Nigute ushobora guhangana na RO membrane ikosa

Kwangirika kwa Membrane bivuga ibintu bidasubirwaho aho uduce, uduce duto twa colloidal, cyangwa gukemura macromolecules mugisubizo cyibiryo uhuye na membrane adsorb hanyuma ukabitsa hejuru ya membrane cyangwa pore bitewe nubusabane bwumubiri cyangwa imiti hamwe na membrane, cyangwa polarisiyasi yibitekerezo itera ibisubizo bimwe na bimwe birenze ubukana bwabyo hamwe nubukonje bukabije, kandi bikagabanuka mubunini bwibibyimba cyangwa ibibyimba.

Kwanduza mikorobe

1 Impamvu zo gushingwa

Kwanduza mikorobe bivuga ibintu aho ibinyabuzima byegeranya kuri interineti y'amazi, bityo bikagira ingaruka ku mikorere ya sisitemu. Izi mikorobe ziragwira kandi zigakura hifashishijwe ibice bya osmose bihindagurika nkibitwara nintungamubiri ziva mu gice cy’amazi cyibanze cya osmose ihindagurika, bigakora urwego rwa biofilm hejuru yubuso bwa osmose. Ibi biganisha ku kwiyongera byihuse itandukaniro ryumuvuduko hagati yinjira n’isohoka rya sisitemu ya osmose ihindagurika, igabanuka ryihuse ry’umusaruro w’amazi n’igabanuka ry’amazi, hamwe n’umwanda w’amazi y’ibicuruzwa. Biofilm igizwe na mikorobe irashobora mu buryo butaziguye (binyuze mu bikorwa bya enzymatique) cyangwa mu buryo butaziguye (binyuze muri pH yaho cyangwa kugabanya ubushobozi) itesha agaciro polymers ya membrane cyangwa ibindi bice bigize osmose yibice, bikaviramo igihe gito cyo kubaho kwa membrane, kwangirika kwimiterere yimiterere, ndetse no kunanirwa kwa sisitemu.

2) Uburyo bwo kugenzura

Uburyo bwo kurwanya umwanda w’ibinyabuzima bushobora kugerwaho hifashishijwe ubudahwema cyangwa rimwe na rimwe kwanduza no kwanduza amazi yinjira. Ibikoresho byo kuboneza urubyaro bigomba gushyirwaho amazi mabi yakusanyirijwe hejuru no munsi y'ubutaka, kandi hagomba kongerwamo fungiside ya chlorine. Igipimo muri rusange gishingiye kubintu bya chlorine bisigaye mubishobora kuba birenze 1mg / L.

Kwangiza imiti

1) Impamvu zo gushingwa

Impamvu zikunze gutera umwanda w’imiti ni ugushyira igipimo cya karubone mu bice bigize membrane, ibyo bikaba ahanini biterwa no kudakoresha nabi, sisitemu yo kubuza ibipimo bituzuye, no guhagarika ikoreshwa rya inibitori mu gihe cyo gukora. Niba bitamenyekanye mugihe gikwiye, ikibazo cyo kongera umuvuduko wimikorere, kongera itandukaniro ryumuvuduko, nigabanuka ryumusaruro wamazi bizaba muminsi mike. Niba igipimo cyatoranijwe kibuza guhuza amazi cyangwa igipimo kidahagije, gupima imbere muri membrane nabyo bizagaragara. Gupima byoroheje imbere yibice bya membrane birashobora gusubizwa mumikorere yabyo binyuze mugusukura imiti, kandi mugihe gikomeye, birashobora kandi gutuma ibintu bimwe na bimwe byanduye bikabije.

2) Uburyo bwo kugenzura

Uburyo bwo kugenzura kugirango wirinde kwipimisha imbere muri membrane ni ukubanza guhitamo igipimo cyiza cya osmose kibuza inhibitori kubwamazi meza ya sisitemu, no kumenya urugero rwiza. Icya kabiri, komeza igenzura rya sisitemu yo gukuramo, ukurikiranire hafi impinduka zifatika mubipimo byimikorere, kandi uhite umenya icyateye ibintu bidasanzwe. Mubyongeyeho, ibintu byinshi bya Fe3 + mumazi ahanini biterwa na sisitemu y'imiyoboro. Kubwibyo, imiyoboro ya pulasitike itondekanye igomba gukoreshwa uko bishoboka kwose imiyoboro ya sisitemu, harimo imiyoboro y’amazi, kugirango igabanye Fe3 +.

Guhagarika ibintu byangiritse no kwanduza umwanda

1) Impamvu zo gushingwa

Ibice byahagaritswe hamwe na colloide nibintu byingenzi bifunga imiterere ya osmose membrane, kandi nimpamvu nyamukuru yo kurenga SDI isohoka (indangagaciro yubucucike). Bitewe no gutandukanya amasoko y'amazi n'uturere, hariho itandukaniro rikomeye mubice bigize uduce twahagaritswe na colloide. Ibice byingenzi bigize amazi y’ubutaka adahumanye n’amazi maremare ni bagiteri, ibumba, silika ya siloidal, okiside ya fer, ibicuruzwa bya acide humic, hamwe nogukora cyane muburyo bwa artile ya coagulants na coagulants (nkumunyu wicyuma, umunyu wa aluminium, nibindi) muri sisitemu yo kwitegura. Byongeye kandi, imvura yatewe no guhuza polymers zuzuye neza mumazi mbisi hamwe nubunini bwikigereranyo cyangiza nabi muri sisitemu ya osmose nayo ni imwe mubitera umwanda.

2) Uburyo bwo kugenzura

Iyo ibinini byahagaritswe biri mumazi mbisi arenze 70mg / L, coagulation, ibisobanuro, hamwe nuburyo bwo kubishungura; Iyo ibintu byahagaritswe biri mumazi mbisi bitarenze 70mg / L, filtration ya coagulation ikoreshwa muburyo bwo kwitegura; Iyo ibinini byahagaritswe biri mumazi mbisi bitarenze 10mg / L, uburyo bukoreshwa bwo kuyungurura. Byongeye kandi, microfiltration cyangwa ultrafiltration nuburyo bwiza bwo kuvura membrane uburyo bwo kuvura ibintu hamwe n’ibinyabuzima bidashobora gushonga byagaragaye vuba aha. Irashobora gukuraho ibintu byose byahagaritswe, bagiteri, colloide nyinshi, hamwe n’ibinyabuzima kidashobora gukama, kandi ni inzira nziza yo kubanza kuvura sisitemu ya osmose.
