Moving Bed Biological Reactor

MBBR processes are an excellent solution for common wastewater applications including BOD Reduction, Nitrification, and Total Nitrogen Removal. They are based on biofilm principle and utilize the advantages of activated sludge. The core of the process is the biofilm carrier elements which are made from polyethylene with a density slightly below water carrier elements are formed in such a way that it gives a large protected surface for the biofilm and optimal conditions for the bacteria culture when the elements are circulated in the water. The reactor is normally filled up to 67% of the water volume with carrier elements.

MBBR process configurations usually require wastewater pretreatment with influent screening, grit removal and primary treatment or fine mesh influent screening and grit removal. Chemical addition to the primary clarification step is also an option for chemically enhanced primary treatment to reduce the BOD load to the MBBR process or as a first step for phosphorous removal.

MBBR is considered the economical solution for wastewater treatment in the industrial and municipal markets. MBBR processes are economically attractive, compact (small footprint), maintenance friendly, simple to extend, have low solid generation, low or no polymers are required for liquid/solid separation and are easy to operate.
