Abstract

A mechanistically-based model of a fixed-film trickle-filter bioreactor for co- metabolic degradation of TCE has been developed. This model incorporates diffusional and kinetic resistances and generates estimates of TCE stripped from the liquid by gas as well as the extent of biological degradation of TCE. The model predictions are consistent with a limited data base. It has isolated the kinetic resistance as the dominant resistance to the degradation of TCE. The model should be useful in determining the optimal conditions for minimizing the stripping of components of interest from the bioreactor liquid phase. It appears the model will be a useful design tool during scale-up operations.
