Biofiltration has been identified as a promising method of odor, VOCs and air toxic removal from waste gas streams because of low capital and operating cost, low energy requirements and an absence of residual products requiring further treatment of disposal. Because biofiltration units are microbial systems in-corporationg microorganisms grown on a porous solid media like compost, peat, soil and mixtures of these materials, there is a need to study of the adsorptive behavior of these supports. The purpose of this study was to investigate the major parameters of adsorptive process. We adsorbed VOCs onto peats and bark, and examined the correlations between the interphase mass transfer coefficients and transfer units, at different stream flow rates, VOCs inlet concentrations and bed lengths.
