Umgomo wokusebenza wezihlungi ze-backwash ikakhulukazi uhlanganisa izici ezilandelayo:

Umsebenzi wokuhlunga ojwayelekile. Uma isihlungi sisebenza kahle, amanzi ageleza kusihlungi futhi asebenzise isimiso sokungaguquki ukuze afake izinhlayiya ezincane, ukungcola, nezinto eziqinile ezimisiwe emanzini eduze nendawo yokukhipha. Kuleli qophelo, i-valve yokuphambukisa amanzi ihlala ivulekile ukuze kube lula ukufakwa kokungcola.

Inqubo yokukhishwa kwe-flushing ne-sewage discharge. Lapho uhlanza isikrini sokuhlunga, ivalve yokuphambukisa amanzi ihlala ivuliwe. Lapho inani lokungcola elibanjwe isihlungi lifinyelela izinga elithile, i-valve endaweni yokukhipha ivuliwe, futhi ukungcola okunamathele kusihlungi kugezwa ukugeleza kwamanzi kuze kube yilapho amanzi akhishiwe ecacile. Ngemuva kokugeza, vala i-valve endaweni yokukhipha amanzi futhi uhlelo luzobuyela ekusebenzeni okujwayelekile.

Ukugeza emuva kanye nenqubo yokukhipha indle. Ngesikhathi sokugeza emuva, i-valve yokuphambukisa amanzi ivaliwe futhi i-valve yokudonsa iyavulwa. Lokhu kuphoqa ukugeleza kwamanzi ukuthi kungene ohlangothini olungaphandle lwekhatriji yesihlungi ngembobo enezikhala engxenyeni yokungena yekhathriji yesihlungi, nokubuyisela emuva ukungcola okunamathela embotsheni enezikhala nge-interlayer yegobolondo, ngaleyo ndlela kufezwe injongo yokuhlanza i-cartridge yokuhlunga. Ngenxa yokuvalwa kwe-valve yokuqondisa, izinga lokugeleza kwamanzi liyakhula ngemva kokudlula ku-valve ye-backwash, okuholela kumphumela ongcono wokubuyisela emuva.

Kafushane, isihlungi se-backwash sisusa ngokuphumelelayo ukungcola emanzini futhi sivikela ukusebenza okuvamile kwezinye izinto zokusebenza ohlelweni ngokusebenzisa izindlela ezintathu: ukuhlunga okuvamile, ukukhishwa kwe-flushing, nokukhishwa kwe-backwashing.
