A Moving Bed Batch Reactor (MBBR) is a type of batch reactor designed to enhance the efficiency of chemical and biological reactions. It’s characterized by the use of a moving bed of media that supports the growth of microorganisms or catalysts.

MBBR mainly is combined of two things i.e. Activated sludge process (suspended growth) and biofilter (attached growth). It uses entire tanks for biomass growth through implementation of carriers that are attached to the biofilm.

Since MBBR uses activated sludge aeration tanks, the sludge gets collected on the plastic carriers. These carriers contain a large surface area benefit of which is that it optimizes the contact of water, air, and the bacteria. The above two systems are an essential application of MBBR media. MBBR media contains two features, one is the aeration tanks and the other is special plastic carriers.
