Njira Yosefera ya Ultrafiltration Membrane

Ukadaulo wa membrane wa Ultrafiltration ndiukadaulo wolekanitsa wa membrane kutengera kuwunika ndi kusefera, ndikusiyana kwapanikizidwe ngati mphamvu yayikulu yoyendetsera. Mfundo yake yaikulu ndi kupanga kusiyana kwapang'onopang'ono kumbali zonse ziwiri za filtration membrane, kuti apereke mphamvu kwa mamolekyu a madzi kuti adutse ma pores ang'onoang'ono a filtration membrane, ndi kutsekereza zonyansa kumbali ina ya filtration nembanemba, zomwe zimatsimikizira kuti madzi akumwa pambuyo pa chithandizo akukumana ndi zofunikira.
Nthawi zambiri, nembanemba ya ultrafiltration imatha kugawidwa mu nembanemba yamkati yamphamvu ya ultrafiltration ndi nembanemba yakunja yamphamvu ya ultrafiltration motengera njira zosiyanasiyana zolowera madzi. The mkati kuthamanga ultrafiltration nembanemba luso poyamba jekeseni zimbudzi mu dzenje CHIKWANGWANI, ndiyeno amakankhira kusiyana kuthamanga kuti mamolekyu madzi kulowa mu nembanemba ndi zosafunika kukhala mu dzenje CHIKWANGWANI nembanemba. Ukadaulo wakunja waukadaulo wa ultrafiltration membrane ndi wosiyana ndi kukakamiza kwamkati, pambuyo pakukankhira, mamolekyu amadzi amalowa mu nembanemba yopanda kanthu ndipo zonyansa zina zimatsekedwa kunja.
Ultrafiltration nembanemba imagwira ntchito yofunika kwambiri pakugwiritsa ntchito ukadaulo wa ultrafiltration membrane. Ultrafiltration nembanemba makamaka zopangidwa polyacrylonitrile, polyvinylidene fluoride, polyvinyl kolorayidi, polysulfone ndi zipangizo zina, katundu wa zipangizo kudziwa makhalidwe a ultrafiltration nembanemba. M'njira yeniyeni yogwiritsira ntchito, ogwira ntchito oyenerera ayenera kuganizira mozama kutentha, kuthamanga kwa ntchito, kutulutsa madzi, kuyeretsa madzi ndi zinthu zina kuti apititse patsogolo luso la ultrafiltration nembanemba, kuti azindikire kupulumutsa ndi kubwezeretsanso madzi.
Pakalipano, pali njira ziwiri zosefera pakugwiritsa ntchito ukadaulo wa ultrafiltration membrane: kusefera kwakufa ndi kusefera kwapakati.
Kusefa kwakufa kumatchedwanso kusefa kwathunthu. Pamene nkhani inaimitsidwa, turbidity, colloid zili m'madzi yaiwisi ndi otsika, monga madzi apampopi, pansi pa nthaka, pamwamba madzi, etc., kapena pali dongosolo okhwima dongosolo pre-mankhwala pamaso ultrafiltration, ultrafiltration angagwiritse ntchito zonse kusefera mode. ntchito. Pa kusefedwa kwathunthu, madzi onse amadutsa pamwamba pa nembanemba kuti apange madzi, ndipo zoipitsa zonse zimatsekeredwa pamwamba pa nembanemba. Iyenera kutulutsidwa kuchokera ku nembanemba kudzera pakutsuka mpweya nthawi zonse, kutsuka madzi m'mbuyo ndi kutsogolo, komanso kuyeretsa mankhwala nthawi zonse.
Kuphatikiza pa kusefera kwakufa, kusefera kwapakati ndi njira yodziwika bwino yosefera. Pamene zinthu zoimitsidwa ndi turbidity m'madzi osaphika ndizokwera, monga mapulojekiti obwezeretsanso madzi, njira yosefera yodutsa nthawi zambiri imagwiritsidwa ntchito. Panthawi yosefera, gawo lina la madzi olowera limadutsa pa membrane kuti lipange madzi, ndipo gawo lina limatulutsidwa ngati madzi okhazikika, kapena amapanikizidwanso ndikubwerera ku nembanemba mkati mwa njira yozungulira. Kusefera kwapakati kumapangitsa kuti madzi azizungulira mosalekeza pa nembanemba pamwamba. Kuthamanga kwamadzi kumalepheretsa kudzikundikira kwa particles pamwamba pa nembanemba, kumachepetsa mphamvu ya ndende polarization, ndi kuchepetsa kuipitsidwa kofulumira kwa nembanemba.
Ngakhale teknoloji ya ultrafiltration nembanemba ili ndi ubwino wosayerekezeka pogwiritsira ntchito, sizikutanthauza kuti teknoloji yokha ya ultrafiltration ingagwiritsidwe ntchito yokha kuyeretsa madzi oipitsidwa pokonza madzi oipitsidwa. M'malo mwake, akakumana ndi vuto la kukonza kwa madzi oipitsidwa, ogwira ntchito oyenerera amatha kuyesa kuphatikiza njira zosiyanasiyana zamankhwala. Kupititsa patsogolo bwino chithandizo chamankhwala a madzi oipitsidwa, kuti ubwino wa madzi pambuyo pa chithandizo ukhoza kutsimikiziridwa bwino.
Chifukwa cha zifukwa zosiyanasiyana za kuipitsidwa kwa madzi, si madzi onse oipitsidwa omwe ali oyenera kuyeretsedwa mofanana. Ogwira ntchito akuyenera kuwongolera kulingalira kwa kuphatikiza kwaukadaulo wa ultrafiltration nembanemba, ndikusankha njira yoyenera kwambiri yochizira madzi. Pokhapokha, pamaziko owonetsetsa kuti madzi owonongeka akuyenda bwino, momwe madzi oipitsidwa angapitirire patsogolo pambuyo pa kuyeretsedwa.
