Polluted Air Treatment

Biofiltration is one of the universal methods for efficient treatment of polluted air containing compounds such as hydrogen sulphide, ammonia, sulfur dioxide, amines, phenol, formaldehyde, formalin, and nitric acid. Biofilters use biological processes to remove air pollutants that are toxic, of environmental concern and/or have an unpleasant odour.  Osorno’s BioScrub™  (often called BioDigestor®) with BioAer® aeration floor is the most advanced system offered world-wide, with unsurpassed performance, reliability and availability.
