The membrane-aerated biofilm reactor (MABR) is a technology that can deliver oxygen at high rates and transfer efficiencies, thereby enhancing the biofilm activity. This paper provides a comparative performance rate analysis of the MABR in terms of its application for carbonaceous pollutant removal, nitrification/denitrification and xenobiotic biotreatment. We also describe the mechanisms influencing process performance in the MABR and the inter-relationships between these factors. The challenges involved in scaling-up the process are discussed with recommendations for prioritization of research needs.525818 bytesapplication/pdfenThis document is the Accepted Manuscript version of a Published Work that appeared in final form in Environmental Science and Technology, 42 (6): 1833-1844, copyright © American Chemical Society after peer review and technical editing by the publisher.
