Izakhi ezihlukahlukene ze-membrane zisetshenziswa embonini yokwelapha amanzi, kanti ezivame kakhulu ulwelwesi lwe-ultrafiltration kanye nolwelwesi lwe-osmosis oluhlehlayo. Kokubili ulwelwesi lwe-ultrafiltration kanye nolwelwesi lwe-osmosis oluhlehlayo luyinto esebenzisekayo emishinini yokwelapha amanzi. Usayizi wembotshana we-reverse osmosis membrane yi-1/100 kuphela yalowo we-ultrafiltration membrane, ngakho-ke i-osmosis ehlehlayo imishini yokwelapha amanzi ingasusa ngempumelelo izinsimbi ezisindayo, izibulala-zinambuzane, i-chloroform, nokunye ukungcola kwamakhemikhali ngekhwalithi yamanzi. Izihlanzi zamanzi ze-Ultrafiltration azinamandla. I-ultrafiltration water purifier ingasusa izinhlayiya ezingcolisayo namagciwane, angasuswa yi-osmosis ehlehlayo.
1. Umehluko wezakhiwo phakathi kwe-ultrafiltration membrane kanye nolwelwesi lwe-osmosis ehlehlayo:
Ulwelwesi olungemuva lwe-osmosis luwulwelwesi lokwenziwa olukwazi ukungena kancane olunezici ezithile ezenziwe ngokulingisa ulwelwesi lwebhayoloji olungene kancane. Ngokuvamile kwenziwa ngezinto ze-polymer. Ububanzi be-membrane pores ngokuvamile buphakathi kuka-0.5 no-10 nm, futhi ukuvuthwa kuhlobene nesakhiwo samakhemikhali solwelwesi ngokwalo.
I-Ultrafiltration membrane iwuhlobo lwe-microporous filtration membrane enobukhulu obufanayo bembotshana kanye nebanga losayizi wembotshana olinganiselwe we-0.001-0.02 microns. Ukusebenzisa ingcindezi efanele ohlangothini olulodwa lolwelwesi kungahlola ama-molecule e-solute amancane kunosayizi wembotshana ukuze ahlukanise izinhlayiya ezinesisindo se-molecule engaphezu kuka-500 Daltons (amayunithi obunzima be-athomu) kanye nosayizi wezinhlayiyana ezingaphezu kuka-10 nanometers. I-ultrafiltration membrane ingenye ye-membrane yokuqala yokuhlukanisa i-polymer eyakhiwe, futhi idivayisi ye-ultrafiltration yenziwa yizimboni ngawo-1960.
2. Ubuhle nokubi kwe-ultrafiltration membrane kanye ne-reverse osmosis membrane:
Izinzuzo ze-ultrafiltration: ngokuvamile awekho amaphampu, akukho ukusetshenziswa kwamandla, azikho izinkinga zokuphepha zikagesi; amalunga ambalwa, umfutho wamanzi ophansi, izinga lokuhluleka eliphansi uma kuqhathaniswa, kanye namathuba okuvuza kwamanzi; isakhiwo esilula kanye nentengo ephansi;
Ukungalungi: umphumela omubi wokukhipha ukungcola kwamakhemikhali emanzini; umthelela omubi ezigamekweni ezikhethekile zokuhlinzekwa kwamanzi; ukunambitheka okuncane kwamanzi; engakwazi ukunciphisa ubulukhuni bamanzi, njengokuqina okuphezulu kwamanzi kampompi, isitsha samanzi abilayo singangcoliswa.
I-Ultrafiltration membrane ingasusa ama-macromolecules, ama-colloid, amaprotheni, izinhlayiya, njll esixazululweni, futhi inezici zokucindezela okuphansi, ukukhiqizwa kwamanzi amakhulu, nokusebenza okulula. Ngokuhlola umphumela wokwelapha wedivaysi ye-fiber ultrafiltration membrane engenalutho yokuhlanzwa okujulile kwamanzi, kufakazelwa ukuthi ulwelwesi lwe-ultrafiltration idivayisi yokuhlanza amanzi ingaqeda ngempumelelo ukungcoliswa kwesibili kwamanzi kunethiwekhi yamapayipi futhi ithuthukise ikhwalithi yamanzi.
Izinzuzo zemishini yokwelapha amanzi ehlanekezela i-osmosis: izinga lamanzi aphephile, lingasusa ngempumelelo zonke izinhlobo zokungcola okuyingozi kukhwalithi yamanzi; umphumela ongcono wezigameko ezikhethekile zokuhlinzekwa kwamanzi; ukunambitheka okungcono kwamanzi; inganciphisa ngempumelelo ubulukhuni bekhwalithi yamanzi, futhi isitsha samanzi abilayo akulula ukusikala;
Ukungalungi: amaphampu, ukusetshenziswa kwamandla, izindaba zokuphepha zikagesi; amalunga amaningi, umfutho wamanzi ophakeme, izinga eliphezulu lokuhluleka, kanye namathuba okuvuza kwamanzi; isakhiwo esiyinkimbinkimbi, kanye nenani elibiza kakhulu.
3. Ububanzi bokusetshenziswa kwe-ultrafiltration membrane kanye nolwelwesi oluhlehla lwe-osmosis:
Ububanzi bokusebenza be-reverse osmosis membrane
Ugesi, i-petrochemical, insimbi nensimbi, i-electronics, imithi, ukudla nesiphuzo, ukuphathwa kukamasipala kanye nokuvikelwa kwemvelo kanye neminye imikhakha, ekukhishweni kukasawoti emanzini olwandle namanzi anosawoti, amanzi okuphakelayo kwe-boiler, amanzi ahlanzekile ezimbonini kanye nebanga le-elekthronikhi ukulungiswa kwamanzi ahlanzekile, ukuphuza ukukhiqizwa kwamanzi ahlanzekile, ukwelashwa kwamanzi angcolile kanye Inqubo yokuhlukanisa ekhethekile idlala indima ebalulekile.
Uhlelo lokusebenza lwe-membrane ye-ultrafiltration
Amanzi ahlanzekile namanzi e-ultrapure asetshenziswa njenge-reverse osmosis pretreatment kanye nokwelashwa kwetheminali yamanzi e-ultrapure ekulungiseni; amanzi ezimboni asetshenziselwa ukuhlukanisa amagciwane, imithombo yokushisa, ama-colloid, ukungcola okumisiwe, kanye ne-macromolecular organics; amanzi okuphuza, ukuhlanzwa kwamanzi amaminerali; ukuvutshelwa, imboni yokulungiselela ama-Enzyme kanye nokugxila embonini yezemithi, ukuhlanzwa, nokucaciswa; ukugxila kwejusi nokuhlukaniswa; ubhontshisi wesoya, ubisi, imboni kashukela, iwayini, ijusi yetiye, uviniga, njll. ukwahlukanisa, ukugxilisa ingqondo nokucaciswa; Amanzi angcolile ezimbonini kanye nokuhlanzwa nokutholwa kwendle; Ukubuyiselwa kopende we-electrophoretic.
