Izakhi ezihlukahlukene ze-membrane zisetshenziswa embonini yokwelapha amanzi, futhi 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, nezinye izinto ezingcolisa amakhemikhali 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 ukupesheleka kancane olunezici ezithile ezenziwe ngokulingisa ulwelwesi lwebhayoloji olungene kancane.Ngokuvamile zenziwe ngezinto ze-polymer.Ububanzi be-membrane pores ngokuvamile buphakathi kuka-0.5 no-10 nm, futhi ukungena kwamanzi kuhlobene nesakhiwo samakhemikhali selwelwesi ngokwalo.
I-Ultrafiltration membrane iwuhlobo lwe-microporous filtration membrane enobukhulu obufanayo bembotshana kanye nebanga losayizi wembotshana olinganiselwe we-0.001-0.02 microns.Ukusebenzisa ukucindezela okufanele ohlangothini olulodwa lolwelwesi kungahlola ama-molecule e-solute amancane kunosayizi wembotshana ukuze ahlukanise izinhlayiya ezinesisindo semolekyuli esikhulu kuno-500 Daltons (amayunithi obunzima be-athomu) kanye nosayizi wezinhlayiyana ezingaphezu kuka-10 nanometers.Ulwelwesi lwe-ultrafiltration lungenye yolwelwesi lokuqala lokuhlukanisa i-polymer olwakhiwe, futhi umshini wokuhlunga wenziwa imboni ngawo-1960.
2. Ubuhle nokubi kwe-ultrafiltration membrane kanye ne-reverse osmosis membrane:
Izinzuzo ze-ultrafiltration: ngokuvamile awekho amaphampu, awekho 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 ukwehlisa 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-membrane ye-fiber ultrafiltration engenalutho yokuhlanzwa okujulile kwamanzi, kufakazelwa ukuthi idivayisi yokuhlanza amanzi ye-ultrafiltration ingaqeda ngempumelelo ukungcoliswa kwesibili kwamanzi kunethiwekhi yamapayipi futhi ithuthukise ikhwalithi yamanzi.
Izinzuzo zemishini yokwelapha amanzi ehlanekezela i-osmosis: ikhwalithi yamanzi aphephile, ingasusa 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, izinkinga zokuphepha zikagesi;amalunga amaningi, umfutho wamanzi ophakeme, izinga eliphezulu lokuhluleka, kanye namathuba okuvuza kwamanzi;isakhiwo esiyinkimbinkimbi, kanye nenani elibiza kakhulu.
3. Uhla lokusetshenziswa lwe-ultrafiltration membrane kanye nolwelwesi lwe-osmosis oluhlehlayo:
Ububanzi bokusebenza be-reverse osmosis membrane
Ugesi, i-petrochemical, iron and steel, electronics, imithi, ukudla nesiphuzo, ukuphathwa kukamasipala nokuvikelwa kwemvelo kanye neminye imikhakha, ekukhishweni kukasawoti emanzini olwandle namanzi anosawoti, amanzi okuphakelayo okubhayela, amanzi ahlanzekile ezimbonini kanye nebanga le-elekthronikhi ukulungiswa kwamanzi ahlanzekile kakhulu, ukuphuza ukukhiqizwa kwamanzi ahlanzekile, ukwelashwa kwamanzi angcolile kanye Inqubo ekhethekile yokuhlukanisa 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. ukuhlukaniswa, ukugxilisa ingqondo nokucaciswa;Amanzi angcolile ezimbonini kanye nokuhlanzwa nokutholwa kwendle;Ukubuyiselwa kopende we-electrophoretic.
