This project evaluated the feasibility and applicability of high-rate anaerobic treatment for municipal wastewater. The scope included laboratory and pilot analysis to understand process limitations, solids and gas (methane) separation techniques, and design considerations for this technology at wastewater treatment facilities in the United States.

The research team used acoustic Doppler meters to record actual velocity measurements within an active digester. These data allow for the first-ever profile of the measured velocities within an active anaerobic digester. This protocol provides valuable information needed to design and to optimize the efficacy and biogas production of anaerobic digesters. Published in 2019.
