Biological phenol degradation was performed experimentally in a gas‐liquid‐solid fluidized bed bioreactor using a mixed culture of living cells immobilized on activated carbon particles. A comprehensive model was developed for this system utilizing double‐substrate limiting kinetics. The model was used to simulate the effects of changing inlet phenol concentration and biofilm thickness on the rate of biodegradation for two different types of support particles. The model shows that gas‐liquid mass transfer is the limiting step in the rate of phenol biodegradation when the phenol loading is high.
