Conventional Biofiltration

The biofiltration with organic biomedia is a clean technology and highly efficient for the removing of odours and VOCs, that taking advanced of the microorganisms that the biomass contains allows to eliminate the different odours substances of an air stream.
Due to the characteristics of many of the compounds that causes bad odours, in many occasions these emissions do not admit just one treatment as unique and effective, however, the Biofiltration allows to treat mainly all those compounds in just one process. The process consists on putting the polluted air into contact with a fixed biomass bed, that, despite not being inoculated with specific microorganisms is capable of achieving depurating performance quite high, close to 70 %. In the case of organic conventional biofiltration, the free life microorganisms proliferate in a natural way over the organic material, using the odorous compounds as a nutrient and energy source, by means of aerobic decomposition.

The air depuration by means of biofilters is one of the more environmentally friendly strategies for the intensive odour removing pollutants, with the great advantage that it does not generate any waste, except for the biomedia (which can be treated as compostable organic waste once its half-life has expired).
