Anaerobic Membrane Bioreactors (AnMBRs) for Wastewater Treatment: Recovery of Nutrients and Energy, and Management of Fouling

Anaerobic membrane bioreactor (AnMBR) technology is emerging as an alternative to conventional anaerobic treatment due its complete biomass retention, short start-up time, high effluent quality, and small footprint. This paper provides a general overview of the application AnMBRs for industrial municipal wastewater treatment. The potential benefits are discussed, such degradation organic matter energy production, concentration nutrients subsequent reclamation, or effective removal contaminants water reuse. To explore energy-neutral treatment, recovery methane, hydrogen, ethanol summarized, highlighting problems dissolution methane in permeate competition between sulfate-reducing bacteria methanogens matter. Recovery reuse, e.g., algae reported. Since fouling remains challenge operation leads increased maintenance costs, methods reduce highlighted. Future research prospects related AnMBR resource plants management emphasized.
