I-Ultra-filtration (UF) yindlela yokwahlula inwebu ecoca kwaye yahlule izisombululo.I-anti-pollution PVDF ultrafiltration membrane isebenzisa i-polymer material polyvinylidene fluoride njengeyona nto iphambili yefilimu ekrwada, inwebu ye-PVDF ngokwayo inokumelana ne-oxidation eyomeleleyo, emva kokuguqulwa kwezinto ezikhethekileyo kwaye ine-hydrophilicity enhle, kwinkqubo ye-membrane ngokusebenzisa uyilo lwe-micropore yesayensi kunye nolawulo lwesakhiwo se-micropore, i-micropore. Ubungakanani bepore bufikelela kwinqanaba lokucoca.Olu hlobo lweemveliso ze-membrane zineenzuzo ze-pores ezifanayo, ukuchaneka okuphezulu kokucoca, ukungena kwamanzi aphezulu kwindawo nganye yeyunithi, ukuxhathisa kwe-oxidation kunye namandla aphezulu.
