This study is to investigate the effects of TOC removal by ozonation in the continuous membrane process after Fenton's treatment of textile wastewater. Experiments were conducted to examine the effects of various operating variables on the treatment efficiencies of the combined individual unit operations by ozonation and membrane separation. Ozonation was found to provide very efficient removal efficiency in the process, avoiding the exclusive ozone treatment. It was observed that the ozone-mediated membrane process acts not only as a sieving effects, but also as an oxidizer in promoting the removal efficiency of TOC. Present study in combined continuous process offers strong synergistic effects of the removal of color and TOC on the textile wastewater treatment. A prototype consisting of multiple steps of unit operations associated with ozone was proposed in this work, the proposed continuous hybrid-process including Fenton's oxidation, ozonation and filtration was shown to remove TOC very well to treat the textile wastewater.
