Moving bed biofilm reactor (MBBR) is a biological technology used for wastewater treatment process and it is widely used in sewage treatment plants and aquaculture farms.
The technology is activated sludge process where the media is suspended in the reactor offers additional surface area for the microbes to grow and thus in turn maximizes the growth of microbes in a given volume of aeration tank.
The sludge is collected on the plastic media carriers and forms a biofilm which have a large surface area for the growth of microorganism.
MBBR (moving bed biofilm reactor) systems are active biofilm carriers with optimal bacteria culture conditions for wastewater treatment.
MBBR is compact, simple to operate and very efficient for reducing biochemical oxygen demand (BOD),chemical oxygen demand (COD), ammonia and nitrogen from the waste water.
The media creates an environment for effective nitrification to take place and it remains suspended in aeration tank which assist the media with bacterial growth.
Air is injected into the system and Water flow is created by aeration that circulates the media throughout the vessel/tank.
The process consists of adding small cylindrical shaped polyethylene carrier rings (MBBR media) with specific density of about 0.96 kg/m3 in aeration tanks to support the biofilm growth. The bio-media can be loaded at the rate of 15% – 65% of the total volume of aeration tank, depending on the BOD/COD load.
