Abstract: Anaerobic biotechnologies such as anaerobic membrane bioreactors (AnMBRs) are emerging as one option to recover energy during domestic wastewater treatment. AnMBR generates methane-rich biogas, a renewable energy source, directly from wastewater while eliminating energy requirements for aeration and reducing sludge handling. However, AnMBR technology is still in development (e.g., bench- and pilot-scale systems to date for domestic wastewater applications) and widespread implementation requires (1) increasing energy recovery, (2) minimizing membrane fouling control energy demand, and (3) preventing greenhouse gas emissions from effluent dissolved methane. Systems-level thinking is one strategy to help elucidate design and operational goals for AnMBR development and guide future experimental research. This presentation will demonstrate how life cycle assessment can be applied to AnMBR and how these efforts can guide experimental research efforts. Ongoing research by the Smith Research Group will be presented focusing on improving energy recovery by integrating domestic wastewater and food waste management, reducing energy demands via novel membrane materials and fouling control mechanisms, and mitigating greenhouse gas emissions by methane-driven microbial fuel cells.
