ABSTRACT

The objective of this study was to investigate the biodegradation of gaseous benzene and ethylene in biofilters filled with granular activated carbon. As the results of this study, the benzene biofilter was capable of achieving benzene removal efficiency as much as 96% at a residence time of 2 min and an inlet concentration of 220 ppm. During operation with an inlet benzene of 220 ppm, the maximum elimination capacity of the biofilter was 483 g of CiHtJm1 • day. The ethylene biofilter was capable of achieving ethylene removal efficiency as much as 100% at a residence time of 14 min and an inlet concentration of 290 ppm. During operation with an inlet ethylene of 290 ppm, the maximum elimination capacity of the biofilter was 34 g of C^H^m3 • day. The biofilter could provide an attractive treatment technology for removing individual and mixed benzene and ethylene.
