Moving Bed Biofilm Reactor (MBBR)

Moving Bed Biofilm Reactor (MBBR)

Moving bed biofilm reactor (MBBR) is a type of popular used Bio Media for wastewater treatment process.

Moving Bed Biofilm Reactor (MBBR)

The MBBR system consists of an aeration tank with special plastic carriers that provide a surface where a biofilm can grow. The carriers are made of a material with a density close to the density of water (1 g/cm3). An example is high-density polyetylene (HDPE) which has a density close to 0.95 g/cm3. The carriers will be mixed in the tank by the aeration system and thus will have good contact between the substrate in the influent wastewater and the biomass on the carriers






















Moving-Bed Bioreactor (MBBR) utilize attached growth media as a substrate for the formation of treatment biofilms. This media is circulated in aerated treatment reactors ensuring excellent oxygen and substrate transfer to the biomass. MBBR reactors are ideal for both aerobic and anoxic processes and are utilized with mechanical mixers for circulation in anoxic reactors for efficient nitrogen removal.

MBBR bio filter media provide not only large surface area for biofilm formation but also electrostatic surface charge. Charged surfaces on the media are biologically regenerated as ammonium ions which are adsorbed and then subsequently nitrified by the biofilm and desorbed. These reactive surfaces increase treatment efficiency and buffer the biofilm communities against toxic compounds in the wastewater.
