I-PAC ingayicoca njani inkunkuma yamanzi amdaka?

I-Polyaluminum chloride(PAC) sisicoagulant esisetyenziswa kakhulu kunyango lwamanzi amdaka ukufunxa amasuntswana axhonyiweyo, kuquka lawo afumaneka kwidaka lendle. Ukufunxa yinkqubo apho amasuntswana amancinci emanzini adibana khona ukuze enze amasuntswana amakhulu, anokususwa lula emanzini.

Nantsi indlela i-PAC engasetyenziswa ngayo ukuthulula udaka lwelindle:

Ukulungiswa kwesisombululo se-PAC:I-PAC idla ngokunikezelwa ngendlela engamanzi okanye engumgubo. Inyathelo lokuqala kukulungiselela isisombululo se-PAC ngokunyibilikisa ifomu engumgubo okanye ngokuxuba ifomu engamanzi emanzini. Uxinzelelo lwe-PAC kwisisombululo luya kuxhomekeka kwiimfuno ezithile zenkqubo yonyango.

Ukuxuba:II-PACemva koko isisombululo sixutywa nodaka lwamanzi amdaka. Oku kungenziwa ngeendlela ezahlukeneyo kuxhomekeke kwindlela ebekwe ngayo indawo yokucoca. Ngokwesiqhelo, isisombululo se-PAC songezwa kudaka olukwitanki yokuxuba okanye ngenkqubo yokulinganisa.

Ukujiya:Xa isisombululo se-PAC sixutywe nodaka, siqala ukusebenza njenge-coagulant. I-PAC isebenza ngokunciphisa ii-negative charges kumasuntswana axhonyiweyo kudaka, ivumela ukuba zihlangane kwaye zenze ii-aggregates ezinkulu.

Ukuqunjelwa kwesikhumba:Njengoko udaka oluphathwe ngePAC luxutywa okanye luxutywa kancinci, amasuntswana angasebenziyo aqala ukudibana ukuze enze ii-flocs. Ezi flocs zikhulu kwaye zinzima kuneesuntswana ezizimeleyo, nto leyo eyenza kube lula ukuzinza okanye ukwahlukana nesigaba solwelo.

Ukulungiselela:Emva kokutyibilika, udaka luyavunyelwa ukuba luhlale kwitanki yokutyibilika okanye kwi-clarifier. Iiflocs ezinkulu zihlala ezantsi kwetanki phantsi kwempembelelo yomxhuzulane, zishiya amanzi acwengileyo phezulu.

Ukwahlukana:Nje ukuba inkqubo yokuzinza igqityiwe, amanzi acacisiweyo angasuswa okanye akhutshwe phezulu kwitanki yokuzinza ukuze kulungiswe okanye kukhutshwe amanzi. Udaka oluzinzileyo, ngoku oluxineneyo kwaye oluncinci ngenxa yokuqunjelwa, lungasuswa ezantsi kwitanki ukuze kuqhutyekwe okanye kulahlwe.

Kubalulekile ukuqaphela ukuba ukusebenza kakuhle kwe-PACudaka lwelindle oluhambahambayoinokuxhomekeka kwizinto ezahlukeneyo ezifana noxinzelelo lwe-PAC esetyenzisiweyo, i-pH yodaka, ubushushu, kunye neempawu zodaka ngokwalo. Ukulungiswa kwezi parameters kudla ngokwenziwa ngovavanyo lwelabhoratri kunye novavanyo lwesikali sovavanyo ukuze kufezekiswe iziphumo zonyango ezifunwayo. Ukongeza, ukuphathwa ngokufanelekileyo kunye nokulinganisa i-PAC kubalulekile ukuqinisekisa unyango olufanelekileyo nolungabizi kakhulu lodaka lwamanzi amdaka.
