What is MBBR - Moving Bed Biofilm Reactor?
Moving bed biofilm reactor, or MBBR, is a version of an activated sludge system but is a much more compact method that can be scaled to fit any size plant. It is a biological treatment method.
How does MBBR work?
In this method, the reactor is filled with thousands of biofilm carriers (plastic balls) that protect the bacteria used to break down pollutants in the wastewater. A diffuser grid produces the air required to effectively disperse the biofilm carriers throughout the basin, while also providing the necessary aeration for biofilm growth.
There are four different elements within an MBBR system: aeration tank, media, aeration grid, and sieve.
- The wastewater treatment process occurs within the aeration tank.
- The media is thousands of small plastic chips that, given their density, are able to mix throughout the wastewater.
- The aeration grid is akin to a fan; it helps keep the media moving throughout the wastewater while introducing oxygen into the aeration tank.
- Finally, the sieve is the piece of equipment that prevents the media from leaving the aeration tank.
What are the benefits of MBBR?
The MBBR wastewater treatment method is certainly one of the most popular biological treatment methods, and for good reason. First - it's compact and has a smaller footprint as compared to other methods. It is a relatively straightforward process with fewer steps, has few maintenance requirements, and is also extremely efficient.

Additional Wastewater Treatment Applications
Membrane Bioreactors
Membrane bioreactors feature an ultrafine membrane filter installed at the discharge end of a standard aeration basin. Pumps installed on the membrane filters create a slight vacuum and pull the effluent through the membrane. The ultrafine holes in the membrane do not allow the biological microbes to pass through the membrane.
