Gutunganya amazi yanduye: guhitamo hagati ya polyaluminum chloride na aluminium sulfate

Mu rwego rwo gutunganya amazi yanduye, polyaluminum chloride (PAC) na aluminium sulfate bikoreshwa cyane nkaimiti igabanya ubukana bw'amarasoHari itandukaniro mu miterere y'ibi bintu bibiri, bigatuma imikorere yabyo n'ikoreshwa ryabyo. Mu myaka ya vuba aha, PAC yagiye ikundwa buhoro buhoro kubera imikorere yayo myiza n'umuvuduko wayo. Muri iyi nkuru, turaganira ku itandukaniro riri hagati ya PAC na sulfate ya aluminiyumu mu gutunganya amazi yanduye kugira ngo bigufashe guhitamo neza.

Ubwa mbere, reka twige kuri polyaluminum chloride (PAC). Nk'umuyoboro wa polymer utagira umwimerere, PAC ifite ubushobozi bwo gushonga neza kandi ishobora gukora flocs vuba. Igira uruhare mu gushonga binyuze mu gukoresha amashanyarazi no gufata inshundura, kandi ikoreshwa hamwe na flocculant PAM kugira ngo ikureho neza imyanda mu mazi yanduye. Ugereranyije na aluminium sulfate, PAC ifite ubushobozi bwo gutunganya amazi neza kandi ifite ubuziranenge bwiza nyuma yo kuyasukura. Hagati aho, ikiguzi cyo gusukura amazi ya PAC kiri hasi ya 15%-30% ugereranyije na aluminium sulfate. Ku bijyanye no gukoresha alkalinity mu mazi, PAC ifite ikoreshwa rito kandi ishobora kugabanya cyangwa guhagarika gutera alkali agent.

Ikurikiraho ni sulfate ya aluminiyumu. Nk'umuti usanzwe wo gushonga, sulfate ya aluminiyumu inyuza ikanayivanga binyuze mu miyoboro ya aluminiyumu hidroksidi ikorwa na hydrolysis. Igipimo cyayo cyo gushonga ni gito cyane, ariko ikwiriye gukoreshwa mu gutunganya amazi yanduye ifite pH iri hagati ya 6.0-7.5. Ugereranyije na PAC, sulfate ya aluminiyumu ifite ubushobozi buke bwo kuyatunganya n'ubwiza bw'amazi meza, kandi ikiguzi cyo kuyasukura kiri hejuru cyane.

Ku bijyanye n'ingano z'imikorere, PAC na aluminium sulfate bifite akamaro gatandukanye gato; muri rusange PAC yoroshye kuyifata kandi ikora flocs vuba, ibyo bigatuma imikorere myiza yo kuyivura irushaho kuba myiza. Ku rundi ruhande, aluminium sulfate iratinda gushonga kandi ishobora gufata igihe kirekire kugira ngo ihure.

Sulfate ya aluminiyumubizagabanya pH n'ubucucike bw'amazi yavuwe, bityo soda cyangwa lime birakenewe kugira ngo bihagarike ingaruka. Umuti wa PAC umeze nk'aho udafite aho ubogamiye kandi nta kintu na kimwe gisaba ku kintu icyo ari cyo cyose kigabanya ubucucike (soda cyangwa lime).

Mu bijyanye no kubika, PAC na aluminium sulfate akenshi birahamye kandi byoroshye kubika no gutwara. Mu gihe PAC igomba gufungwa kugira ngo hirindwe ko ubushuhe bushobora kwinjiza cyangwa ngo ihure n'izuba.

Byongeye kandi, ukurikije uburyo bwo kwangirika, sulfate ya aluminiyumu yoroshye kuyikoresha ariko irushaho kwangirika. Mu guhitamo imiti igabanya ubukana bw'ibinyabutabire, ingaruka zishobora guterwa n'ibyo byombi ku bikoresho byo kuvura zigomba kwitabwaho byimazeyo.

Muri make,Polyaluminum Chloride(PAC) na aluminium sulfate bifite ibyiza n'ibibi byabyo mu gutunganya imyanda. Muri rusange, PAC igenda ihinduka coagulant isanzwe bitewe n'ubushobozi bwayo bwo hejuru, ubushobozi bwo gutunganya amazi yanduye vuba ndetse no kwihutisha pH. Ariko, aluminium sulfate iracyafite ibyiza bidasimburwa mu bihe bimwe na bimwe. Kubwibyo, mu gihe uhitamo coagulant, ibintu nk'ibikenewe nyabyo, ingaruka zo kuyitunganya n'igiciro bigomba kwitabwaho. Guhitamo coagulant ikwiye bizafasha kunoza imikorere yo gutunganya amazi yanduye.
