Inkcazo emfutshane:

Isixhobo sokuxubha idrama esijikelezayo esincinci singahluza amanzi akhululekileyo ngamandla angaphandle. Sineemfuno eziphezulu zepolymer kunye namandla okubopha i-sludge. Xa kuthelekiswa nomatshini wokuxubha ibhendi, isixhobo sethu sokuxubha idrama esijikelezayo sinokubonelela nge-sludge exineneyo enomthamo wamanzi ophantsi. I-sludge enomxholo wamanzi ongaphezulu kwe-1.5% lukhetho olungcono.
