Isithambisi sedrama sisebenza ngenqubo yokuqina kwedrama ejikelezayo ukuze sithole umphumela wokwelashwa kokuqukethwe okuqinile okuphezulu.
Izindleko zomhlaba, zokwakha kanye nezabasebenzi ziyongiwa njengoba lo mshini uthatha indawo encane phansi ngesakhiwo sawo esilula, izidingo ezincane zokuntanta kanye nokusebenza okuzenzakalelayo ngokuphelele.

Ngenxa yalokho, i-slurry iyaqina. Amandla okucubungula i-rotary drum sludge thickener yethu ayathuthuka, futhi isikhathi sokusebenza siyafinyezwa. I-sludge ehlukanisiwe inganciphisa kakhulu umthwalo webhande lokungena emanzini. Okwamanje, iqembu le-sludge lakhiwe ngokuqinile. Akukho mcimbi wokugcwala kweshidi noma wokugcwala eceleni okuzokwenzeka. Ngemuva kwalokho, ukusebenza kahle kokuphelelwa amanzi emzimbeni kuyakhuliswa, futhi izinga lokuqukethwe kwamanzi liyehliswa. Ngemva kokuhlukaniswa, okuqukethwe okuqinile kwamanzi akhululekile kuyahlukahluka kusuka ku-0.5‰ kuya ku-1‰, okuhlobene eduze nomthamo kanye nezinhlobo ze-polymer.

Isithambisi-drum esijikelezayo esijikelezayo esingama-centrifugal singahlunga amanzi akhululekile ngamandla angaphandle. Sinezidingo eziphezulu ze-polymer kanye namandla okubopha e-sludge. Uma kuqhathaniswa nomshini wokuqinisa ibhande, isithambisi-drum sethu esijikelezayo se-sludge singanikeza i-sludge eqinisiwe enokuqukethwe kwamanzi okuphansi. I-sludge enokuqukethwe kwamanzi okungaphezu kuka-1.5% iyisinqumo esingcono.
