Polyaluminium Chride (Pac) ke motsoako oa aluminium clodides le li-hydraides. E na le ts'ebetso ea lipalesa le ho etsa lintho tse ngata 'me e ka sebelisoa kalafo ea metsi, kalafo ea likhomo, tlhahiso ea makhasi, indasteri e meng le masimo a masela le masimo a makgesi. Ka ho theha lipalesa, pac e tlosa likaroloana tse emisitsoeng, li-colloids le lintho tse senotsoeng metsing, li ntlafatsa litlamorao tsa metsi le kalafo.

TLHOKOMELISO:Pac e sebelisoa haholo phepelo ea metsi a litoropong, metsi a indasteri le lits'ebetso tse ling tsa kalafo tsa metsi. E ka mela ka katleho, e tlosa bohlola metsing ho ntlafatsa boleng ba metsi.
Phekolo ea Sewage:Litšila tsa kalafo tsa Sewage, pac li ka sebelisoa ho mela e emisitsoeng, tlosa lisosa tse senyehileng, fokotsa matšoao a kang lefu la likhoka.
Tlhahiso ea pulp:Joaloka lipalesa, pac e ka tlosa litšila tse pulp, ntlafatsa boleng ba makhasi, 'me ho khothaletsa tlhahiso ea pampiri.
Indasteri ea masela:Ts'ebetsong ea ho daela le ho qeta, Pac e ka sebelisoa e le lipalesa ho thusa ho tlosa likaroloana tse emisitsoeng le ho ntlafatsa bohloeki ba dae le ho qeta metsi.
Likopo tse ling tsa indasteri:Pac e ka sebelisoa le ho thetsoa ka meching ea metsing, entetsi ea metsi a oli, tlhahiso ea manyolo le likarolo tse ling, 'me li na le lits'ebetso tse ngata tsa indasteri.
Ho paka ha sehlahisoa le lipalangoang
Foromo ea ho paka: Pac hangata e fanoa ka mokhoa oa phofo kapa metsi a tiileng. Polao e tiileng hangata e tletse ka mekotleng e lohiloeng kapa mekotleng ea polasetiki, 'me lino tse tsamaisoang ka lijana tsa polasetiki kapa literaka tsa tanka.
Litlhoko tsa lipalangoang: Nakong ea lipalangoang, mocheso o phahameng, ho boloka letsatsi le mofuthu la khanya ea letsatsi le ho mongobo ho lokela ho qojoa. Liquid PAC li lokela ho sireletsoa ho tloha li tsoa ho tsoa le ho kopanya le lik'hemik'hale tse ling.
Maemo a polokelo: pac e lokela ho bolokoa sebakeng se pholileng, se omileng, hole le mehloli ea mollo le lintho tse tukang, le hole le mocheso o phahameng.
Tlhokomeliso: Ha u sebetsana le ho sebelisa pac, lisebelisoa tse loketseng tsa ts'ireletso li lokela ho apesoa ho qoba ho buisana le letlalo le mahlo. Haeba u kopa ka tšohanyetso, e hlakisang hang-hang ka metsi a hloekileng.
