The odour-free alternative


The odour-free alternative

Due to its process-integrated biological degradation, the biofilter is an incomparably cheap 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.


Incomparaply cheap technique

  • Simple process technology
  • Operation through permanent staff of the operator
  • Advantage through the natural reaction conditions of the catabolism
  • Flexible concept

Reduced operating costs regarding

  • Energy consumption
  • Water consumption and effluent water
  • Use of chemicals
  • Maintenance efforts

Long-lasting construction

  • Plant components of corrosion resistent and chemical resistant materials

Biologically active filter material

  • High inner surface for the settlement of microorganisms
  • Steady perfusion
  • Good drainage impact

Integrated pre-scrubber

  • Dampening of the air until saturation
  • Stripping of pollutants through the microflora for an optimal operation
  • Dosing of various chemicals possible (multi-stage scrubber)

30 years of experience

  • Active references of each size
  • Worldwide delivery, installation and service


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.
