Izinto ezikhethekile kanye nesakhiwo sesihlungi se-ceramic yekhekhe lezinyosi sinquma izici zayo. Okokuqala, inamandla amahle, ukumelana nokugqoka nokugqwala, nempilo ende yesevisi. Ngesikhathi esifanayo, ngenxa yamandla ayo amahle, akukho deformation of micropores, futhi ezinzile izinkomba zobuchwepheshe ngaphandle kokushintshashintsha; Ama-pores mancane (cishe ama-microns angu-1.5), isenzo se-capillary sinamandla, futhi i-filtrate ingena ngokuzenzakalelayo kuma-micropores. Umsebenzi wepompo ye-vacuum ukukhipha i-filtrate ukuze wonge amandla; (kufika ku-0.098Mpa) umswakama wekhekhe lokuhlunga uphansi, futhi i-coefficient yokusetshenziswa kwesihlungi iphezulu; futhi ngenxa yama-pores amancane, okuqukethwe okuqinile okumisiwe ku-filtrate kuphansi, futhi i-filtrate icacile, engasetshenziselwa ukujikeleza kwamanzi esizeni ukuvimbela ukungcoliswa kwemvelo nokulondoloza imithombo yamanzi.
