Abstract

The rate of phenol biodegradation by an adapted activated sludge was studied in a completely mixed, continuous-flow reactor with recycle and controlled wasting of the sludge, operated at steady-state conditions at 20.0°C. No substrate inhibition was evidenced in the concentration range covered (up to 360 mg phenol/l in the influent). The results of a series of kinetic runs at the highest influent substrate concentration were interpreted in the framework of the Monod model, obtaining the values of the kinetic parameters. The effect of different sludges and of a different influent concentration was checked. While the latter markedly affects the rate of phenol removal, the change of sludge with another one originally different but similarly adapted influences the kinetics to a lesser extent.
