Biofiltration is a universal method for efficiently treating air that is polluted with compounds such as hydrogen sulphide, ammonia, sulfur dioxide, amines, phenol, formaldehyde, formalin, and nitric acid. Biofilters contain substrates populated by living micro-organisms that will digest biodegradable pollutants called biosubstrates. Biosubstrates remove air pollutants that are toxic, are of environmental concern, or have an unpleasant odour.
Biofiltration has certain advantages over conventional scrubbers or adsorbers.
Biosubstrates are constantly operating and the transfer zone is stationary and relatively short. Biofilters are not required to regenerate and filter bed sizes are sufficiently small. Biofilters destroy contaminants while conventional filters adsorb them.
These features show that biofilters are more economical than conventional filters.
Osorno's BioScrub™ (also called BioDigestor®) in conjunction with a BioAer® aeration floor is an excellent way to begin biofiltration with outstanding performance and reliability.
