Ngabe wenzani ekwelashweni kwamanzi?

Polyaluminum chloride (Isinyathelo) Idlala indima ebalulekile ezinhlanganweni zokwelashwa kwamanzi, isebenza njenge-coulant esebenzayo ne-flecculant. Endaweni yokuhlanza kwamanzi, i-PAC isetshenziswa kabanzi ngenxa yokusebenza okuhlukahlukene nokusebenza kahle ekususeni ukungcola emithonjeni yamanzi. Le nhlanganisela yamakhemikhali isidlali esibalulekile ekubambeni kanye naseziteshini ze-floccution, isiza ukuthuthukisa ukusebenza kahle kwezitshalo zokwelashwa kwamanzi.

Ukuhlangana kuyisinyathelo sokuqala sokwelashwa kwamanzi, lapho i-PAC ingezwe khona emanzini aluhlaza. I-aluminium ions ekhokhiswa nge-Aluminium ion ku-PAC yezezimali ezingezinhle ezinhlasweni ezimisiwe emanzini, ibangele ukuba bahlangane. Lezi zinhlayiya ezihlanganisiwe zihlanganisa ama-aggregate amakhulu futhi asindayo, okwenza kube lula ngabo ukuhlalisa emanzini ngezindlela ezalandela. Inqubo yokubumbana ibalulekile ekususeni ukungcola okuhlangene nokumiswa okumisiwe okungenzeka kungahlungwa kalula.

I-Floccution ilandela ukugeleza futhi ifaka phakathi ukushukumisa okumnene noma ukuxubana kwamanzi ukukhuthaza ukwakheka kwama-flocs amakhulu avela ezinkineni ezihlanganisiwe. I-PAC AIDS kulesi sigaba ngokunikeza amanye amacala amahle, ukukhuthaza ukushayisana kanye nokuhlanganiswa kwezinhlayiya ukwakha okukhulu futhi okude kakhulu. Lawa ama-flocs axazulula ngempumelelo ngokwengeziwe ngesikhathi sedimentation, efaka isandla emanzini acwengekileyo.

Enye yezinzuzo eziphawuleka ze-PAC ekwelashweni kwamanzi ukuzivumelanisa nezimo zayo ezinhlobonhlobo zezimo ezisezingeni lamanzi. Kwenza kahle ezindaweni ezine-acidic ne-alkali, okwenza kube lula ukwelapha imithombo yamanzi ehlukahlukene. Ngokwengeziwe, i-PAC iyasebenza ekusingatheni ukuguquguquka kwamanzi okushintshashintshayo futhi ingasetshenziswa ezinhlelweni ezahlukahlukene zokwelashwa kwamanzi, kubandakanya ukuphuza ukwelashwa kwamanzi, ukwelashwa kwamanzi ezimbonini, kanye nokwelashwa kwamanzi angcolile.

I-PAC idlala indima ebaluleke kakhulu ezinqubweni zokwelashwa kwamanzi, yenza lula ukuphoqelelwa kanye ne-floccation ukususa ukungcola emithonjeni yamanzi. Ukuzivumelanisa nezimo, ukusebenza kwezindleko, kanye nezinzuzo zemvelo kwenza kube yithuluzi elibalulekile ekufuneni izinsiza zamanzi ahlanzekile neliphephile. Ukuqonda ukubaluleka kwe-PAC ekukweleni kwamanzi kugcizelela ukubaluleka kwayo ekubhekaneni nezinselelo zekhwalithi yamanzi emhlabeni wonke.
