Seminar Abstract 

This presentation will feature early results from testing of an anaerobic wastewater treatment system with the potential to transform the energy balance of wastewater treatment and water reuse. As the nation confronts increasing water scarcity challenges, the development of new sources of water including seawater, brackish water, and wastewater is becoming increasingly critical. Of these source waters, wastewater is the most energetically attractive for recovery, due to its relatively low salinity and proximity to water demand centers. Current wastewater treatment systems rely on aerobic technology that is energy-intensive, generates significant GHG emissions and produces large quantities of biosolids with high disposal costs.

The Staged Anaerobic Fluidized Bed Membrane Bioreactor (SAF-MBR) is an anaerobic secondary treatment system that converts organic matter into methane, reducing energy requirements, GHG emissions, and costs of biosolids transport and disposal. This presentation will discuss results from prior tests of the technology, compare these with other anaerobic membrane bioreactors, and provide initial results of ongoing testing at Stanford University’s Codiga Resource Recovery Center. The presentation will also discuss next stages of testing that are about to commence at Silicon Valley Clean Water thanks to support from the California Energy Commission.

Sebastien Tilmans
Director of Operations, Stanford University Codiga Resource Recovery Center

Sebastien is the director of operations at Stanford University'sWilliam and Cloy Codiga Resource Recovery Center. Prior to joining CR2C, he worked in the process engineering group at Oceanside wastewater treatment plant for the San Francisco Public Utilities Commission. An environmental engineer, he co-founded the resource urban household sanitation initiative prior to completing his PhD in Environmental Engineering at Stanford University in 2015. His dissertation focused on extracting value from the resources in organic wastes to improve the social, financial, and environmental outcomes of waste management services. Prior to his PhD, Sebastien spent three years in Panama designing and building energy-producing sanitation systems in rural communities with funds from USAID. He was a Fulbright Scholar, a National Defense Science and Engineering Graduate Fellow, and an EPA STAR Fellow. He earned his Bachelors Degree in Civil Engineering, Suma Cum Laude, at Cooper Union in New York City.
