I-Poly Aluminium Chloride ikususa kanjani ukungcola emanzini?

I-Poly Aluminium chloride(i-PAC) iyinhlanganisela yamakhemikhali esetshenziswa kakhulu ekwelapheni amanzi namanzi angcolile ngenxa yokuphumelela kwayo ekukhipheni ukungcola. Indlela yayo yokusebenza ibandakanya izinyathelo ezimbalwa ezibalulekile ezifaka isandla ekuhlanzweni kwamanzi.

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

Ukwakheka kwama-flocs kubalulekile ekukhipheni ukungcola okuhlukahlukene emanzini. I-PAC isusa ngempumelelo izinto eziqinile ezimisiwe, njengezinhlayiya zobumba, udaka, nezinto eziphilayo, ngokuzifaka ku-flocs. Lezi zinto eziqinile ezimisiwe zingaba nomthelela ekuvuvukeni kwamanzi, zenze kubonakale kuguqubele noma kumnyama. Ngokuhlanganisa lezi zinhlayiya zibe ama-flocs amakhulu, i-PAC yenza kube lula ukususwa kwazo ngesikhathi sedimentation kanye nezinqubo zokuhlunga, okuholela emanzini acacile.

Ngaphezu kwalokho, i-PAC isiza ekukhipheni izinto eziphilayo ezincibilikisiwe nezinhlanganisela ezidala umbala emanzini. Izinto eziphilayo ezincibilikisiwe, njenge-humic ne-fulvic acid, zinganikeza ukunambitheka okungajabulisi namaphunga emanzini futhi zingase zihlangane nezibulala-magciwane zenze imikhiqizo eyingozi yokubulala amagciwane. I-PAC isiza ukujiya kanye nokukhangisa lezi zinhlanganisela eziphilayo phezu kwama-flocs akhiwe, ngaleyo ndlela yehlise ukugxila kwazo emanzini ahlanzekile.

Ngokungeziwe kuzinto eziphilayo, i-PAC ingaphinda isuse ngempumelelo ukungcola okuhlukahlukene okungaphili emanzini. Lokhu kungcola kungase kuhlanganise izinsimbi ezisindayo, njenge-arsenic, i-lead, ne-chromium, kanye nama-anion athile afana ne-phosphate ne-fluoride. I-PAC isebenza ngokwakha i-insoluble metal hydroxide precipitates noma ngokukhangisa ama-ion ensimbi endaweni yayo, ngaleyo ndlela yehlise ukugxila kwawo emanzini ahlanzekile abe amazinga ahlangabezana nezindinganiso zokulawula.

Ngaphezu kwalokho, i-PAC ibonisa izinzuzo ngaphezu kwamanye ama-coagulant avame ukusetshenziswa ekuhlanzeni amanzi, njenge-aluminium sulfate (i-alum). Ngokungafani ne-alum, i-PAC ayishintshi kakhulu i-pH yamanzi phakathi nenqubo yokuhlangana, esiza ukunciphisa isidingo samakhemikhali okulungisa i-pH futhi yehlise izindleko zizonke zokwelashwa. Ukwengeza, i-PAC ikhiqiza ama-sludge ambalwa uma kuqhathaniswa ne-alum, okuholela ezindlekweni eziphansi zokulahla kanye nomthelela wemvelo.

Sekukonke, i-Poly Aluminium Chloride (PAC) iyi-coagulant esebenza kahle kakhulu edlala indima ebalulekile ekususeni ukungcola okuhlukahlukene emanzini. Ikhono layo lokugqugquzela ukuhlangana, ukugeleza, ukubola, kanye nezinqubo ze-adsorption kuyenza ibe yingxenye ebalulekile ezinhlelweni zokuhlanza amanzi emhlabeni jikelele. Ngokwenza kube lula ukukhishwa kwezinto eziqinile ezimisiwe, izinto eziphilayo ezincibilikisiwe, izinhlanganisela ezibangela umbala, nokungcola okungaphili, i-PAC isiza ukukhiqiza amanzi okuphuza ahlanzekile, acacile, naphephile ahlangabezana nezindinganiso zokulawula. Ukusebenza kahle kwezindleko, ukusebenziseka kalula, kanye nomthelela omncane ku-pH yamanzi kwenza kube ukukhetha okuncanyelwayo kwezitshalo zokuhlanza amanzi ezifuna izixazululo ezinokwethenjelwa nezisimeme zokuhlanzwa kwamanzi.
