Biofiltration is a process by which VOC and odorous compounds are degraded within the biofilter and the pre-treatment humidification system. When pollutants contact the biofilter media, they transfer from the air phase to the water phase. In the biofilter section, this 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 pre-treatment biofiltration system to condition the gas stream for optimum performance. The biofiltration pretreatment system includes temperature conditioning, humidification and particulate removal. Phase transfer and biological oxidation occur in both the pre-treatment and in the fixed film reactor.
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 meet the customers objective for state, EPA, and MACT Compliance.
