Effluents coming from potato chips manufacturing have high organic loads and require adequate treatment before discharge to environment. In this study, O 3 /UV/H 2 O 2 advanced oxidation process was applied to treat these wastewaters. With this aim, batch experiments were conducted in a reaction tank equipped with ozone injection and UV irradiation. Process variables were determined to be pH, ozone concentration, reaction time, H 2 O 2 dosage and efficiency of the system was evaluated considering total organic carbon (TOC) removal. Central composite design technique was applied to examine the individual and synergetic effects of the experimental factors. A quadratic model was developed to maximize the TOC removal. Furthermore, operation costs were calculated for different experimental conditions and interactions between process variables and costs were analysed.
