| Oxidation processes may be applied for micro-pollutant elimination in water treatment. In this paper a comparison between the use of ∙OH radicals (advanced oxidation processes, AOPs), ozone, chlorine, chlorine dioxide and ferrate is made. The efficiency of these processes depends on the stability of the oxidant in a specific water and the achievable exposures. In addition, the kinetics of the reaction of the oxidants with the target compounds are very important and together with the exposure control the efficiency of a process. Furthermore, full mineralization of target compounds can rarely be achieved in water treatment. Therefore, we need information on possible oxidation products and their biological activity. In addition, the formation of oxidation/disinfection by-products needs to be considered. They result from the reaction of oxidants with components of the water matrix and specific micropollutants. |
