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.

Moving Bed Biofilm Reactor (MBBR) processes improve reliability, simplify operation, and require less space than traditional wastewater treatment systems.
MBBR (Moving Bed Biofilm Reactor) Filter Media is one of the best media for breaking down ammonia and nitrite. Great for use in DIY aquarium or pond filters. It works most efficiently in a fluidized application where an air pump is used to fluidize the media. A biofilm will develop on the surface of the media and start to break down ammonia & nitrite. In a fluidized filter, the media is self-cleaning and never needs to be replaced. As the media tumble inside the filter chamber and are bumping into each other constantly, detritus and dead bacteria are knocked off and never needs cleaning. MBBR Media is also a great alternative to bioballs in a wet/dry filter.
A good MBBR carrier has the following characteristics:
• A large protected surface area to maximize the amount of biomass;
• A porous surface to strengthen the biomass's adhesion;
• An optimal substrate diffusion depth to ensure the metabolism;
• Wear-resistance for durability.
