Advance Moving Bed Bio Reactor Process (A.MBBR)

A.MBBR carriers based aerobic biological wastewater treatment solutions are offered as IFAS (Integrated Fixed Film Activated Sludge) process configuration. However, over the past few decades, A.MBBR process is gaining momentum due to its hybrid configuration and specific benefits the process provides to the wastewater treatment plants. A.MBBR process with textile sheets, cord media and other fixed in place media has been around the scene quite for a long time and has been successfully applied for the up-gradation of existing overloaded activated sludge plants.

Though originally developed for the up-gradation of existing activated sludge plants, the hybrid process configuration can be applied for the new plants as well.


A.MBBR process is nothing but an activated sludge process with attached growth media added to the aeration basin.  Thus, in this process configuration, MLSS is also kept in the suspended phase along with A.MBBR carriers using RAS (Returned Activated Sludge) as practiced in the conventional activated sludge process. This combination of both suspended growth and attached growth process makes A.MBBR a truly hybrid process bringing advantages of both attached growth and suspended growth processes. This addition of attached growth media in different forms enhances the efficiency of the aeration tank by providing additional biomass in the aeration tank.


Advantages of A.MBBR as per its properties


Higher Specific Gravity Easier mixing and fluidization with lower energy requirement
Hydrophilic Surface Quicker colonization and biofilm formation, Better wetting and fluidization of media, and Lower energy consumption for mixing
Fine pores and higher porosity Faster colonization, Protection against shock loads, Better diffusion gradients and Development of specific biomass
Surface Roughness and adsorbing capacity Faster colonization
Lower degree of filling Better mixing, Better mass transfer and Better fluidization.
