dc.description.abstractIn this study, PS/UV-C and PMS/UV-C processes were used for the removal of pollutants from domestic and industrial wastewater. The effects of initial oxidant concentration, initial pH value and reaction time on COD and TOC removal efficiencies were determined by laboratory-scale, batch experimental studies. In the results of the study, the highest removal efficiency was obtained with PS/UV-C process at 25 mM oxidant concentration, pH 7 and at the end of the reaction time of 60 min, and the COD and TOC removal efficiencies were found to be 90.5 and 90.8%, respectively. In the study, unit and specific electricity consumptions were also calculated in order to compare the costs of PS/UV-C and PMS/UV-C processes. The optimum removal efficiency for PS/UV-C was obtained at pH 7 and 25 mM PS concentration and at 60 min of reaction time. Unit electricity consumption (E-EO) values for COD and TOC parameters were calculated as 39.1 and 38.4 kWh/m(3), respectively, and specific electricity consumption (E-EM) as 80.5 and 181.8 kWh/kg, respectively. As a result of the kinetic studies obtained f or COD removal in both PS/UV-C and PMS/UV-C applications, it was determined that the reaction was compatible with the second-order kinetic model. PS/UV-C reaction rate was obtained 2 times higher than PMS/UV-C. It has been determined that PS/UV-C process is a more suitable process in terms of removing COD and TOC compared to PMS/UVC in the treatment of this urban wastewater.
