Moving Bed Bioreactor (MBBR)

The Moving Bed Biofilm Reactor (MBBR) grows bacteria on plastic media. This is also known as “Attached Growth.” The system consists of a tank that is aerated, in which the plastic media is mixed. This plastic media enhances the biofilm’s contact surface area, effectively reducing the footprint of the aeration system. The attached growth makes the system resilient to load fluctuations, because of which these systems are often used in industrial applications where significant variability can be expected. Post treatment, the sludge is settled out and removed from the system, and the water is easily treated to remove any suspended particles.
