Membrane Aerated Biofilm Reactor (MABR)

Supplementing the biological treatment capacity of existing activated sludge process

Membrane Aerated Biofilm Reactor is a unique attached growth biofilm (fixed film) aeration system that greatly increases energy efficiency and capacity of wastewater treatment plants (WWTPs).

In WWTPs, aeration is used to deliver oxygen to bacteria that breakdown pollutants in wastewater.The conventional method of adding oxygen by pumping air and diffusing it as air bubbles is very energy-intensive. Instead, MABR uses a gas permeable membrane to transfer oxygen directly to the microorganisms. Through this system, energy savings of 75% are observed. MABR can be deployed in a matter of days to supplement the biological treatment capacity of an existing Activated Sludge process. After implementation, a plant can increase its treatment capacity by 50%, allowing for either higher treatment capacity or higher effluent quality. The modules can be retrofitted within a WWTP of almost any size.
