Moving Bed Biofilm Reactor

MBBR - Moving Bed Biofilm Reactor

With the Moving bed Bioreactor (MBBR) an economically solution is offered for wastewater treatment if the "bulk" of the pollution load must be disposed of (as means of cost reduction) or if applicable discharge regulations are not as strict.
With this application we offer advanced wastewater treatment solutions for the industrial and municipal markets. These solutions significantly increase the capacity and efficiency of existing wastewater treatment plants, while minimizing the size of new plant deployments.
This method makes it possible to attain good efficiency results of disposal with low energy consumption. This process is used for the removal of organic substances, nitrification and denitrification.

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 carrier material used inside a MBBR system

The bacteria/activated sludge grow on the internal surface of the carriers. The bacteria break down the organic matter from the waste water. The 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 (see underneath schedule), 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.

The MBBR process can be used for a variety of different applications to attain the desired results, depending on the quality of the wastewater and the discharge regulations.
