I-Poly Aluminium Chloride isusa kanjani ukungcola emanzini?

I-Poly Aluminium Chloride(PAC) iyinhlanganisela yamakhemikhali esetshenziswa kabanzi ekwelapheni amanzi namanzi angcolile ngenxa yokusebenza kwayo kahle ekususeni ukungcola. Indlela esebenza ngayo ihilela izinyathelo eziningana ezibalulekile ezifaka isandla ekuhlanzweni kwamanzi.

Okokuqala, i-PAC isebenza njenge-coagulant ezinqubweni zokwelashwa kwamanzi. I-coagulation inqubo yokuphazamisa ukuzinza kwezinhlayiya ze-colloidal kanye nokumiswa emanzini, okubangela ukuthi zihlangane futhi zakhe izinhlayiya ezinkulu ezibizwa ngokuthi ama-floc. I-PAC ifinyelela lokhu ngokunciphisa izindleko ezingezinhle ebusweni bezinhlayiya ze-colloidal, ezivumela ukuthi zihlangane futhi zakhe ama-floc ngenqubo ebizwa ngokuthi i-charge neutralization. Lawa ma-floc abese kuba lula ukuwasusa ngezinqubo zokuhlunga ezilandelayo.

Ukwakheka kwama-floc kubalulekile ekususweni kwezinto ezihlukahlukene ezingcolisayo emanzini. I-PAC isusa ngempumelelo izinto eziqinile ezilengayo, njengezinhlayiya zobumba, udaka, nezinto eziphilayo, ngokuzifaka kuma-floc. Lezi zinto eziqinile ezilengayo zingafaka isandla ekungcoleni kwamanzi, zenze kubonakale sengathi kunamafu noma kumnyama. Ngokuhlanganisa lezi zinhlayiya zibe ama-floc amakhulu, i-PAC yenza kube lula ukususwa kwazo ngesikhathi senqubo yokufakwa kwenhlabathi kanye nokuhlunga, okuholela emanzini acwebezelayo.

Ngaphezu kwalokho, i-PAC iyasiza ekususweni kwezinto eziphilayo ezincibilikisiwe kanye namakhemikhali abangela umbala emanzini. Izinto eziphilayo ezincibilikisiwe, njenge-humic kanye ne-fulvic acid, zingadlulisela ukunambitheka okungathandeki kanye nephunga emanzini futhi zingase zisabela ngezibulali-magciwane ukuze zakhe imikhiqizo eyingozi yokubulala amagciwane. I-PAC iyasiza ekuhlanganiseni nasekumunceni la makhemikhali emvelo phezu kwama-floc akhiwe, ngaleyo ndlela inciphise ukuhlushwa kwawo emanzini aphathwe kahle.

Ngaphezu kwezinto eziphilayo, i-PAC ingasusa ngempumelelo ukungcola okuhlukahlukene okungakhiqizi emanzini. Lokhu kungcola kungafaka izinsimbi ezisindayo, njenge-arsenic, i-lead, ne-chromium, kanye nama-anion athile njenge-phosphate ne-fluoride. I-PAC isebenza ngokwakha ama-precipitate ensimbi angancibiliki noma ngokumunca ama-ion ensimbi ebusweni bayo, ngaleyo ndlela inciphise ukuhlushwa kwawo emanzini aphathwe ngendlela ehlangabezana nezindinganiso ezilawulayo.

Ngaphezu kwalokho, i-PAC ibonisa izinzuzo ngaphezu kwezinye izinto ezihlanganisa amanzi ezivame ukusetshenziswa ekuphatheni amanzi, njenge-aluminium sulfate (alum). Ngokungafani ne-alum, i-PAC ayishintshi kakhulu i-pH yamanzi ngesikhathi senqubo yokujiya, okusiza ukunciphisa isidingo samakhemikhali okulungisa i-pH futhi kunciphisa izindleko zokwelashwa. Ngaphezu kwalokho, i-PAC ikhiqiza udaka oluncane uma kuqhathaniswa ne-alum, okuholela ezindleleni zokulahla eziphansi kanye nemiphumela emvelweni.

Sekukonke, i-Poly Aluminium Chloride (PAC) iyi-coagulant esebenza kahle kakhulu edlala indima ebalulekile ekususweni kwezinto ezihlukahlukene ezingcolisayo emanzini. Amandla ayo okukhuthaza ukujiya, ukugobhoza, ukuthungwa, kanye nezinqubo zokumunca kwenza kube yingxenye ebalulekile ezinhlelweni zokwelashwa kwamanzi emhlabeni jikelele. Ngokwenza kube lula ukususwa kwezinto eziqinile ezimisiwe, izinto eziphilayo ezincibilikisiwe, amakhemikhali abangela umbala, kanye nezinto ezingcolisayo ezingaphili, i-PAC isiza ekukhiqizeni amanzi okuphuza ahlanzekile, acacile, futhi aphephile ahlangabezana nezindinganiso ezisemthethweni. Ukusebenza kahle kwezindleko zayo, ukusetshenziswa kwayo kalula, kanye nomthelela omncane ku-pH yamanzi kwenza kube ukukhetha okuthandwayo kwezitshalo zokwelapha amanzi ezifuna izixazululo ezithembekile neziqhubekayo zokuhlanzwa kwamanzi.
