MBBR Reactors for STP

The main characteristic of Moving Bed Biological Reactor (MBBR) configurations is that there is no sludge recycle from a secondary clarifier.

MBBR is a simple, once-through process reactor, where all of the biological activity takes place on the biomass carriers. MBBR is followed by a solids separation system called secondary clarifier or DAF, in order to separate bio-solids produced in the process from the final effluent.

The main advantage of this system is robust and simple reduction of soluble pollutants (soluble BOD or COD, NH4+ , etc.), with minimal process complexity, utilizing a significantly smaller footprint when compared to conventional aerobic treatment methods.


Our MBBR is typically used for either high load industrial applications or for robust simple-to-operate municipal facilities.
