What Is MBBR

The main characteristic of Moving Bed Biological Reactor (MBBR) configurations is that there is no sludge recycle from a secondary clarifier. MBBR is essentially a simple, once-through process, where all of the biological activity takes place on the biomass carriers. MBBR is usually followed by a solids separation system such as a secondary clarifier or DAF, in order to separate bio-solids produced in the process from the final effluent. The main advantage of MBBR is robust and simple reduction of soluble pollutants (soluble BOD or COD, NH4 +, etc.), with minimal process complexity, utilizing a significantly smaller footprint when compared to conventional aerobic treatment methods. MBBR is typically used for either high load industrial applications or for robust simple-to-operate municipal facilities.

MBBR Media Used in Wastewater Treatment

• Placing MBBR media into activated sludge basins creates a combination of suspended and attached growth biology that optimizes the benefits of both of these systems.

• Each individual piece of BioCell media has been specifically designed with a very high surface area-to-volume ratio to support the growth of biofilm.

• The surface area provided by the BioCell media creates additional active biology above and beyond the limits of the suspended activated sludge system.

How Does MBBR Work

Moving bed bioreactor (MBBR) includes a water tank of any shape filled with small carrier elements. These elements are specially developed materials with controlled density, so they can be fluidized using aeration equipment. Biofilms will form on the components, and these will move with the wastewater in the reactor. The movement in the reactor is generated by providing aeration in the diffuser located at the bottom of the reactor. The thin biofilm on the element enables bacteria to act on the biodegradable substances in the wastewater and reduce the BOD / COD content in the presence of oxygen in the air for fluidization. The treated water flows through the grid or sieve from the reactor, thereby retaining the MBBR biocarrier in the reactor. The system can be composed of a one-stage or two-stage treatment process according to the specific needs of wastewater.
