Abstract |
Steady-state substrate utilization in biofilms has traditionally been modeled by coupling Fickian diffusion with Monod reaction kinetics. An inherent assumption in most of the previous models was that the pH remains constant within the biofilm. Experiments have shown differences between the pH in the bulk solution and in the biofilm. A fundamental approach incorporating the effects of pH in any chemical or biological system involving diffusion with reaction is presented. The approach is applied to a steady-state model of substrate utilization in carbon-limited algal biofilms. (Copyright (c) ASCE 1993.) |
