Abstract
Performance of a pilot Biofiltration system in removing of Triethylamine (TEA) vapor from air stream was evaluated in this study. Experiments were conducted with two 6-L three section biofilters containing a mixture of compost (60%) and wood chips (40%). The systems were operated at 20±2 and 30±1 ?C. Municipal activated sludge was added initially to promote microbial growth and the systems were started after initial adaptation period of 40 days. Various loading rates (8-130 g/m3.hr) and detention times (40-60 seconds) were studied to evaluate the effect on performance of biofilter for TEA removal. Results indicated significant decrease in EC for HRT < 48 s but negligible differences were observed between 60 and 48 s. TEA removal in section one was significant higher than the other two. Maximum E.C. of 61 g/m3.hr at HRT of 48 second, humidity of 50-55 %, and loading rate of 90.6 g/m3.hr was observed for the reactor A. Maximum E.C. of 72 g/m3.hr at HRT of 48 s, humidity of 50-55 %, and loading rate of 114.4 g/m3.hr was observed for the reactor B having a higher temperature.
