Biotrickling filter (BTF) is one of the emerging and promising technologies for pollutant treatment. As well, activated sludge considers an enriched sample of denitrifying bacteria, which, is required for nitrous oxides treatment. In this study, a BTF system inoculated by an activated sludge was used for N2O removal from a waste gas stream under anoxic condition. The result showed a 70 % removal at N2O initial concentration of 5807 ppm. Moreover, the filter achieved elimination capacity of 49 g N2O m-3 h-1 of N2O at empty bed residence time (EBRT) of 6.7 min and 1 g/l glucose as the carbon source.
