Poly Aluminiyam chloride(PAC) yinkomponi yemichiza esetyenziswa kakhulu kunyango lwamanzi kunye namanzi amdaka ngenxa yempumelelo yawo ekususeni ungcoliseko. Indlela yokusebenza kwayo ibandakanya amanyathelo aphambili aliqela anegalelo ekucocweni kwamanzi.
Okokuqala, iPAC isebenza njengecoagulant kwiinkqubo zokucocwa kwamanzi. I-Coagulation yinkqubo yokunciphisa ukuqina kwamasuntswana e-colloidal kunye nokumiswa emanzini, okubangela ukuba adibane kwaye enze amasuntswana amakhulu abizwa ngokuba ziiflocs. I-PAC ifezekisa oku ngokunciphisa iintlawulo ezingalunganga kumphezulu we-colloidal particles, ezivumela ukuba zihlangane kwaye zenze i-flocs ngenkqubo ebizwa ngokuba yi-charge neutralization. Ezi flocs ke kulula ukuzisusa ngokusebenzisa iinkqubo zokuhluza ezilandelayo.
Ukubunjwa kwee-flocs kubalulekile ekususeni iintlobo ezahlukeneyo zokungcola emanzini. I-PAC isusa ngokufanelekileyo izinto eziqinileyo ezimisiweyo, ezinje ngamasuntswana odongwe, intlenga yentlenga, kunye nezinto eziphilayo, ngokuzibandakanya kwiiflocs. Ezi ziqina zinqunyanyiswayo zinokuba negalelo kumanzithinzithi, nto leyo ewenza abonakale enamafu okanye amnyama. Ngokudibanisa la masuntswana kwiiflocs ezinkulu, iPAC iququzelela ukususwa kwazo ngexesha lentlenga kunye neenkqubo zokuhluza, okukhokelela kumanzi acacileyo.
Ngaphaya koko, iPAC inceda ekususeni izinto ezinyityilisiweyo zezinto eziphilayo kunye nemixube ebangela umbala emanzini. Izinto eziphilayo ezinyibilikisiweyo, ezifana ne-humic kunye ne-fulvic acid, zinokudlulisela incasa ezingemnandanga kunye nevumba emanzini kwaye zinokusabela ngezibulali-ntsholongwane zenze imveliso eyingozi yokubulala iintsholongwane. I-PAC inceda ukujiya kunye nokubhengeza ezi khompawundi eziphilayo kumphezulu weentlambo ezibunjiweyo, ngaloo ndlela zinciphisa ukuxinana kwazo kumanzi acociweyo.
Ukongeza kwi-organic matter, iPAC inokususa ngokufanelekileyo izingcolisi ezahlukeneyo emanzini. Ezi zingcolisi zinokubandakanya iintsimbi ezinzima, ezifana ne-arsenic, ilothe, kunye ne-chromium, kunye neeanion ezithile ezifana ne-phosphate kunye ne-fluoride. Imisebenzi yePAC ngokwenza i-insoluble metal hydroxide precipitates okanye ngokubhengeza i-ion zetsimbi kumphezulu wayo, ngaloo ndlela inciphisa ukuxinana kwabo kumanzi acociweyo ukuya kumanqanaba ahlangabezana nemigangatho yolawulo.
Ngaphezu koko, iPAC ibonisa inzuzo ngaphezu kwezinye iicoagulants eziqhele ukusetyenziswa kunyango lwamanzi, njenge-aluminium sulfate (i-alum). Ngokungafaniyo ne-alum, i-PAC ayitshintshi kakhulu i-pH yamanzi ngexesha lenkqubo yokudibanisa, enceda ukunciphisa imfuno yeekhemikhali zohlengahlengiso lwe-pH kunye nokunciphisa iindleko zizonke zonyango. Ukongeza, iPAC ivelisa amadaka ambalwa xa kuthelekiswa ne-alum, ekhokelela kumaxabiso aphantsi okulahla kunye neempembelelo zokusingqongileyo.
Lilonke, iPoly Aluminiyam Chloride (PAC) sisidibanisi esisebenza kakuhle kakhulu esidlala indima ebalulekileyo ekususeni izingcolisi ezahlukeneyo emanzini. Ukukwazi kwayo ukukhuthaza i-coagulation, i-flocculation, i-sedimentation, kunye neenkqubo ze-adsorption ziyenza ibe yinto ebalulekileyo kwiinkqubo zokunyanga kwamanzi kwihlabathi jikelele. Ngokuququzelela ukususwa kwezinto eziqinileyo ezimisiweyo, izinto eziphilayo ezinyibilikileyo, iikhompawundi ezibangela umbala, kunye nezinto ezingcolileyo, iPAC inceda ukuvelisa amanzi okusela acocekileyo, acacileyo nakhuselekileyo ahlangabezana nemigangatho yokulawula. Ukusebenza kwayo kweendleko, ukusetyenziswa lula, kunye nempembelelo encinci kwi-pH yamanzi yenza ukuba kube yinto ekhethiweyo yokunyanga izityalo ezifuna izisombululo ezithembekileyo nezizinzileyo zokucocwa kwamanzi.
