Abstract

A graphical procedure for assessing the nature of substrate penetration within a biofilm is developed. This procedure, which is based on a measure of the effectiveness of substrate utilization by biofilm microorganisms, is used to determine when simple analytical solutions of biofilm models can be used accurately. These analytical solutions correspond to extreme values of bulk substrate concentration and cases where the biofilm is fully penetrated or deep. Minimum values of the effectiveness are related to biofilm thickness.
