Comparative performance of bio filter packing materials for waste gas treatment

Abstract

A study was conducted to evaluate the removal efficiency of NH3 and H2S emitted from an industrial waste gas source by biofiltration. Four types of packing material were used and NH3 and H2S in the contaminated air stream, ranged between 43-90 ppm and 70-100 ppm respectively. The experiments were carried out over an effective period of 45 .days. Results indicate that 100% removal efficiencies of NH3 and H2S can be achieved for coconut fiber/tobacco compost and peat/wood chips mediums.
