PVC nembanemba ndi nembanemba zinthu ndi ntchito kuyeretsa madzi. Imatha kuchotsa bwino zonyansa ndi zowononga m'madzi, kuphatikiza zolimba zoyimitsidwa, ma macromolecular organic matter ndi ma ion, poyang'ana thupi ndikuwunika mamolekyulu, potero kuwongolera madzi. Kukhoza kwake kuwunika kumadalira kukula ndi mawonekedwe a nembanemba pores. Popeza nembanemba ya ultrafiltration yopangidwa ndi PVC ili ndi ma pores owoneka bwino, imatha kuchotsa tinthu ting'onoting'ono ndi zinthu zachilengedwe.
Kuphatikiza apo, nembanemba ya PVC imakhalanso ndi kukana bwino kwamankhwala ndipo sikukokoloka mosavuta ndi mankhwala monga ma acid, alkalis, ndi mchere, zomwe zimapangitsa kuti zizitha kusintha kwambiri pochiza madzi omwe ali ndi mankhwala. Panthawi imodzimodziyo, pamwamba pa PVC nembanemba ndi yosalala ndipo sichimamatira kudothi mosavuta, choncho n'zosavuta kuyeretsa ndi kusunga, ndipo imatha kusunga kusefera kwamadzi.
Komabe, zinthu za PVC zokha zimatha kukhala ndi fungo, zomwe zingakhudze kukoma kwa madzi osefedwa. Kuti athetse vutoli, kaboni woyendetsedwa nthawi zambiri amawonjezedwa kuseri kwa filimu ya PVC kuti atenge fungo ndikuwonjezera kukoma. Mpweya wopangidwa ndi activated uli ndi mphamvu yamphamvu ya adsorption ndipo umatha kuyamwa bwino zowononga organic m'madzi ndikuchotsa zitsulo zolemera, klorini yotsalira, ma organic compounds osakhazikika ndi zoipitsa zina.
Nthawi zambiri, ma membrane a PVC ali ndi mwayi wogwiritsa ntchito kwambiri pakuyeretsa madzi. Komabe, poganizira zovuta za fungo zomwe zingabweretse, zida zina kapena matekinoloje angafunike kugwiritsidwa ntchito ngati zenizeni kuti apititse patsogolo kuyeretsa madzi.
