Biotrickling filter combines the advantages of biofilter and bioscrubber processes for purifying waste gas
Waste gas flows through a biomedia filter bed. An automatically controlled spraying nozzles system is installed above the biomedia filter bed in order to spray water with nutrients and mineral water onto the filter bed.
Therefore material must be capable to endure permanent contact with high and low pH gases and scrubbing solutions. Material range: PE, PP, PVDF, PVC as well as FRP in a composite construction. Processes based on physical -chemical oxidation are possible.
