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 a 6-L three section biofilter containing a mixture of compost (60%) and wood chips (40%). The system was operated at 30±1oC. 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 (6-114 g/m3.hr), in detention time of 48 seconds and media moisture of 50-55% were studied to evaluate the removal efficiency of biofilter. Results indicated that all the influent TEA with below concentration of 180 ppm was removed with more than 90% efficiency. In concentration of 180 ppm, more than 90% TEA was hydrolyzed to ammonia in the pH range of 8-9. About 1/3 of biodegraded nitrogen was N-NH3 (gas), 1/3 was converted to NH4+ and 1/3 was converted into nitrate and organic or cell nitrogen. Nitrogen forms were varied over time and with the height of the packing. In certain conditions of this research, the biodegradation of TEA was good but convertion of nitrogen to nitrate was not so well accepted.
