Abstract
CATAZONE is a new process of heterogeneous catalytic ozonation in which water is ozonated in the presence of a solid catalyst composed of titanium dioxide. The efficiency of this O3/TiO2 system has been compared to the two well-known oxidant systems: ozone alone and ozone combined with hydrogen peroxide. This comparison was undertaken on three models of natural organic compounds : an aquatic fulvic acid, a protein and a disaccharide. The first results showed the following order of relative efficiency: O3/TiO2 > O3/H2O2 > O3 as far as Total Organic Carbon (TOC) removal was concerned.Keywords
