Moving Bed Biofilm Reactor technology employs thousands ofpolyethylene biofilm carriers operating in mixed motion within anaerated wastewater treatment basin?Each individual biocarrier increases productivity by providingprotected surface area to support the growth of heterotrophic andautotrophic bacteria within its cellsThe protected area of the biofilm and apt conditions help in growingand thriving of the bacteria culture. An aeration grid is situated at the bottom of the reactor that suppliesoxygen to the biofilm. 

• The biofilm on the carriers break down the wastewater and the treated water comes out through a grid or sieve in which the biocarriers are retained
