Moving Bed Biofilm Reactor (MBBR): Sesebelisoa sena se sebelisa likaroloana tsa talc tse kentsoeng joalo ka sejari sa biofilm, 'me se sebelisa ketso ea phallo ea metsi ho boloka likaroloana tsa sejari 'meleng oa metsi, le ho senya lintho tsa tlhaho tsa likhoerekhoere. Thepa ea MBBR e na le litšobotsi tsa ho ikamahanya le maemo ho moroalo oa lintho tse phelang le boleng bo tsitsitseng ba mokelikeli, 'me e loketse kalafo ea metsi a litšila a lik'hemik'hale, metsi a litšila a lino, metsi a litšila a lijo, joalo-joalo.
Fixed-Bed Biofilm Reactor (IFAS): Thepa ena ke sesebelisoa se kopanyang biofilm le mekhoa ea sludge e kentsoeng, 'me lijari tse sebelisoang hangata li kenyelletsa liponche, kaolin, joalo-joalo. Thepa ea IFAS e na le litšobotsi tsa ho ikamahanya le maemo ho matla a likhoerekhoere tse phahameng le phello e tsitsitseng ea phekolo. , 'me e loketse ho hloekisa metsi a litšila libakeng tsa ho hloekisa likhoerekhoere le lirapeng tsa boikhathollo tsa indasteri.
