Abstract
This paper is focused on the use of ozone for the elimination of manmade organic micropollutants from drinking waters and waste effluents requiring advanced treatment. A mathematical model was developed to simulate the physical transport and chemical oxidation phenomena prevailing during the process of ozonation. A packed column reactor was constructed in order to test the aptness of the process model. After determining the fluid-dynamic and mass transfer properties of the reactor, stock water solutions spiked with toluene were brought into contact with gaseous O2-O3 mixtures. Toluene removal efficiencies observed under different experimental conditions then were compared with the model predictions.
