Application of ozonation process in industrial wastewaters: textile, kraft E1 and whey effluents.
A large variety of organic and inorganic compounds can be found in wastewater from industrial processes. In this work, Advanced Oxidative Processes (AOPs) have been applied for the control of water pollution and the ozonation of different effluents was investigated. Wastewater from textile, kraft E1 and cheese manufacturing processes were chosen as examples of industrial effluents. The efficiency of substrate mineralization has been comparatively analyzed by the decrease in total organic carbon (TOC), color, and toxicity. The results revealed that the ozonation process can be a method for decolorization of effluent, but it is not effective for TOC reduction. The whey effluent was the most recalcitrant wastewater for ozone treatment which produced no TOC removal.
