|MOVING BED BIOFILM REACTOR (MBBR)|
|Overview||Moving bed biofilm reactor (MBBR) is a type of wastewater treatment process that was first invented by Prof. Hallvard Ødegaard at Norwegian University of Science and Technology in the late 1980s. It was commercialized by Kaldnes Miljöteknologi (now called AnoxKaldnes and owned by Veolia Water Technologies). There are over 700 wastewater treatment systems(both municipal and industrial) installed in over 50 countries. Currently, there are various suppliers of MBBR systems.|
|How Does it Works||
The MBBR system consists of an activated sludge aeration system where the sludge is collected on recycled plastic carriers. These carriers have an internal large surface for optimal contact water, air and bacteria. The bacteria/activated sludge grow on the internal surface of the carriers. The bacteria break down the organic matter from the waste water. Aeration system keeps the carriers with activated sludge in motion. Only the extra amount of bacteria growth, the excess sludge will come separate from the carriers and will flow with the treated water towards the final separator.
The system can consist of a one stage or more stage system, depending on the specific demands. The specific bacteria remain in their own duty tank because of the fact that the carriers remain in only 1 tank, protected by screens.
