Abstract: During the last decades, the industrial sector has been confronted with important challenges concerning the water treatment. Stricter norms and a rising fresh water cost make a more profound effluent purification, possibly coupled with water reuse, more and more necessarily. In this paper, the potential contribution of the integration of chemical oxidation with biological treatmetn in realising these challenges, has been examined. In this study, the Fenton process and the ozonation process are evaluated based on both conventional analytical measurements and respirometry. During the past decades, respirometry has increasingly been employed to obtain biokinetic characteristics, and it is considered one of the most important information sources in activated sludge process modelling. From the investigated AOPs, the Fenton process leads to the best results based on both degradation of organic pollutants and enhancement of biodegradability. An overall COD degradation by the combined treatmetn between 69% and 86% can be achieved.
