I-Poly Aluminium Chloride isusa njani izinto ezingcolisayo emanzini?

I-Poly Aluminium Chloride(PAC) yikhemikhali esetyenziswa kakhulu ekunyangweni kwamanzi namanzi amdaka ngenxa yokusebenza kwayo ekususeni izinto ezingcolisayo. Indlela esebenza ngayo ibandakanya amanyathelo aliqela abalulekileyo anegalelo ekucoceni amanzi.

Okokuqala, i-PAC isebenza njenge-coagulant kwiinkqubo zonyango lwamanzi. I-coagulation yinkqubo yokuphazamisa ukuzinza kwee-colloidal particles kunye ne-suspensions emanzini, okubangela ukuba zihlangane kwaye zenze ii-particles ezinkulu ezibizwa ngokuba zii-flocs. I-PAC ifezekisa oku ngokunciphisa ii-negative charges kumphezulu wee-colloidal particles, ezivumela ukuba zihlangane kwaye zenze ii-flocs ngenkqubo ebizwa ngokuba yi-charge neutralization. Ezi flocs ke kulula ukuzisusa ngeenkqubo zokucoca ezilandelayo.

Ukwakheka kwee-flocs kubalulekile ekususweni kwezinto ezahlukeneyo ezingcolisayo emanzini. I-PAC isusa ngokufanelekileyo izinto eziqinileyo ezixhonyiweyo, ezifana namasuntswana odongwe, i-silt, kunye nezinto eziphilayo, ngokuzifaka kwii-flocs. Ezi zinto ziqinileyo ezixhonyiweyo zinokuba negalelo ekungcoleni kwamanzi, okwenza abonakale efumile okanye emdaka. Ngokuhlanganisa ezi nxalenye zibe zii-flocs ezinkulu, i-PAC yenza kube lula ukususwa kwazo ngexesha leenkqubo zokuhluza kunye nokuhluza, nto leyo ephumela kumanzi acacileyo.

Ngaphezu koko, i-PAC inceda ekususeni izinto eziphilayo ezinyibilikisiweyo kunye neekhompawundi ezibangela umbala emanzini. Izinto eziphilayo ezinyibilikisiweyo, ezifana ne-humic kunye ne-fulvic acids, zinokufaka incasa engathandekiyo kunye nevumba emanzini kwaye zinokusabela kunye nezibulali-ntsholongwane ukuze zenze iimveliso eziyingozi zokubulala iintsholongwane. I-PAC inceda ekujijeni nasekufunxeni ezi khompawundi ze-organic kumphezulu wee-flocs ezenziweyo, ngaloo ndlela zinciphisa uxinano lwazo emanzini acociweyo.

Ukongeza kwizinto eziphilayo, i-PAC inokususa ngempumelelo izinto ezahlukeneyo ezingcolisayo emanzini. Ezi zinto zingcolisayo zinokubandakanya iisinyithi ezinzima, ezifana ne-arsenic, i-lead, kunye ne-chromium, kunye nee-anions ezithile ezifana ne-phosphate kunye ne-fluoride. I-PAC isebenza ngokwenza ii-precipitates ze-metal hydroxide ezinganyibilikiyo okanye ngokufunxa ii-ion zesinyithi kumphezulu wazo, ngaloo ndlela zinciphisa uxinzelelo lwazo emanzini acociweyo ukuya kumanqanaba ahlangabezana nemigangatho emiselweyo.

Ngaphezu koko, i-PAC ibonisa iingenelo ngaphezu kwezinye izinto ezixuba amanzi ezisetyenziswa kakhulu ekucoceni amanzi, ezifana ne-aluminium sulfate (alum). Ngokungafaniyo ne-alum, i-PAC ayitshintshi kakhulu i-pH yamanzi ngexesha lenkqubo yokuxuba amanzi, nto leyo enceda ekunciphiseni imfuneko yeekhemikhali zokulungisa i-pH kwaye inciphise iindleko zizonke zonyango. Ukongeza, i-PAC ivelisa udaka oluncinci xa kuthelekiswa ne-alum, nto leyo ekhokelela ekuncipheni kweendleko zokulahla kunye nempembelelo yokusingqongileyo.

Ngokubanzi, iPoly Aluminium Chloride (PAC) yi-coagulant esebenza kakuhle kakhulu edlala indima ebalulekileyo ekususweni kwezinto ezahlukeneyo ezingcolisayo emanzini. Amandla ayo okukhuthaza ukujiya, ukuqunjelwa, ukutyibilika, kunye neenkqubo zokufunxa amanzi kuyenza ibe yinxalenye ebalulekileyo kwiinkqubo zonyango lwamanzi kwihlabathi liphela. Ngokuququzelela ukususwa kwezinto eziqinileyo ezixhonyiweyo, izinto eziphilayo ezinyibilikisiweyo, iikhompawundi ezibangela umbala, kunye nezinto ezingcolisayo ezingaphiliyo, i-PAC inceda ukuvelisa amanzi okusela acocekileyo, acacileyo, nakhuselekileyo ahlangabezana nemigangatho emiselweyo. Ukusebenza kakuhle kweendleko, ukulula kokusetyenziswa, kunye nempembelelo encinci kwi-pH yamanzi kwenza ukuba ibe lukhetho olukhethwayo kwizityalo zonyango lwamanzi ezifuna izisombululo ezithembekileyo nezizinzileyo zokucocwa kwamanzi.
