A process for phenol biodegradation using biofilms was studied, using a synthetic waste to simulate industrial wastewater with high phenol concentrations. The aim of the experiments was to verify the influence of the aeration of 0.7, 1.6, 2.3 vvm in the kinetics of phenol biodegradation. In the best experimented conditions used that were: packed bead reactor, ceramic spheres support and flow rate of 2.3 vvm, was achieved phenol removal efficiency near 96%.
