Membrane　bioreactor　(MBR)　has　been　widely　implemented　to　advance　wastewater　treatment　and　reuse.　Nevertheless,　conventional　MBRs　with　porous　microfiltration　or　ultrafiltration　membranes　are　not　designed　for　the　removal　of　micropollutants,　which　ubiquitously　occur　in　wastewater　at　trace　concentrations,　but　potentially　exert　detrimental　impacts　to　the　ecosystem.　Several　effective　strategies　have　been　applied　to　improve　MBR　performance　for　micropollutant　removal,　particularly　the　hydrophilic　and　recalcitrant　compounds.　These　strategies　mainly　include　the　optimization　of　operational　conditions,　employment　of　high-retention　membranes　to　replace　porous　ones,　addition　of　functional　materials　into　bioreactor,　and　integration　of　effluent　purification　processes.　In　particular,　effluent　purification　by　advanced　oxidation　processes　(AOPs)　and　high-retention　membranes　can　complement　MBR　to　secure　almost　complete　removal　of　micropollutants.　Nevertheless,　further　research　is　still　necessary　to　evaluate　the　technical　and　economic　feasibility　of　these　strategies,　especially　for　long-term　treatment　performance,　to　screen　the　suitable　techniques　for　industrial　MBR　applications.
