Ulwelwesi lwe-PVC luwulwelwesi olunomsebenzi wokuhlanza amanzi. Ingakwazi ukususa ngempumelelo ukungcola nokungcola emanzini, okuhlanganisa okuqinile okumisiwe, i-macromolecular organic matter kanye nama-ion athile, ngokuhlolwa ngokomzimba nokuhlolwa kwamangqamuzana, ngaleyo ndlela kuthuthukise ikhwalithi yamanzi. Ikhono layo lokuhlola lincike kusayizi nokuma kwe-membrane pores. Njengoba i-ultrafiltration membrane eyenziwe nge-PVC ine-membrane pores ecolekile, ingasusa izinhlayiya ezincane nezinto eziphilayo.
Ngaphezu kwalokho, ulwelwesi lwe-PVC lubuye lukwazi ukumelana namakhemikhali futhi aluguguleki kalula ngamakhemikhali anjengama-asidi, ama-alkali, nosawoti, okwenza luvumelane nezimo lapho kwelapha amanzi aqukethe izinto zamakhemikhali. Ngesikhathi esifanayo, ubuso be-membrane ye-PVC bushelelezi futhi abunamatheli kalula ekungcoleni, ngakho-ke kulula ukuhlanza nokugcina, futhi kungagcina ukusebenza kahle kokuhlunga kwamanzi.
Kodwa-ke, impahla ye-PVC ngokwayo ingase ibe nephunga, elingase lithinte ukunambitheka kwamanzi ahlungiwe ngawo. Ukuze kuxazululwe le nkinga, ikhabhoni ecushiwe ngokuvamile iyengezwa ngemuva kwefilimu ye-PVC ukuze imunce iphunga futhi ithuthukise ukunambitheka. Ikhabhoni ecushiwe inamandla okukhangisa aqinile futhi ingamunca ngempumelelo ukungcola kwemvelo emanzini futhi isuse izinsimbi ezisindayo, i-chlorine esele, inhlanganisela yezinto eziphilayo ezishintshashintshayo nokunye ukungcola.
Ngokuvamile, ulwelwesi lwe-PVC lunamathemba okusebenza abanzi emkhakheni wokuhlanza amanzi. Kodwa-ke, uma kucatshangelwa izinkinga zephunga engase ilethe, ezinye izinto noma ubuchwepheshe kungase kudingeke ukuthi kusetshenziswe ezinhlelweni zangempela ukuze kuthuthukiswe umphumela wokuhlanza amanzi.
