Degradation of trichloroethylene and trans-1,2-dichloroethylene by a methanotrophic consortium in a fixed-film, packed-bed bioreactor

An illustrated description is given of a fixed-film, packed-bed bioreactor containing micro-organisms capable of utilizing methane as a primary source of carbon, and results are presented from experiments using this equipment to treat a synthetic groundwater contaminated with trichloroethylene (TCE)...

Description
Summary:An illustrated description is given of a fixed-film, packed-bed bioreactor containing micro-organisms capable of utilizing methane as a primary source of carbon, and results are presented from experiments using this equipment to treat a synthetic groundwater contaminated with trichloroethylene (TCE) and trans-1,2-dichloroethylene (DEC). With influent concentrations of 1 mg per litre for each chemical, and a retention period of about 50 minutes, over 50 per cent of TCE and over 90 per cent of DCE were degraded in a single pass through the reactor, and further degradation of TCE could be achieved with recirculation of effluents.
