A composted peat moss and chicken manure blend was used to degrade benzene, toluene, and xylenes (BTX) in a 50-L laboratory-scale biofilter. Temperature, moisture content, and oxygen consumption rate of the filter material were examined for 2 weeks. The biofilter was operated with two superficial gas velocities and an inlet BTX concentration ranging between 1,974 and 3,611 mg m{sup {minus}3}. The elimination capacity (EC) for the whole bed reached a maximum value of 82.0 g m{sup {minus}3} h{sup {minus}1}, with a BTX load of 91.8 g m{sup {minus}3} h{sup {minus}1}. The moisture content of the filter material varied from 53.6 to 31.5 wt% and 62.5 to 65.0 wt% at a height of 15 and 86 cm, respectively. The EC of each section of the biofilter was affected by the moisture content through the bed.
