Gutunganya amazi mabi: guhitamo hagati ya chloride polyaluminium na sulfate ya aluminium

Mu rwego rwo gutunganya amazi mabi, polyoruminium chloride (PAC) na sulfate ya aluminium ikoreshwa cyane nkacoagulants. Hariho itandukaniro mumiterere yimiti yibi bikoresho byombi, bivamo imikorere yabyo no kuyishyira mubikorwa. Mu myaka yashize, PAC yagiye itoneshwa buhoro buhoro kubera kuvura neza no kwihuta. Muri iki kiganiro, tuzaganira ku itandukaniro riri hagati ya PAC na aluminium sulfate mu gutunganya amazi mabi kugirango tugufashe guhitamo neza.

Ubwa mbere, reka twige ibijyanye na chloride polyaluminium (PAC). Nka organic organique polymer coagulant, PAC ifite solubilité nziza kandi irashobora gukora flocs byihuse. Ifite uruhare runini binyuze mu kutabogama amashanyarazi no gufata inshundura, kandi ikoreshwa ifatanije na flocculant PAM kugirango ikureho umwanda mumazi mabi. Ugereranije na aluminium sulfate, PAC ifite imbaraga zo gutunganya hamwe n’amazi meza nyuma yo kwezwa. Hagati aho, ikiguzi cyo kweza amazi ya PAC kiri munsi ya 15% -30% ugereranije na sulfate ya aluminium. Kubijyanye no kunywa alkalineite mumazi, PAC ifite ibyo ikoresha kandi irashobora kugabanya cyangwa guhagarika inshinge za alkaline.

Ibikurikira ni sulfate ya aluminium. Nka coagulant gakondo, aluminium sulfate adsorbs kandi igahumanya imyanda ikoresheje aluminium hydroxide colloide ikorwa na hydrolysis. Igipimo cyacyo cyo gushonga ni gito, ariko birakwiriye gutunganya amazi mabi hamwe na pH ya 6.0-7.5. Ugereranije na PAC, sulfate ya aluminium ifite ubushobozi buke bwo gutunganya no gutunganya amazi meza, kandi ikiguzi cyo kweza amazi ni kinini.

Kubireba ibipimo bikora, PAC na aluminium sulfate bifite porogaramu zitandukanye; PAC mubisanzwe biroroshye kubyitwaramo no gukora flocs byihuse, bitezimbere uburyo bwo kuvura. Ku rundi ruhande, sulfate ya aluminium, itinda kuri hydrolyze kandi irashobora gufata igihe kirekire kugira ngo ihuze.

Aluminium sulfatebizagabanya pH na alkanilite yamazi yatunganijwe, bityo soda cyangwa lime birakenewe kugirango bitesha agaciro ingaruka. Igisubizo cya PAC cyegereye kutabogama kandi ntagisabwa kubintu byose bitesha agaciro (soda cyangwa lime).

Kubijyanye no kubika, PAC na aluminium sulfate mubisanzwe birahagaze kandi byoroshye kubika no gutwara. Mugihe PAC igomba gufungwa kugirango irinde kwangirika kwizuba hamwe nizuba.

Mubyongeyeho, duhereye kubitekerezo bya ruswa, aluminium sulfate iroroshye gukoresha ariko irabora cyane. Mugihe uhisemo coagulants, ingaruka zishobora kuba zombi kubikoresho byo kuvura zigomba gutekerezwa byuzuye.

Muri make,Polyoruminium Chloride(PAC) na aluminium sulfate bifite ibyiza byayo nibibi byo gutunganya imyanda. Muri rusange, PAC igenda ihinduka buhoro buhoro bitewe nubushobozi bwayo bwinshi, ubushobozi bwo gutunganya amazi mabi yihuse hamwe n’imihindagurikire ya pH. Nyamara, sulfate ya aluminium iracyafite ibyiza bidasubirwaho mubihe bimwe. Kubwibyo, mugihe uhisemo coagulant, ibintu nkibisabwa nyabyo, ingaruka zo kuvura nigiciro bigomba kwitabwaho. Guhitamo coagulant ibereye bizafasha kunoza imikorere yo gutunganya amazi mabi.
