Abstract
In this research, the elimination of a mixture of toluene and hexane vapors from waste air was studied in a compost biofilter under intermittent condition. The system was operated 10 h a day on the air residence times 0.9, 1.5 and 3 min and 2-3.8 gm-3 of pollutant concentration. Regarding the harsh biological condition of biofilter media such as high pollutant concentration and daily intermittent aeration, reaching the steady-state situation and removal efficiency of 90% lasted about 44 days.
