I-PAC yenzani ekuhlanzeni amanzi?

I-Polyaluminium chloride (I-PAC) idlala indima ebalulekile ezinqubweni zokwelashwa kwamanzi, isebenza njenge-coagulant ephumelelayo ne-flocculant. Emkhakheni wokuhlanza amanzi, i-PAC isetshenziswa kakhulu ngenxa yokuguquguquka kwayo nokusebenza kahle ekususeni ukungcola emithonjeni yamanzi. Le nhlanganisela yamakhemikhali ibamba iqhaza elibalulekile ezigabeni zokuhlangana kanye ne-flocculation, okusiza ukuthuthukisa ukusebenza kahle okuphelele kwezitshalo zokuhlanza amanzi.

I-coagulation yisinyathelo sokuqala ekuhlanzeni amanzi, lapho i-PAC yengezwa emanzini aluhlaza. Ama-ion aluminium afakwe kahle ku-PAC anciphisa izindleko ezingezinhle ezinhlayiyeni ezimisiwe emanzini, azenze zihlangane. Lezi zinhlayiya ezijiyile zakha amaqoqo amakhulu futhi asindayo, okwenza kube lula ukuthi ziphume emanzini ngesikhathi sezinqubo ezilandelayo. Inqubo ye-coagulation ibalulekile ekususeni ukungcola kwe-colloidal nokumisiwe okungenzeka kungahlungiki kalula.

I-Flocculation ilandela ukuhlangana futhi ihilela ukunyakaziswa okumnene noma ukuxutshwa kwamanzi ukuze kukhuthaze ukwakheka kwezinhlayiya ezinkulu ezivela ezinhlayiyeni ezihlangene. I-PAC isiza kulesi sigaba ngokuhlinzeka ngamashaji angeziwe, ukukhuthaza ukungqubuzana nokuhlanganiswa kwezinhlayiya ukuze kwakheke ama-flocs amakhulu nakakhulu futhi aminyene. Lezi zinhlanzi zihlala ngokuphumelelayo ngesikhathi sokuthuthwa kwe-sedimentation, okunomthelela emanzini ahlanzekile.

Enye yezinzuzo eziphawulekayo ze-PAC ekuhlanzeni amanzi ukuguquguquka kwayo ezinhlobonhlobo zezimo zekhwalithi yamanzi. Isebenza kahle kuzo zombili izindawo ezine-acidic kanye ne-alkaline, iyenze ifaneleke ukwelapha imithombo yamanzi eyahlukene. Ukwengeza, i-PAC iyasebenza ekuphatheni ukuguquguquka kwamanzi okuguquguqukayo futhi ingasetshenziswa ezinhlelweni ezihlukahlukene zokuhlanza amanzi, okuhlanganisa ukuhlanzwa kwamanzi okuphuza, ukuhlanzwa kwamanzi ezimbonini, nokuhlanza amanzi angcolile.

I-PAC idlala indima ebaluleke kakhulu ezinqubweni zokuhlanza amanzi, yenze kube lula ukuhlangana nokugeleza ukuze kususwe ukungcola emithonjeni yamanzi. Ukuguquguquka kwayo, ukuphumelela kwezindleko, kanye nezinzuzo zemvelo kuyenza ibe ithuluzi elibalulekile ekufuneni amanzi ahlanzekile naphephile. Ukuqonda ukubaluleka kwe-PAC ekuhlanzweni kwamanzi kugcizelela ukubaluleka kwayo ekubhekaneni nezinselele zekhwalithi yamanzi emhlabeni jikelele.
