Abstract
ABSTRACT Experiments have been conducted to investigate the performance of a bench-scale biotrickling filter for removing benzene from benzene-laden air. The operating parameters are inlet loading rate of benzene, empty bed retention time (EBRT), liquid recirculation rate, temperature, and pH. The elimination capacity of benzene from benzene-laden air increases with increasing the EBRT and the inlet loading rate. Further, the removal efficiency increases as liquid recirculation rate decreases. However, it decreases as inlet loading rate increases. The optimum pH and temperature for the removal efficiencies are in the range of 7.0 ~ 7.5 and 25 ~ 40°C, respectively.
