Abstract In this study, the efficiency of ozone to degrade organic compounds of nuclear laundry water was studied at different pH and temperatures and at elevated temperature with hydrogen peroxide. The degradation of non-ionic surfactant and other organic compounds was analyzed by COD, TOC, BOD and molecular weight distribution measurements. Zeta potential measurements were also performed in order to interpret the obtained results. The most favorable degradation conditions were at pH 7 with 43%, 34% and 61% reductions of COD, TOC and BOD, respectively.
