I-PAC ingawususa kanjani udoti wendle ogelezayo?

I-Polyaluminum chloride(PAC) iyi-coagulant evame ukusetshenziswa ekwelapheni amanzi amdaka ukuze kufakwe izinhlayiya ezilengayo, okuhlanganisa nalezo ezitholakala odakeni lwendle. I-Flocculation inqubo lapho izinhlayiya ezincane emanzini zihlangana khona ukuze zakhe izinhlayiya ezinkulu, ezingasuswa kalula emanzini.

Nansi indlela i-PAC engasetshenziswa ngayo ukuhlanza udaka lwendle:

Ukulungiswa kwesisombululo se-PAC:I-PAC ivame ukunikezwa ngesimo soketshezi noma sempuphu. Isinyathelo sokuqala ukulungiselela isixazululo se-PAC ngokuncibilikisa isimo soketshezi noma ngokuncibilikisa isimo soketshezi emanzini. Ukuhlushwa kwe-PAC esixazululweni kuzoncika ezidingweni ezithile zenqubo yokwelapha.

Ukuxuba:II-PACIsixazululo sibe sesixutshwa nodaka lwendle. Lokhu kungenziwa ngezindlela ezahlukene kuye ngokuthi indawo yokwelapha ihlelwe kanjani. Ngokuvamile, isixazululo se-PAC singezwa odakeni olusethangini lokuxuba noma ngohlelo lokulinganisa.

Ukujiya:Uma ikhambi le-PAC selixutshwe nodaka, liqala ukusebenza njenge-coagulant. I-PAC isebenza ngokunciphisa ama-negative charges ezinhlayiyeni ezilengayo odakeni, okuzivumela ukuthi zihlangane futhi zakhe ama-aggregate amakhulu.

Ukukhukhuleka:Njengoba udaka oluphathwe nge-PAC luxutshwa noma luxutshwa kancane, izinhlayiya ezingasebenzi kahle ziqala ukuhlangana ukuze zakhe ama-floc. Lawa ma-floc makhulu futhi anzima kunezinhlayiya ngazinye, okwenza kube lula ukuzinza noma ukuzihlukanisa nesigaba soketshezi.

Ukuxazulula:Ngemva kokugobhoza, udaka luyavunyelwa ukuthi luhlale ethangini lokuzinza noma emshinini wokucwenga. Ama-floc amakhulu ahlala phansi ethangini ngaphansi kwethonya lamandla adonsela phansi, ashiye amanzi acwengekile phezulu.

Ukuhlukana:Uma inqubo yokuzinza isiqediwe, amanzi acwengekile angakhishwa noma akhishwe phezulu kwethangi lokuzinza ukuze kulungiswe noma kukhishwe okunye. Udaka oluzinzile, manje oluqinile futhi oluncane ngenxa yokugobhoza, lungasuswa phansi kwethangi ukuze kuqhutshekwe nokucutshungulwa noma kulahlwe.

Kubalulekile ukuqaphela ukuthi ukusebenza kahle kwe-PAC ku-udaka lwendle olugelezayokungancika ezintweni ezahlukahlukene njengokuhlushwa kwe-PAC esetshenzisiwe, i-pH yodaka, izinga lokushisa, kanye nezici zodaka ngokwalo. Ukwenziwa ngcono kwalezi zinhlaka kuvame ukwenziwa ngokuhlolwa kwelebhu kanye nokuhlolwa kwesilinganiso sokuhlola ukuze kufezwe imiphumela yokwelashwa oyifunayo. Ngaphezu kwalokho, ukuphathwa kahle kanye nokulinganisa i-PAC kubalulekile ukuqinisekisa ukuphathwa kodaka lwendle okuphumelelayo nokungabizi.
