Abstract

Diclofenac (DCF) is among the compounds that are highly resistant to biological degradation processes and have low removal efficiency in Wastewater Treatment plants. In the current study, DCF removal was examined by using the O3/UV/S2O8 process. All experiments were carried out in a 2-liter lab-scale semi-continuous reactor. DCF concentration was measured by HPLC analytical method. The study began with the optimization of pH, and the effects of other operating parameters, including pH, ozone concentrations, drug, persulfate, and natural organic matter (Humic acid) on the degradation were investigated. The mineralization of Diclofenac was also investigated. The results showed the removal efficiency of 89% and a persulfate concentration of 200 mg/L, pH = 6, DCF = 8 mg/L, and reaction periods 30 min in the O3/UV/S2O8 process. Humic acid was selected as a scavenging compound, which decreased the removal DCF rate from 89% to 76%. So, Sulfate Radical-based technologies show promising results for the removal of these particular pharmaceuticals from the Wastewater Treatment plant.
