Yini eyenziwa yi-PAC ekuhlanzweni kwamanzi?

I-Polyaluminum chloride (I-PAC) idlala indima ebalulekile ezinqubweni zokwelashwa kwamanzi, isebenza njenge-coagulant kanye ne-flocculant ephumelelayo. Emkhakheni wokuhlanzwa kwamanzi, i-PAC isetshenziswa kabanzi ngenxa yokuguquguquka kwayo kanye nokusebenza kahle ekususeni ukungcola emithonjeni yamanzi. Le nhlanganisela yamakhemikhali ingumdlali obalulekile ezigabeni zokuqina kanye ne-flocculation, esiza ekuthuthukiseni ukusebenza kahle kwezitshalo zokwelashwa kwamanzi.

Ukuqina kwamanzi kuyisinyathelo sokuqala ekuphathweni kwamanzi, lapho i-PAC ifakwa khona emanzini angavuthiwe. Ama-ion e-aluminium ashajwe kahle ku-PAC aqeda ukushaja okungekuhle ezinhlayiyeni ezilenga emanzini, okubangela ukuba zihlangane ndawonye. Lezi zinhlayiya eziqinile zakha ama-aggregate amakhulu futhi asindayo, okwenza kube lula ukuthi zihlale emanzini ngesikhathi sezinqubo ezilandelayo. Inqubo yokuqina kwamanzi ibalulekile ekususeni ukungcola kwe-colloidal kanye nokulenga okungase kungahlungwa kalula.

Ukugoqeka kulandela ukugoqeka futhi kuhilela ukuxutshwa noma ukuxubana kwamanzi kancane ukuze kukhuthazwe ukwakheka kwama-floc amakhulu avela ezinhlayiyeni ezigoqekile. I-PAC iyasiza kulesi sigaba ngokunikeza amanye amashaja amahle, ikhuthaza ukushayisana kanye nokuhlangana kwezinhlayiya ukuze zakhe ama-floc amakhulu futhi aminyene. Lawa ma-floc ahlala kahle kakhulu ngesikhathi sokugoqeka, okufaka isandla emanzini acwebezelayo.

Enye yezinzuzo eziphawulekayo ze-PAC ekuphatheni amanzi ukuthi iyakwazi ukuzivumelanisa nezimo eziningi zekhwalithi yamanzi. Isebenza kahle kokubili ezindaweni ezine-acidic kanye ne-alkaline, okwenza ifanelekele ukwelapha imithombo yamanzi ehlukahlukene. Ngaphezu kwalokho, i-PAC iyasebenza ekuphatheni ukungcoliswa kwamanzi okushintshashintshayo futhi ingasetshenziswa ezindleleni ezahlukene zokwelashwa kwamanzi, okuhlanganisa ukwelashwa kwamanzi okuphuza, ukwelashwa kwamanzi ezimbonini, kanye nokwelashwa kwamanzi angcolile.

I-PAC idlala indima ebalulekile ezinqubweni zokwelashwa kwamanzi, yenza kube lula ukujiya kanye nokugoba ukuze kususwe ukungcola emithonjeni yamanzi. Ukuzivumelanisa nezimo kwayo, ukusebenza kahle kwezindleko, kanye nezinzuzo zemvelo kuyenza ibe ithuluzi elibalulekile ekufuneni ukutholakala kwamanzi ahlanzekile naphephile. Ukuqonda ukubaluleka kwe-PAC ekunakekelweni kwamanzi kugcizelela ukubaluleka kwayo ekubhekaneni nezinselele zekhwalithi yamanzi emhlabeni jikelele.
