METHOD FOR BIOLOGICAL TREATMENT OF AN AIR STREAM CONTAINING VOCS

摘要

A method of operating a facility that produces an emission air stream containing gas phase organic compounds includes providing a bio-oxidation system including a solid, biologically active filter material containing a population of thermophilic microbes. The emission air stream is supplied to the bio-oxidation system at a temperature of at least about 50C, whereby the emission air stream passes through the bio-oxidation system in contact with the biologically active filter material. Conditions conducive to sustaining the population of thermophilic microbes in the biologically active filter material are maintained in the bio-oxidation system.
