Due to its process-integrated biological degradation, the biofilter is an economically prices and efficient procedure for odour removal and the treatment of low concentrated or undefined air flows. This advantage lies in the natural decomposition of air pollutants into harmless products. Bio filters Let the microbes take care of the odorous waste air. The biological procedure processes complex organic compounds to harmless products such as CO2 and H2O.
Procedurally, the biofilter consists of an organic and damped packing. The air to be treated flows through the packing with minor velocity. The packing naturally contains a microflora that increases with convenient milieu conditions and adapts to the components which are to be removed.
When flowing through the organic biofilter bed, the contaminants are being absorbed by the filter material and dissolved in a thin liquid film which is around the filter material. The now dissolved contaminants enter the cells of the microoganisms by means of diffusion and osmosis and are decomposed into harmless products.
Biofilters are unbeatable in cleaning odorous or low concentrated exhaust air. We have more than 800 references in these areas. In addition to that, biofilters are also suitable for the removal of volatile organic compounds (VOC) where other methods would be profitless in economic and ecological terms.
