Technical Note: Biotrickling Filters For Treating Emissions Of Odors And Volatile Organics Compounds (VOCs)

Biofiltration has been used to control odors and emission of volatile organics from industrial processes, wastewater treatment plants, solids handling operation and numerous other sources. Biofiltration involves the biological transformation by active bacteria of organics and odors into carbon dioxide and water. The fact that air contaminants can be biodegraded by active bacteria has been known for quite some time. However, it is only in the last 10 years that biofiltration has begun to emerge as an economically viable treatment process.
