Abstract: | ![]() There is a renewed interest in predicting RCT following growing evidence that AOP is effective against many emerging contaminants. Five surface waters were investigated to evaluate the OH-radical activity using the RCT concept, predict RCT using traditional water quality characteristics and predict contaminants removal by ozonation and peroxone. It was shown that RCT was dependent on water quality characteristics and could be modeled (R2 = 0.92), using water characteristics and treatment conditions. Predictions of MIB oxidation closely matched the published data of Kawamura (2000 Kawamura, S. 2000. Integrated Design and Operation of Water Treatment Facilities, 2nd, New York: John Wiley & Sons, Inc. [Google Scholar]) and bench-scale assays performed on one of the water under investigation. |
