Ububiko bwa Amazi adashobora gukoreshwa na Membrane
Iyo membrane ibitswe igihe kirekire, igomba gukomeza gukora neza kandi ikagira agaciro, bityo ubuzima bwamazi adahumeka kandi ahumeka nikibazo cyingenzi. Kubwibyo, hagomba kwitabwaho cyane kububiko nyabwo.
Kubungabunga microfiltration membrane itagira amazi kandi ihumeka bigabanijwe muburyo bubiri: kubungabunga amazi no kubungabunga byumye. Ibyo ari byo byose, ikigamijwe ni ukubuza ururenda kuba hydrolyz, gukumira imikurire n’isuri bya mikorobe, no kugabanuka no guhindura imikorere.
Urufunguzo rwo kubungabunga amazi ni uguhora ugumisha hejuru ya membrane hamwe nigisubizo cyo kubungabunga muburyo butose. Inzira ikurikira irashobora gukoreshwa mugukemura igisubizo: amazi: glycerine: formaldehyde = 79.5: 20: 0.5. Uruhare rwa formaldehyde ni ukurinda imikurire n’imyororokere ya mikorobe hejuru y’ururenda no kwirinda isuri. Intego yo kongeramo glycerine ni ukugabanya aho gukonjesha igisubizo cyo kubungabunga no gukumira ururenda kwangirika no gukonja. Formaldehyde iri muri formula irashobora kandi gusimburwa nizindi fungiside nka sulfate y'umuringa itangiza ibyangiritse. Ubushyuhe bwo kubika selile ya selile ya selile ni 5-40 ° C na PH = 4.5 ~ 5, mugihe ubushyuhe bwo kubika hamwe na pH ya selile ya acetate ya selile irashobora kuba yagutse.
Kubungabunga Kuma
Microfiltration ya microfiltration idafite amazi kandi ihumeka akenshi itangwa kumasoko nkibibabi byumye kuko byoroshye kubika no gutwara. Byongeye kandi, firime itose igomba kubikwa muburyo bwumye, kandi uburyo bukurikira bugomba gukoreshwa mugutunganya firime mbere yo gukomeza. Uburyo bwihariye ni: selulose acetate membrane irashobora gushirwa mumazi ya glycerine 50% cyangwa umuti wa 0.1% sodium lauryl sulfonate wamazi muminsi 5 kugeza kuri 6, hanyuma ukumishwa nubushyuhe bugereranije bwa 88%. Indwara ya polysulfone irashobora gukama mubushyuhe bwicyumba hamwe nigisubizo cya 10% glycerine, amavuta ya sulfonate, polyethylene glycol, nibindi nkibikoresho byo kubura amazi. Byongeye kandi, surfactants nayo igira ingaruka nziza mukurinda imyenge ya firime guhinduka.
Icya kabiri, kubungabunga no gufata neza sisitemu idafite amazi kandi ihumeka neza igomba kwitabwaho
Kubungabunga no gufata neza sisitemu ya membrane bigomba kwibanda kubibazo bikurikira.
① Ukurikije ibice bitandukanye, hakwiye kwitabwaho byumwihariko ibidukikije, cyane cyane ubushyuhe nagaciro ka pH byamazi yibintu, ndetse nibirimo chlorine mumazi yibintu.
② Iyo sisitemu ya membrane ihagaritswe mugihe gito, hagomba kwitonderwa kugumana ubushuhe bwikibabi, kuko ubuso nibumara gutakaza amazi, ntaburyo bwo gukosora, imyanda idashobora gukoreshwa namazi ihumeka izagabanuka kandi ihindurwe, ibyo Kugabanya imikorere ya membrane.
HenIyo uhagaze, irinde guhura n'amazi menshi.
Gukaraba no kubungabunga buri gihe hamwe n'amazi yo kubungabunga kugirango ugabanye umwanda.
⑤ Mugukoresha, kora ukurikije imiterere yimikorere sisitemu ya membrane ishobora kwihanganira kugirango wirinde kurenza urugero.
