MBBR (MOVING BED BIOFILM REACTOR)

It is a state-of-the-art fixed film (or attached growth) biological process used for wastewater treatment both municipally and industrially for BOD removal, nitrification and denitrification.

The MBBR system is considered a biofilm process. Biofilm processes in general require less space than activated sludge systems because the biomass is more concentrated, and the efficiency of the system is less dependent on the final sludge separation.

The MBBR system is often installed as an retrofit of existing activated sludge tanks to increase the capacity of the existing system. The degree of filling of carriers can be adapted to the specific situation and the desired capacity. Thus an existing treatment plant can increase its capacity without increasing the footprint by constructing new tanks.
