Abstract
A study was conducted to investigate the utilization of mature compost as a biofilter media for the removal of ammonia from the exhaust gases of the composting process. Source-selected organic fraction of municipal solid wastes, digested wastewater sludge and animal by-products were composted in a pilot-scale reactor and the exhaust gas was treated in a biofilter. Due to the high ammonia adsorption and absorption capacity of the compost media, no delay or start-up phase was observed and high removal efficiencies were achieved from the beginning of the experiments. A global ammonia removal efficiency of 95.9% was obtained in the biofilter for a loading rate range of 846-67,100 mg NH3 mâ3 biofilter hâ1. However, an important reduction of ammonia removal was observed when the waste gas contained high NH3 concentration (more than 2000 mg NH3 mâ3), which corresponded with the case of animal by-products composting.
