Abstract
This paper is focused on the use of ozone for the removal of dissolved organic micropollutants from natural waters. The overall kinetics of the ozonation reactions is described in terms of two key process parameters: (i) specific ozone utilization rate, w (1/hr), for the raw water to be treated, and (ii) total oxidation rate constants, kT (l/mole-s), of organic chemicals to be removed from the water. A simple experimental methodology is presented to measure the kinetic parameters in natural water samples. We have also provided tools for the estimation of w and kT based on the pH, alkalinity, and total organic carbon (TOC) content of the water. These predictive tools can be used for preliminary design purposes.
