As a collaborative effort between MWH and Northwestern University (NWU), the objective of
this research was to evaluate and optimize an innovative process called the membrane biofilm reactor (MBfR) to treat inorganic
and organic oxidized contaminants. During initial testing, it was discovered that a bench-scale
MBfR was effective in reducing 50 to 1000 µg/L perchlorate to below the previous California
Department of Public Health Services Advisory Action Level of 18-µg/L. At pilot-scale, the
objective was to evaluate the application of a pilot-scale MBfR system to biologically reduce
low-concentration perchlorate-contaminated water from an active groundwater well to below the
previous 4 µg/L CaDHS Action Limit. Fundamental bench-scale experiments were also
performed to systematically evaluate the potential of the MBfR to remove a variety of oxidized inorganic and organic compounds (including chromium, selenium, chloroform, trichloroethene,
and trichloroethane), and understand the micro-ecology behind these systems. Includes tables, figures.
