The dimensionless steady-state flux, J*, of substrate into a biofilm can be expressed as a function of the concentration of substrate in the bulk, Sb*, the thickness of the stagnant liquid layer surrounding the biofilm, L*, and the minimum concentration of substrate capable of sustaining growth, Smin*. Using a simplified algebraic expression that relates J* to Sb*, L* and Smin*, a series of nomograms were developed that give the performance of completely mixed (fluidized-bed) and plug-flow (packed-bed) biofilm reactors as a function of process parameters such as hydraulic retention time, kinetic constants and hydrodynamic conditions. The nomograms are simple to use and provide a tool for analyzing the performance of such reactors based in fundamental principles.
