Biofiltration is a process by which VOC and odorous compounds are degraded within the biofilter. When pollutants contact the biofilter media, they transfer from the air phase to the water phase which is a thin biological film surrounding each media particle. The bacteria within the biofilm, biologically oxidize the VOC and odorous compounds, converting them to carbon dioxide and water.

PPC Biofilter provides a pretreatment biofiltration system to condition the gas stream for optimum performance. The biofiltration pretreatment system includes temperature conditioning, humidification and particulate removal. The gas stream then flows into a fixed film biofilter reactor where the phase transfer and biological oxidation takes place.

The biofiltration system is designed to protect the biofilter media from the elements (rain, snow, wind, sun) and to provide a controlled (moisture control) within the biofilter reactor. The biofiltration system is designed to achieve maximum performance.
