Strategies to enhance micropollutant removal from wastewater by membrane bioreactors: Recent advances and future perspectives

Wancen Liu et al.

Summary: Several effective strategies have been applied to improve MBR performance for micropollutant removal, particularly by optimizing operational conditions, employing high-retention membranes, adding functional materials, and integrating effluent purification processes. Advanced oxidation processes (AOPs) and high-retention membranes can complement MBR to secure almost complete removal of micropollutants, but further research is needed to evaluate technical and economic feasibility for industrial MBR applications.
