Hydroxyl Radical Oxidation Processes For The Removal Of Triazine From Natural Water

Abstract
The purpose of this study was to point out processes that can provide triazine oxidation via hydroxyl radical production in a water treatment line. We focus our attention on: - oxido-flocculation, using Fe2+, H2O2 - inter-oxidation, using O3, H2O2 and eventually an heterogeneous catalyst. - disinfection, using UV, O3 and H2O2 combinations. Results show that triazines can be removed by all these processes with different efficiencies. At full scale, the O3/H2O2 process presents the best performances from an economical and technical point of view.
