Reduction of Perchlorate and Other Micropollutants in a Hydrogen-Based, Hollow-Fiber Membrane Biofilm Reactor

摘要

The membrane biofilm reactor (MBfR) a novel bioreactor that provides gaseous substrates directly to a biofilm growing on the membrane surface, avoiding the need for sparging. MBfRs are not membrane bioreactors (MBRs), where membranes separate suspended solids from the effluent water, substituting for a clarifier. In MBfRs, a gaseous substrate moves across the membrane. Since the MBfR membranes typically are microporous and hydrophobic, water and bacteria do not penetrate and block the pores. This paper describes H2-based MBfRs for removal of perchlorate and other oxidized micropollutants contaminants.
