Abstract
Effects of pH, moisture and flow pattern on the performance of a trickle-bed air biofilter (TBAB) treating benzene, toluene, ethylbenzene and o-xylene (BTEX) waste gas were investigated to establish the optimum operating conditions and design criteria. In the pH range of 7.5–8 and NFR range of 6.02–8.6 l/m 3/h, removal efficiencies of each compound were greater than 80% with a loading of 143 g BTEX/m 3/h. The TBAB appears to be an effective process for controlling BTEX emission with a high loading. Counter-current flow TBAB has the advantages of more uniform BTEX removal and biomass growth in each section than co-current flow TBAB, but suffers from a higher pressure drop across the bed.
