Fixed biofilter in concrete
Biofiltration is a technique that eliminates contaminants in the air by means of micro-biotic oxidation.
The contaminated air flows pass through a matrix (biomass), in which there are the micro-organisms capable of degrading the pollutants by using them as a source of nourishment.
Biofilters are used to eliminate a wide variety of organic pollutants often characterised by their intense and unpleasant odour.
