Tech Sheet: Biocatalytic Treatment Of Odors
Biofiltration has been shown to be an effective technology for odor control and has been successfully applied in many industrial and municipal installations. Biofiltration is generally conducted using either naturally bioactive support media, such as peat, compost, soil, wood chips, etc., referred to as a "biofilter" or synthetic support media, known as a "biotrickling filter". Compost biofilters suffer from large cross-sectional areas, requiring very large footprints, shallow depths of compost (usually limited to about 1-2 m), gas by-passing, clogging of the compost due to biological growth, and eventual consumption of the available nitrogen and phosphorus in the compost media, requiring partial or total media replacement.
