Event Description:
Join us to learn about a promising pilot project that is looking at Staged Anaerobic Fluidized-bed Membrane Bioreactor (SAF-MBR), for secondary wastewater treatment.
The process is anaerobic, eliminating the necessity for aerators, which is typically the largest user of energy in the wastewater treatment process. Instead of relying on an aerobic process that would produce large amounts of biosolids during BOD removal, the anaerobic system converts most BOD to methane, producing 30-50% less biosolids than a conventional treatment system. Its estimated methane production will be double the amount normally produced at a conventional plant with digesters and aerobic secondary treatment. Increased biogas production coupled with lower energy consumption by eliminating aeration means the SAF-MBR could convert a wastewater treatment plant into a net renewable power exporter.
The four-year pilot study has an overall budget of $3.2 million, and is partially funded through a $2 million grant from the California Energy Commission, plus contributions from Stanford University, Silicon Valley Clean Water, Suez Water Technologies (formerly GE Water), Santa Clara Valley Water District, and LG NanoH20.

Craig Criddle, Professor of Civil and Environmental Engineering at Stanford University
Sebastien Tilmans, Executive Director of the Codiga Resource Recovery Center at Stanford University
Teresa Herrera, General Manager of Silicon Valley Clean Water
