Mokhoa oa ho Filtration oa Ultrafiltration Membrane

Theknoloji ea "membrane" ea Ultrafiltration ke theknoloji ea karohano ea membrane e thehiloeng ho tlhahlobo le ho sefa, ka phapang ea khatello e le eona matla a ka sehloohong a khannang. Molao-motheo oa eona o ka sehloohong ke ho etsa phapang e nyenyane ea khatello mahlakoreng ka bobeli a lera la filtration, e le ho fana ka matla a hore limolek'hule tsa metsi li kene ka har'a li-pores tse nyenyane tsa membrane ea filtration, le ho thibela lit?ila tse ka lehlakoreng le leng la lera la filtration, e netefatsang hore boleng ba metsi ka mora ho hlwekiswa bo kopana le maemo a amehang.
Ka kakaretso, lera la ultrafiltration le ka aroloa ka membrane ea khatello ea ka hare ea ultrafiltration le membrane ea ka ntle ea khatello ea ultrafiltration ho latela mekhoa e fapaneng ea ho kenya metsi. Theknoloji ea ka hare ea khatello ea ultrafiltration membrane e qala ka ho kenya likhoerekhoere ka har'a fiber e sekoti, ebe e sutumelletsa phapang ea khatello ho etsa hore limolek'hule tsa metsi li phunyeletse ka ntle ho lera 'me lit?ila li lule li le ka har'a lera le se nang letho. Theknoloji ea kantle ea khatello ea ultrafiltration membrane e fapane le khatello ea ka hare, ka mor'a khatello ea khatello, limolek'hule tsa metsi li kenella ka har'a lesela le se nang letho la fiber le lit?ila tse ling li koetsoe ka ntle.
Lera la Ultrafiltration le phetha karolo ea bohlokoa ts'ebelisong ea theknoloji ea membrane ea ultrafiltration. Lera la Ultrafiltration le entsoe haholo ka polyacrylonitrile, polyvinylidene fluoride, polyvinyl chloride, polysulfone le lisebelisoa tse ling, thepa ea lisebelisoa tsena e khetholla lit?obotsi tsa lera la ultrafiltration. Ts'ebetsong ea 'nete ea kopo, basebelisi ba amehang ba hloka ho nahana ka botlalo mocheso, khatello ea ts'ebetso, tlhahiso ea metsi, phello ea tlhoekiso ea metsi le lintlha tse ling ho eketsa phello ea theknoloji ea lera la ultrafiltration, e le ho hlokomela poloko le ho sebelisoa bocha ha mehloli ea metsi.
Hona joale, hangata ho na le mekhoa e 'meli ea ho hloekisa ha ho sebelisoa theknoloji ea lera la ultrafiltration: lefu la ho qetela le ho sefa ka ho phalla.
Sefa se shoeleng se boetse se bitsoa ho sefa ka botlalo. Ha taba e emisitsoeng, turbidity, colloid content metsing a tala e le tlase, joalo ka metsi a pompo, metsi a ka tlas'a lefat?e, metsi a holim'a metsi, joalo-joalo, kapa ho na le moralo o tiileng oa tsamaiso ea pele ho phekolo pele ho ultrafiltration, ultrafiltration e ka sebelisa mokhoa o feletseng oa ho hloekisa. ts'ebetso. Nakong ea ho sefa ka ho feletseng, metsi 'ohle a feta ka holim'a lera ho fetoha tlhahiso ea metsi,' me lintho tsohle tse silafatsang li kenngoa holim'a lera. E hloka ho nt?oa ka har'a lera ka ho hlatsuoa khafetsa moeeng, ho hlatsuoa ka metsi le ho hlatsuoa pele, le ho hloekisa lik'hemik'hale khafetsa.
Ho phaella tabeng ea ho sefa ka mokhoa o shoeleng, cross-flow filtration hape ke mokhoa o tloaelehileng oa ho hloekisa. Ha lintho tse emisitsoeng le lets'oants'o la metsi a tala li phahame, joalo ka mererong e tsosolositsoeng ea t?ebeliso ea metsi, mokhoa oa ho sefa oa ho phalla hangata o sebelisoa. Nakong ea filthara ea phallo ea phallo, karolo ea metsi a kenang e feta ka holim'a lera hore e be tlhahiso ea metsi, 'me karolo e' ngoe e nt?oa e le metsi a kopaneng, kapa e hatelloa hape ebe e khutlisetsoa lera ka har'a mokhoa oa ho potoloha. Cross-flow filtration e etsa hore metsi a potoloha a sa khaotse holim'a lera. Lebelo le phahameng la metsi le thibela ho bokellana ha likaroloana holim'a lera, ho fokotsa t?usumetso ea polarization ea mahloriso, le ho fokotsa ho silafala ka potlako ha lera.
Leha thekenoloji ea lera la ultrafiltration e na le melemo e ke keng ea lekanngoa ts'ebetsong ea ts'ebeliso, ha ho bolele hore ke theknoloji ea membrane ea ultrafiltration feela e ka sebelisoang e le 'ngoe ho hloekisa metsi a silafetseng ts'ebetsong ea kalafo ea mehloli ea metsi a silafetseng. Ha e le hantle, ha ba tobane le bothata ba ho hloekisa mehloli ea metsi a silafetseng, basebetsi ba amehang ba ka leka ho kopanya mekhoa e fapaneng ea phekolo. Ho ntlafatsa ka katleho ts'ebetso ea kalafo ea mehloli ea metsi a silafetseng, e le hore boleng ba mehloli ea metsi ka mor'a ho phekoloa bo ka tiisetsoa ka katleho.
Ka lebaka la lisosa tse fapaneng tsa t?ilafalo ea metsi, ha se mehloli eohle ea metsi a silafetseng e loketseng phekolo e t?oanang ea t?ilafalo. Basebetsi ba lokela ho ntlafatsa bohlale ba motsoako oa theknoloji ea membrane ea ultrafiltration, 'me ba khethe mokhoa o nepahetseng ka ho fetisisa oa phekolo bakeng sa tlhoekiso ea metsi. Ke ka tsela ena feela, molemong oa ho netefatsa ts'ebetso ea ts'ebetso ea ts'ilafalo ea metsi, moo boleng ba metsi a metsi a silafetseng bo ka ntlafatsoang ka mor'a ho hloekisoa.
