✦ Synopsis

Reahstlc mathematical models are essential for the scahng-up or the design of blofilters. However, the mathematical models which describe the steady-state and the transient operation of biofilters are very limited. Although some of these models are based on restrictive assumptions, they have been widely used in industry for designing actual blofilter units. This study gives detailed analysis and comparison between these models. The asymptotic behavior of recent models are presented. The results show that diffusion is an important phenomenon which should not be neglected in developing biofilter models, and that neglecting oxygen transport and its effects on growth kinetics will give unrealistic values for the effective as well as the actual film thickness.
