Ultrafiltration membrane tekinoroji tekinoroji yekuparadzanisa tekinoroji yakavakirwa pakuongorora uye kusefa, ine kudzvanywa musiyano seyo huru yekutyaira simba. Nheyo yayo huru ndeyekugadzira diki diki mutsauko pamativi ese ari maviri efiltration membrane, kuitira kuti ipe simba rekuti mamorekuru emvura apinde nepakati pemapores madiki efiltration membrane, uye kuvhara tsvina kune rumwe rutivi rwefiltration membrane, iyo inova nechokwadi chekuti mhando yemvura mushure mekurapwa inosangana nezvinodiwa.
Kazhinji, ultrafiltration membrane inogona kukamurwa kuita yemukati yekumanikidza ultrafiltration membrane uye yekunze kumanikidza ultrafiltration membrane zvinoenderana nenzira dzakasiyana dzekupinza mvura. Iyo yemukati yekumanikidza ultrafiltration membrane tekinoroji inotanga yapinza tsvina mugomba fiber, uye yobva yasundira musiyano wekumanikidza kuti mamorekuru emvura apinde kunze kwe membrane uye tsvina irambe iri mugomba fiber membrane. Iyo yekunze yekumanikidza ultrafiltration membrane tekinoroji inopesana nekumanikidza kwemukati, mushure mekumanikidza kusunda, mamorekuru emvura anopinda mukati megomba fiber membrane uye kumwe kusvibiswa kunovharirwa kunze.
Ultrafiltration membrane inoita basa rakakosha mukushandiswa kweiyo ultrafiltration membrane tekinoroji. Ultrafiltration membrane inonyanya kugadzirwa ne polyacrylonitrile, polyvinylidene fluoride, polyvinyl chloride, polysulfone uye zvimwe zvinhu, zvimiro zvezvinhu izvi zvinotarisisa hunhu hwe ultrafiltration membrane. Muchiitiko chaicho chekushandisa, vashandisi vakakodzera vanofanirwa kutarisisa zvizere tembiricha, kudzvanywa kwekushanda, goho remvura, kuchenesa mvura uye zvimwe zvinhu kuti uwedzere mhedzisiro yeultrafiltration membrane tekinoroji, kuitira kuti vaone kuchengetedza uye kudzokorodza zviwanikwa zvemvura.
Parizvino, pane kazhinji nzira mbiri dzekusefa mukushandiswa kweultrafiltration membrane tekinoroji: kufa kwekupedzisira kusefa uye kuyambuka-kuyerera kusefa.
Kusefa kwakafa kunonzi zvakare kusefa kuzere. Kana iyo yakamiswa nyaya, turbidity, colloid yemukati mumvura mbishi yakadzikira, senge pombi mvura, pasi pevhu, pamusoro pemvura, nezvimwewo, kana pane yakasimba dhizaini ye pre-kurapa system isati yaitwa ultrafiltration, ultrafiltration inogona kushandisa yakazara filtration mode operation. Munguva yekusefa kwakazara, mvura yese inopfuura nepa membrane pamusoro kuti ive kugadzirwa kwemvura, uye zvese zvinosvibisa zvinobatwa pa membrane pamusoro. Inoda kuburitswa kubva muzvikamu zvemembrane kuburikidza nekukweshwa kwemhepo nguva dzose, kugezeswa kwemvura kumashure uye kufefetera mberi, uye kuchenesa kemikari nguva dzose.
Pamusoro pekufa-kuguma kusefa, kuyambuka-kuyerera kwesefa zvakare iri yakajairika nzira yekusefa. Kana iyo yakamiswa uye turbidity mumvura mbishi yakakwira, senge mumapurojekiti akadzokororwa ekushandisazve mvura, cross-flow filtration mode inowanzo shandiswa. Munguva yekuyambuka-kuyerera kusefa, chikamu chemvura inopinza inopfuura nepakati pe membrane kuti ive kugadzirwa kwemvura, uye chimwe chikamu chinoburitswa semvura yakanyungudika, kana kuti inodzvanywa zvakare uye yozodzoserwa kune membrane mukati meyekutenderera modhi. Cross-flow filtration inoita kuti mvura itenderere nguva dzose pamusoro pe membrane. Kukwirisa kwemvura kunodzivirira kuunganidzwa kwezvikamu zviri pamusoro pe membrane, kunoderedza simba rekugadzirisa polarization, uye kuderedza kukurumidza kusvibiswa kwe membrane.
Kunyangwe tekinoroji ye ultrafiltration membrane ine mabhenefiti asingaenzaniswi mukuita kwekushandisa, hazvireve kuti chete ultrafiltration membrane tekinoroji inogona kushandiswa yega kuchenesa mvura yakasvibiswa mukugadziriswa kwemvura yakasvibiswa. Muchokwadi, kana takatarisana nedambudziko rekusvibiswa kwezviwanikwa zvemvura, vashandi vakakodzera vanogona kuedza kusanganisa akasiyana matekinoroji ekurapa. Kunyatso kuvandudza kushandiswa kwehutano hwemvura yakasvibiswa yemvura, kuitira kuti hutano hwemvura mushure mekurapa hugone kuvimbiswa.
Nekuda kwezvikonzero zvakasiyana-siyana zvekusvibiswa kwemvura, hazvisi zvese zviwanikwa zvemvura zvakasvibiswa zvakakodzerwa nekurapa kusvibiswa kwakafanana. Vashandi vanofanirwa kuvandudza kunzwisisika kwekubatanidzwa kwe ultrafiltration membrane tekinoroji, uye sarudza nzira yakakodzera yekurapa yekuchenesa mvura. Nenzira iyi chete, pachigadziro chekuvimbisa kushanda kwekugadzirisa kusvibiswa kwemvura, iyo mhando yemvura yemvura yakasvibiswa inogona kuvandudzwa mushure mekucheneswa.
