Evaluating the solar Photo-Fenton as photocatalyst process by Response surface methodology to treat the saline water

Abstract

The aim of this study is to investigate to treat saline water by using solar photo Fenton reagent with and without CuO to eliminate the organic pollutants by using Solar energy in order to prevent the membrane fouling. However, the experiment executed according to the Two-level factorial design with Response surface methodology (RSM) to determine the Total organic carbon (TOC), Total dissolved solid (TDS), Salinity and Conductivity removal efficiency under the optimum operational conditions. As the results shown the maximum removal efficiency were TOC = 64.094%, TDS = 19.230%, Salinity = 21.989% and Conductivity = 19.267% respectively. Moreover, increasing in CuO concentration and reaction time, TOC removal increased and time of reaction increases in presence of Fe+2 dosage, the TOC removal will also increase. And, the TDS removal efficiency drops by increase the amount of CuO(g/L) and Fe+2(g/L). Experimental results demonstrate that the photo-Fenton process is feasible for the treatment of wastewaters containing hydrocarbons, even in the presence of high concentrations of salt.
