Hydrogen sulfide (H2S) and ammonia (NH3) have generally low odor thresholds, high toxicity to human health, and potential corrosive effects to downstream infrastructure and equipments. Biofiltration is a cost-effective and environmental friendly technology for the control of odorous compounds. Exhausted carbon is a hazardous waste from the H2S adsorption process, which must be either regenerated or disposed of in a landfill. This study is to develop a highly efficient and economical biofiltration process for the co-removal of H2S and NH3 using exhausted carbon as packing material.
