Biofiltration
Due to its process-integrated biological regeneration the biofilter technique is an effective method for odor
elimination and treatment of low concentration or undefined exhaust air streams. This advantage is
realised due to the natural reactions of the biological degradation of contaminants. It takes place at:
ambient temperature
neutral pH and normal pressure
produced no problematic final products

Tholander Environmental Engineering has been founded in 1986. It has developed air pollution
control equipment and is one of the leading suppliers of odour control systems for industrial and
municipal applications.

The biotrickling filter is a 1-stage packed scrubber passed by the waste air from the bottom to the top. This
unit operates under limited aerobic conditions and uses specific bacteria to convert hydrogen sulphide into
water-soluble harmless components.
