I-PAC ingaluhambisa kanjani udaka lwendle?

I-Polyaluminium chloride(i-PAC) i-coagulant evame ukusetshenziswa ekuhlanzeni amanzi angcolile ukuze kuntante izinhlayiya ezimisiwe, okuhlanganisa nalezo ezitholakala kudaka lwendle.I-Flocculation inqubo lapho izinhlayiya ezincane emanzini zihlangana ndawonye ukuze zakhe izinhlayiya ezinkulu, ezingase zikhishwe kalula emanzini.

Nansi indlela i-PAC engasetshenziswa ngayo ukuhambisa udaka lwendle:

Ukulungiswa kwesixazululo se-PAC:I-PAC ivamise ukunikezwa iwuketshezi noma impushana.Isinyathelo sokuqala ukulungisa isisombululo se-PAC ngokuncibilikisa ifomu eliyimpuphu noma ukuhlambulula uketshezi oluwuketshezi emanzini.Ukugxila kwe-PAC esixazululweni kuzoncika ezidingweni ezithile zenqubo yokwelapha.

Ukuxuba:II-PACIsixazululo sibe sesixutshwa nodaka lwendle.Lokhu kungenziwa ngezindlela ezihlukahlukene kuye ngokuthi isikhungo sokwelapha sinjani.Imvamisa, isixazululo se-PAC siyengezwa kudaka ethangini lokuxuba noma ngohlelo lokudosa.

I-coagulation:Uma isisombululo se-PAC sesixubene nodaka, siqala ukusebenza njenge-coagulant.I-PAC isebenza ngokunciphisa izindleko ezingezinhle ezinhlayiyeni ezimisiwe odaka, ezivumela ukuthi zihlangane futhi zakhe ama-aggregate amakhulu.

I-Flocculation:Njengoba udaka olulahlwe yi-PAC lunyakaziswa kancane noma luxutshwa, izinhlayiya ezingathathi hlangothi ziqala ukuhlangana zenze ama-flocs.Lezi zinhlayiya zinkulu futhi zisinda kunezinhlayiya ngazinye, okwenza kube lula ukuzinza noma ukuhlukana nesigaba soketshezi.

Iyalungisa:Ngemuva kwe-flocculation, i-sludge ivunyelwe ukuhlala ku-tank yokuxazulula noma i-clarifier.Ama-flocs amakhulu ahlala phansi ethangini ngaphansi kwethonya lamandla adonsela phansi, eshiya ngemuva kwamanzi acacisiwe phezulu.

Ukwehlukana:Uma inqubo yokumisa isiqediwe, amanzi acacisiwe anganqanyulwa noma aphonswe phezulu ethangini lokumisa ukuze aqhubeke nokwelashwa noma akhishwe.Udaka olulungisiwe, manje oluminyene futhi luminyene ngenxa yokugobhoza, lungasuswa ngaphansi kwethangi ukuze kuqhutshekwe nokucubungula noma ukulahlwa.

Kubalulekile ukuqaphela ukuthi ukusebenza ngempumelelo kwe-PAC kuflocculating indle sludgekungancika ezintweni ezihlukahlukene njengokugxilwa kwe-PAC esetshenzisiwe, i-pH yodaka, izinga lokushisa, nezici zodaka ngokwalo.Ukuthuthukiswa kwale mingcele ngokuvamile kwenziwa ngokuhlolwa kwaselabhorethri kanye nokuhlola kwesikali sokulinga ukuze kuzuzwe imiphumela yokwelashwa efiselekayo.Ukwengeza, ukuphathwa ngendlela efanele kanye nomthamo we-PAC kubalulekile ukuze kuqinisekiswe ukwelashwa okuphumelelayo nokungabizi kodaka lwendle.
