Bio Film MBBR Moving Bed Biofilm Reactor is a biological wastewater treatment process

When communities of microorganisms grow on surfaces, they are called biofilm. Microorganisms in a biofilm wastewater treatment process are more resilient to process disturbances compared to other types of biological treatment processes.  Thus, biofilm wastewater treatment technologies can be considerably more robust especially when compared to conventional technologies like activated sludge. The very first biofilm process, the trickling filter, was invented towards the end of the 19th century. The trickling filter can be reliable and stable but does suffer from one serious drawback; it easily becomes clogged and septic even under moderate loading conditions. In the conventional attached growth biological treatment processes, like trickling filter or RBC systems, the microorganisms are attached to a medium that is fixed in place and the wastewater being treated flows past the surfaces of the medium with their attached biological growth. By contrast, in a suspended growth biological wastewater treatment process, like the activated sludge process, the microorganisms that carry out the treatment are kept suspended in the mixed liquor in the aeration tank.
