Improvement of Ozone Oxidation and Disinfection Design

摘要

For a long timei the aim of ozonation has been the improvement of the organoleptic qualities of treated water. Disinfection! and particularly virus inactivationi also has been a reason for introducing ozonation steps in the treatment line of a potable water treatment plant. Other purposes of ozonation then have been developed in different fields of application, such as iron and manganese removal, micropollutants oxidation, urban wastewater disinfection! coagulant and flocculant aids, and improvement of biological treatment. During the last few years, numerous studies have been concerned either with the kinetics of ozonation reactions, or the modelling of contact systems. A better fit between these two factors should be found.
