Night soil sludge was enriched to foster nitrifying bacteria by the addition of ammonium sulfate, and the enriched mixed culture of nitrifying bacteria obtained was inoculated to peat. Ammonia gas was introduced to the peat biofilter by gradually increasing from 48 to 265 ppm, at a space velocity from 87 to 437 h(-1). with an ammonia load from 0.5 to 5.8 g N kg(-1) dry peat d(-1) for 103 days. The ammonia removal characteristics observed over a 103 day experiment were as follows: an average ammonia removal ratio of 97 %, complete removal capacity of 4.5 g N kg(-)1 dry peat d(-1), maximum removal capacity of 5.6 g N kg (-1) dry pear d(-1), maximum removal rate of ammonia, V-m of 46.1 g N kg dry peat d(-1). The ammonia removal capacity of this peat biofilter was enhanced significantly and the maximum removal capacity and maximum removal rate were the highest among the data reported to date.
