Electrochemical Membrane Bioreactors for Sustainable Wastewater Treatment: Principles and Challenges

Membrane bioreactor (MBR) is a reliable and promising technology for wastewater treatment and reclamation. Recently, the electrochemical process has been integrated into MBRs, which refers to as an electrochemical membrane bioreactor (EMBR). In this paper, fundamental information of EMBRs, including reactor design and construction materials, is critically reviewed. Comprehensive assessment regarding EMBR performances and their economic and environmental significances is presented based on the recent publications. The existing challenges and future research prospects of EMBRs towards practical applications are also discussed.
