ABSTRACT:
A porous biomass support system in a fixed bed reactor configuration affords biodegradation of phenolic materials to a level under 20 parts per billion at an hydraulic residence time of about 15 hours with significantly less sludge formation currently possible by available methods. The porous biomass support system utilizes an open-celled foam within which is entrapped small particles of porous activated carbon and suitable microorganisms. The carbon is self-regenerative and does not have to be periodically replaced or replenished. The entire porous biomass support system can operate for extended periods of time without replacement.
