A Study Performance Evaluation of Moving Bed Biofilm Reactor and its Modification

In recent years, an increasing interest in biofilm processes for the treatment of municipal and industrial wastewaters has been observed. One of the growing biofilm technologies is the Moving-bed Biofilm Reactor (MBBR), which has been successfully established in the market. A great number of large-scale wastewater treatment plants along with many other smaller treatment installations around the world make use of the MBBR concept. The development of the MBBR process was based on the central idea of obtaining, in a single system, the best characteristics of the activated sludge and biofilm processes. With the biomass immobilized on a free-support media, solids retention in the biological reactor is enhanced. This chapter covers the principle of the MBBR operation, the biofilm carriers employed in such systems, the key operational aspects and a broad range of applications of this technology.
