Biofilters

The air to be treated is filtered through porous organic material, also called filter material or biomass, which serves as a support and, in part, nourishment for aerobic microorganisms. The latter carry out a biochemical oxidation process on polluting organic compounds.

Unlike other deodorization treatments of a chemical or physical nature, biofiltration has the result of eliminating odorous pollution from the air and not transferring it to another location.
