This chapter overviews current studies on development and application of four types of enhancers in anaerobic membrane bioreactor (AnMBR) as hybrid AnMBR system during wastewater treatment. Chemical enhancers (e.g., electroassisted membranes, ozonation) induce high nitrogen and organic removal, biogas production, and energy recovery. Biocarrier enhancers (e.g., powdered activated carbon, zeolite) improve removal of various types of pollutants and energy recovery. Microbial enhancers (e.g., entrapped biomass technology, functional bacterium) accomplish effective removal of pollutants, realize high methane production, and encourage enrichment of functional microbial communities and presence of new emerging bacteria to resist extreme conditions. Membrane fouling control enhancers (e.g., electric field, quorum quenching technology) change sludge properties and inhibit the deposition of sludge flocs on membrane surface. Development of new flocculants, new carriers, and novel electrically conductive membranes, and application of quorum quenching technology in hybrid AnMBR systems are suggested to be future research direction.
