Moving Bed Membrane Bioreactor (MBBR)

Moving Bed Bio Reactor (MBBR) technology is an advancement over the conventional activated sludge technology and is a biological process of attached growth type. MBBR technology is an activated sludge treatment process where plastic media is used for the growth of bacteria. The plastic media is mixed in the tank by the aeration system which maintains effective contact between the organic matter in the wastewater and the microbial mass on the media. By using this media, large surface area is provided for the bacterial growth which reduces the foot print of the aeration system. The media is made of a material with a density close to the density of water.

Advantages of MBBR:

• MBBR is more resistant to shock load as compared to the conventional biological system.
• Lower foot print area over conventional aeration system.
• The process does not necessitate recirculation and hence power consumption is lower.
• The sludge retention time (SRT) in MBBR is higher which is favorable for the reduction of Ammonical nitrogen.
• MBBR process results in lower sludge production as compared to the conventional biological system.
