Umgaqo osebenzayo wezihluzo zokuhlamba umva ziquka ikakhulu le miba ilandelayo:

Ukusebenza okuqhelekileyo kokucoca. Xa isihluzo sisebenza kakuhle, amanzi aqukuqela kwisihluzo kwaye asebenzise umthetho-siseko we-inertia ukufaka amasuntswana amancinci, ukungcola, kunye nezinto eziqinileyo ezimisiweyo emanzini kufuphi nendawo yokukhupha. Ngeli xesha, i-valve yokuguqula ukuhamba kwamanzi ihlala ivulekile ukuququzelela ukufakwa kokungcola.

Ukugungxulwa kunye nenkqubo yokukhutshwa kwamanzi amdaka. Xa ucoca isikrini sokucoca, ivalve yokuguqula ukuhamba kwamanzi ihlala ivulekile. Xa isixa sobumdaka esithatyathwe sisihluzo sifikelela kwinqanaba elithile, i-valve kwindawo yokukhupha ivuliwe, kwaye ukungcola okunamathele kwisihlunu kuyahlanjululwa ngokuhamba kwamanzi kude kube yilapho amanzi akhutshiweyo acacile. Emva kokugungxulwa, vala i-valve kwindawo yokukhupha kwaye inkqubo iya kubuyela ekusebenzeni okuqhelekileyo.

Ukuhlamba umva kunye nenkqubo yokukhutshwa kwamanzi amdaka. Ngexesha lokuhlamba umva, ivalve yokuphambuka kwamanzi ivaliwe kwaye ivalve yokukhupha amanzi iyavulwa. Oku kunyanzela ukuhamba kwamanzi ukuba angene kwicala elingaphandle lekhatriji yokucoca ngomngxunya okwindawo yokungena yekhatriji yokucoca, kunye nokubuyisela umva ukugungxula ukungcola okunamathela kumngxuma womnatha nge-interlayer yeqokobhe, ngaloo ndlela kufezekiswa injongo yokucoca Ikhatriji yokucoca. Ngenxa yokuvalwa kwevalve yokulawula, isantya sokuhamba kwamanzi sanda emva kokudlula kwi-valve ye-backwash, okukhokelela kwisiphumo esingcono sokubuyisela umva.

Isishwankathelo, i-backwash filter isusa ngokufanelekileyo ukungcola emanzini kwaye ikhusela ukusebenza okuqhelekileyo kwezinye izixhobo kwinkqubo ngokusebenzisa iindlela ezintathu: ukuhluzwa okuqhelekileyo, ukukhutshwa kwe-flushing, kunye nokukhutshwa kwe-backwashing.
