I-Ultra-filtration (UF) iwuhlelo lokuhlukanisa ulwelwesi oluhlanza futhi luhlukanise izixazululo.I-anti-pollution PVDF ultrafiltration membrane isebenzisa i-polymer material polyvinylidene fluoride njengengxenye yefilimu eluhlaza, ulwelwesi lwe-PVDF ngokwalo lunamandla okumelana ne-oxidation, ngemva kokuguqulwa okukhethekile kwempahla futhi ine-hydrophilicity enhle, ohlelweni lwe-membrane ngokusebenzisa i-micropore design yesayensi nokulawulwa kwesakhiwo se-micropore, i-micropore. usayizi we-pore ufinyelela izinga lokuhlunga.Lolu hlobo lwemikhiqizo ye-membrane inezinzuzo zama-pores afanayo, ukunemba okuphezulu kokuhlunga, ukungena kwamanzi okuphezulu endaweni ngayinye yeyunithi, ukumelana ne-oxidation namandla aphezulu okudonsa.
