    Abstract:
    Different Advanced Oxidation Processes (AOPs) such as photocatalysis, Fenton-based processes and ozonationwere studied to include one of these technologies within an integrated solution for produced water (PW)polishing. Synthetic PW was prepared adding toluene, xylene, naphthalene, phenol, acetic and malonic acids toa seawater matrix. Despite that in all AOPs studied in this work BTEX and naphthalene were removed, the effi-ciency (in terms of TOC removal) of each treatment varied largely. Among these techniques, photocatalysiswas found to be the less effective for the treatment of PW, as TOC removals lower than 20% were obtained forthe best scenario after 4 h treatment. In the contrary, best results were obtained by ozonation combined withH2O2, where all the organic components were removed, including a high percentage of acetic acid, which wasnot abated by the rest of the AOPs studied. The optimum conditions for ozonation were 4 g h−1O3and1500 mg L−1H2O2at pH 10, where after 2 h a 74% of TOC removal was achieved and the acetic acid eliminationwas 78%. This condition enabled that ozonation process accounted for the lowest electric energy consumptionper order of target compound destruction regarding total organic carbon (TOC).© 2019 The Authors.
