Abstract：Biofilm thickness control is crucial to the successful operation and management of membrane aerated biofilm reactor (MABR) process. There is the optimal biofilm thickness to achieve the best simultaneous removal of carbon, nitrogen and phosphorus. The research and development of MABR biofilm thickness control technology (including periodic scouring, continuous hydraulic shear, eukaryotic predation, and quorum quenching) in the past 20 years are reviewed in this article. Future research and development directions on MABR biofilm thickness control are explored to provide references for the high-quality development of MABR process towards the goals of improving water quality, saving energy and reducing carbon emission.
