Abstract
For the purpose of the simulation of the kinetics of the reaction of ozone with wastewater in a bubble column, the kinetics can be adequately described by two components and their respective rate constants. Ozone uptake and ozone steady states along a bubble column have been determined. A modeling procedure has been developed that allows us to describe this behavior and to simulate the degradation of micropollutants. For fast (diclofenac) and moderately fast (bezafibrate) reacting micropollutants this model describes their measured elimination well.
ACKNOWLEDGMENT
This study has been carried out on behalf of the Minister for Umwelt and Naturschutz, Landwirtschaft and Verbraucherschutz des Landes Nordrhein-Westfalen' within the framework of the project ‘Untersuchungen zum Eintrag und zur Elimination von gefährlichen Stoffen in kommunalen Kläranlagen Teil 2’. We thank the colleagues at INFU, Dortmund, for the analyses of the micropollutants and Mrs. B. Busch for technical assistance.
