Influence of Key Parameters on the Removal Efficiency of Air Pollutants by a Biotrickling Filter

Abstract

A chemical scrubber followed by a biotrickling filter (BTF) was integrated in the air treatment line of a composting plant, originally equipped with an open-bed biofilter. Such integration is motivated by the poor performance of the biofilter in the removal of odorants like ammonia (NH3), sulphides and volatile organic compounds (VOCs). The scrubber and BTF units were monitored during two summer periods in two consecutive years (08.
