Yintoni eyenziwa yi-PAC kunyango lwamanzi?

I-Polyaluminum chloride (I-PAC) idlala indima ebalulekileyo kwiinkqubo zokunyanga amanzi, isebenza njenge-coagulant esebenzayo kunye ne-flocculant. Kwicandelo lokucocwa kwamanzi, i-PAC isetyenziswa kakhulu ngenxa yokuguquguquka kwayo kunye nokusebenza kakuhle ekususeni ukungcola kwimithombo yamanzi. Le khemikhali idlala indima ephambili kwizigaba zokuxinana kunye ne-flocculation, inceda ukuphucula ukusebenza kakuhle kwezityalo zokunyanga amanzi.

Ukujiya kwamanzi linyathelo lokuqala ekunyangweni kwamanzi, apho i-PAC yongezwa kumanzi aluhlaza. Ii-ion ze-aluminium ezitshajiweyo kakuhle kwi-PAC zithomalalisa ii-negative charges kumasuntswana axhonyiweyo emanzini, nto leyo ebangela ukuba zihlangane. La masuntswana ajiyileyo enza ii-aggregates ezinkulu nezinzima, nto leyo eyenza kube lula ukuba ziphume emanzini ngexesha leenkqubo ezilandelayo. Inkqubo yokujiya kwamanzi ibalulekile ekususeni ukungcola kwe-colloidal kunye nokujiyileyo okungenakuhluzwa lula.

Ukuqunjelwa emva kokujiya kwaye kubandakanya ukuxutywa okanye ukuxutywa kwamanzi kancinci ukukhuthaza ukwakheka kwee-flocs ezinkulu ezivela kwii-particles ezijiyileyo. I-PAC inceda kweli nqanaba ngokubonelela ngee-charges ezongezelelweyo ezilungileyo, ikhuthaza ukungqubana kunye nokuhlanganiswa kwee-particles ukuze zenze ii-flocs ezinkulu nezixineneyo. Ezi flocs zihlala kakuhle ngexesha lokuqunjelwa, zinegalelo kumanzi acacileyo.

Enye yeenzuzo eziphawulekayo ze-PAC ekunyangweni kwamanzi kukuba iyakwazi ukuziqhelanisa neemeko ezahlukeneyo zomgangatho wamanzi. Isebenza kakuhle kwiindawo ezine-asidi kunye ne-alkaline, nto leyo eyenza ukuba ifaneleke ukunyanga imithombo yamanzi eyahlukeneyo. Ukongeza, i-PAC iyasebenza ekuphatheni ukungcoliswa kwamanzi okutshintshatshintsha kwaye ingasetyenziswa kwiindawo ezahlukeneyo zokunyanga amanzi, kubandakanya ukunyanga amanzi okusela, ukunyanga amanzi emizi-mveliso, kunye nokunyanga amanzi amdaka.

I-PAC idlala indima ebalulekileyo kwiinkqubo zonyango lwamanzi, inceda ekujiyeni nasekufudumaleni kwamanzi ukuze kususwe ubumdaka kwimithombo yamanzi. Ukuziqhelanisa kwayo, ukusebenza kakuhle kweendleko, kunye neenzuzo zokusingqongileyo kuyenza ibe sisixhobo esibalulekileyo ekufuneni amanzi acocekileyo nakhuselekileyo. Ukuqonda ukubaluleka kwe-PAC ekunyangweni kwamanzi kugxininisa ukubaluleka kwayo ekusombululeni imingeni yomgangatho wamanzi kwihlabathi liphela.
