Ingaba iPAC ingalukhukulisa njani udaka lwelindle?

Polyaluminium chloride(PAC) yi-coagulant edla ngokusetyenziswa kunyango lwamanzi amdaka ukuntywila amasuntswana amisiweyo, kubandakanywa nezo zifumaneka kudaka lwelindle.I-Flocculation yinkqubo apho amasuntswana amancinci emanzini ahlangana kunye ukuze enze amasuntswana amakhulu, anokususwa ngokulula ngakumbi emanzini.

Nantsi indlela iPAC enokuthi isetyenziswe ngayo ukuntywila ilindle elimdaka:

Ukulungiswa kwesisombululo sePAC:I-PAC iqhele ukubonelelwa ngolwelo okanye umgubo.Inyathelo lokuqala kukulungisa isisombululo sePAC ngokunyibilikisa umgubo ocoliweyo okanye ukuxutywa kolwelo emanzini.Ukugxininiswa kwePAC kwisisombululo kuya kuxhomekeka kwiimfuno ezithile zenkqubo yonyango.

Ukuxuba:IPACisisombululo ke sixutywe nodaka lwelindle.Oku kunokwenziwa ngeendlela ezahlukeneyo ngokuxhomekeke ekumisweni kwendawo yonyango.Ngokuqhelekileyo, isisombululo sePAC songezwa kwi-sludge kwi-tank yokuxuba okanye nge-dosing system.

Ukudibanisa:Emva kokuba isisombululo sePAC sixutywe kunye nodaka, iqala ukusebenza njenge-coagulant.I-PAC isebenza ngokunciphisa iintlawulo ezimbi kumasuntswana amisiweyo kudaka, ewavumela ukuba adibane kwaye enze ii-aggregates ezinkulu.

Ukuqukuqela:Njengoko i-sludge ephathwayo ye-PAC ihamba ngokukhawuleza okanye ukuxuba, amaqhekeza angathathi hlangothi aqala ukuhlangana ukuze enze iiflocs.Ezi flocs zinkulu kwaye zinzima kunamaqhekeza ngamanye, okwenza kube lula ukuhlalisa okanye ukuhlukana nesigaba solwelo.

Ukulungisa:Emva kwe-flocculation, i-sludge ivumelekile ukuba ihlale kwitanki yokumisa okanye i-clarifier.Iiflokhi ezinkulu zihlala phantsi kwetanki phantsi kwefuthe lomxhuzulane, zishiya ngasemva amanzi acacileyo phezulu.

Ukwahlula:Emva kokuba inkqubo yokumisa igqityiwe, amanzi acacisiweyo anokuthi ahlanjululwe okanye afakwe phezulu kwitanki yokumisa ukuze aphinde anyangwe okanye akhululwe.I-sludge ehleliweyo, ngoku i-denser kwaye i-compact ngakumbi ngenxa ye-flocculation, inokususwa ukusuka ezantsi kwetanki ukuze kuqhutywe okanye ukulahlwa.

Kubalulekile ukuqaphela ukuba impumelelo yePAC kuilindle elidadayoinokuxhomekeka kwizinto ezahlukeneyo ezifana nokuxinana kwePAC esetyenzisiweyo, i-pH yodaka, ubushushu, kunye neempawu zodaka ngokwalo.Ukwandiswa kwezi parameters ngokwesiqhelo kwenziwa ngovavanyo lwaselabhoratri kunye nolingo lokulinga ukuphumeza iziphumo zonyango ezinqwenelekayo.Ukongeza, ukuphathwa ngendlela eyiyo kunye nokudongwa kwePAC kubalulekile ukuze kuqinisekiswe unyango olusebenzayo nolungabizi kakhulu lodaka lwelindle.
