Biological MMBR /UASB

Aerobic and Anaerobic Wastewater Treatment

Biological MBBR is a highly effective biological treatment process used in the industry based on a combination of conventional activated sludge and biofilm media. The MBBR process utilizes floating High-capacity Microorganism media within the aeration and anoxic tanks. The microorganisms consume organic material.



The media provides increased surface area for the biological microorganisms to attach and grow. The increased surface area reduces the footprint of the tanks required to treat the wastewater. The treatment process can be aerobic or anaerobic and operates at high volume loads.


UASB uses an anaerobic process whilst forming a blanket of granular sludge, which suspends in the tank. Wastewater flows upwards through the blanket and is processed (degraded) by the anaerobic microorganisms. The upward flow combined with the settling action of gravity suspends the blanket with the aid of flocculants.
