A variation on the anaerobic dynamic membrane bioreactor (AnDMBR) approach called the recirculating AnDMBR (R-AnDMBR) was developed to evaluate its potential for mainstream anaerobic treatment of municipal wastewater (MWW) and was designed, built, and tested to evaluate its performance, energy balance, cost, and environmental impact. The objectives of this project were specifically to design and fabricate a prototype R-AnDMBR, using additive manufacturing strategies; to evaluate the performance of the R-AnDMBR using simulated and real wastewater, each for over 100-day operating periods; to conduct energy balance, life cycle cost, and life cycle environmental analyses; and to summarize technology adoption recommendations based on interviews with stakeholders in the MWW field.
