phekolo ea metsi:PAC e sebelisoa haholo phepelong ea metsi litoropong, metsi a indasteri le lits'ebetsong tse ling tsa tlhoekiso ea metsi. E khona ho phaphamala, ho theola le ho tlosa litšila metsing ho ntlafatsa boleng ba metsi.
Phekolo ea likhoerekhoere:Litsing tsa ho hloekisa likhoerekhoere, PAC e ka sebelisoa ho thella seretse, ho tlosa lintho tse tiileng ka har'a metsi a litšila, ho fokotsa matšoao a kang COD le BOD, le ho ntlafatsa katleho ea tsamaiso ea likhoerekhoere.
Tlhahiso ea pulp:Joalo ka flocculant, PAC e ka tlosa litšila ka har'a makhasi, ea ntlafatsa boleng ba makhasi le ho khothaletsa tlhahiso ea pampiri.
Indasteri ea masela:Ts'ebetsong ea ho daea le ho qeta, PAC e ka sebelisoa e le flocculant ho thusa ho tlosa likaroloana tse emisitsoeng le ho ntlafatsa bohloeki ba ho daea le ho qeta mokelikeli.
Lisebelisoa tse ling tsa indasteri:PAC e ka boela ea sebelisoa merafong leaching, ente ea metsi tšimong ea oli, tlhahiso ea manyolo le masimo a mang, 'me e na le mefuta e mengata ea liindasteri.
Ho paka Sehlahisoa le Lipalangoang
Foromo ea ho paka: PAC hangata e fanoa ka mokhoa oa phofo e tiileng kapa mokelikeli. Hangata phofo e tiileng e kenngoa ka mekotleng e lohiloeng kapa mekotleng ea polasetiki, 'me lino tse metsi li tsamaisoa ka libarele tsa polasetiki kapa literaka tsa litanka.
Litlhoko tsa lipalangoang: Nakong ea lipalangoang, mocheso o phahameng, letsatsi le tobileng le tikoloho e mongobo li lokela ho qojoa. Mokelikeli PAC o lokela ho sireletsoa hore o se ke oa lutla le ho tsoakana le lik'hemik'hale tse ling.
Maemo a polokelo: PAC e lokela ho bolokoa sebakeng se phodileng, se omileng, hole le mehloli ea mollo le lintho tse tukang, le hole le mocheso o phahameng.
Tlhokomeliso: Ha u tšoara le ho sebelisa PAC, lisebelisoa tse loketseng tsa tšireletso li lokela ho apesoa ho qoba ho kopana ka kotloloho le letlalo le mahlo. Haeba u kopane ka phoso, hlatsoa hang-hang ka metsi a hloekileng.
