    Steady-state performance characteristics of a trickle bed reactor (TBR) and a biofilter (BF) in loading experiments with increasing toluene/xylenes inlet concentrations while maintaining a constant loading rate of hydrophilic components (methyl ethyl and methyl isobutyl ketones, acetone, and n-butyl acetate) of 4 g m-3 h-1 were evaluated and compared, along with the systems’ dynamic responses. At the same combined substrate loading of 55 g m-3 h-1 for both reactors, the TBR achieved more than 1.5 times higher overall removal efficiency (REW) than the BF. Increasing the loading rate of aromatics resulted in a gradual decrease of their REs. The degradation rates of acetone and n-butyl acetate were also inhibited at higher loads of aromatics, thus revealing a competition in cell catabolism
