Oxygen transfer during aerobic biodegradation of pollutants in a dense activated sludge slurry bubble column: Actual volumetric oxygen transfer coefficient and oxygen uptake rate in p-nitrophenol degradation by acclimated waste activated sludge

For the aerobic biodegradation of p-nitrophenol (PNP) by acclimated waste activated sludge, the dynamic models for the dissolved oxygen mass balance and PNP degradation kinetics with the proposed correlations for volumetric oxygen transfer coefficient and oxygen uptake rate could successfully simulate the concentration profiles of dissolved oxygen and PNP during the time course of an aerobic biodegradation of PNP.
