Ukugcinwa KweMembrane Engangeni Manzi Futhi Ephefumulayo
Uma i-membrane igcinwa isikhathi eside, kufanele igcine ukusebenza kahle futhi ibe nenani lokusetshenziswa, ngakho-ke impilo ye-membrane engangeni manzi futhi ephefumulayo iyinkinga ebalulekile. Ngakho-ke, ukunakwa okukhethekile kufanele kukhokhwe kwisitoreji sangempela.
Ukulondolozwa kolwelwesi lwe-microfiltration olungangeni manzi futhi oluphefumulayo luhlukaniswe ngezindlela ezimbili: ukulondolozwa okumanzi kanye nokugcinwa okomile. Noma iyiphi indlela, inhloso ukuvimbela ulwelwesi ukuthi lungabi ne-hydrolyzed, ukuvimbela ukukhula nokuguguleka kwama-microorganisms, kanye nokuncipha nokuguqulwa kolwelwesi.
Isihluthulelo sokulondolozwa okumanzi ukugcina njalo i-membrane ebusweni nesisombululo sokulondoloza esimweni esimanzi. Ifomula elandelayo ingasetshenziselwa isixazululo sokulondoloza: amanzi: glycerin: formaldehyde = 79.5:20:0.5. Indima ye-formaldehyde ukuvimbela ukukhula nokukhiqizwa kabusha kwama-microorganisms ebusweni bolwelwesi nokuvimbela ukuguguleka kolwelwesi. Inhloso yokwengeza i-glycerin ukunciphisa indawo yokuqandisa yesisombululo sokulondoloza nokuvimbela ulwelwesi ukuba lonakaliswe ukuqhwa. I-formaldehyde esefomini ingathathelwa indawo amanye ama-fungicides afana ne-copper sulfate engenabungozi kulwelwesi. Izinga lokushisa lokugcina le-cellulose acetate membrane liyi-5-40 ° C kanye ne-PH = 4.5 ~ 5, kuyilapho izinga lokushisa lokugcina kanye ne-pH ye-non-cellulose acetate membrane ingaba banzi.
Ukulondolozwa Komile
Ama-microfiltration membranes angangeni manzi futhi aphefumulayo avame ukuhlinzekwa emakethe njengama-membrane omile ngoba kulula ukuwagcina nokuthutha. Ngaphezu kwalokho, ifilimu emanzi kufanele igcinwe ngendlela eyomile, futhi izindlela ezilandelayo kufanele zisetshenziswe ukucubungula ifilimu ngaphambi kokuqhubeka. Indlela eqondile yile: ulwelwesi lwe-cellulose acetate lungacwiliswa ku-50% ye-glycerin aqueous solution noma i-0.1% sodium lauryl sulfonate isixazululo samanzi izinsuku ezingu-5 kuya kwezi-6, futhi yomiswe kumswakama ohlobene nama-88%. I-polysulfone membrane ingamiswa ekamelweni lokushisa ngesisombululo se-10% ye-glycerin, i-sulfonated oil, i-polyethylene glycol, njll njenge-agent dehydrating. Ngaphezu kwalokho, ama-surfactants nawo anomphumela omuhle ekuvikeleni ama-pores efilimu ekuguqulweni.
Okwesibili, ukugcinwa nokugcinwa kwesistimu ye-membrane engenamanzi futhi ephefumulayo kufanele inakwe
Ukugcinwa nokugcinwa kwesistimu ye-membrane kufanele kugxile ezindabeni ezilandelayo.
① Ngokusho kolwelwesi oluhlukile, ukunaka okukhethekile kufanele kukhokhwe endaweni esetshenziswayo, ikakhulukazi izinga lokushisa nenani le-pH loketshezi olubalulekile, ngisho nokuqukethwe kwe-chlorine oketshezini olubalulekile.
② Uma uhlelo lwe-membrane lumiswa isikhathi esifushane, ukunakwa kufanele kukhokhwe ekugcinweni komswakama we-membrane, ngoba lapho ulwelwesi lwangaphandle lulahlekelwa amanzi, asikho isilinganiso sokulungisa, ama-membrane angangeni manzi futhi aphefumulayo azoncipha futhi akhubazeke, okuyinto. kuzonciphisa ukusebenza kwe-membrane.
③Uma ume, gwema ukuthintana noketshezi olugxile kakhulu.
④ Geza futhi ulondoloze ulwelwesi njalo ngoketshezi lokulungisa ukuze unciphise ukungcoliswa kolwelwesi.
⑤ Uma isetshenziswa, sebenza ngokuhambisana nezimo zokusebenza ezingamelana nesistimu ye-membrane ukuze ugweme ukugcwala ngokweqile.
