ABSTRACT
The world of environmental engineering is witnessing one paradigmatic shift in science over another. The frequent environmental disasters, the stringent environmental regulations and the grave concerns of environmental sustainability have urged the scientific domain to move toward newer technologies and newer innovations. Technology and engineering science today stands in the midst of deep vision and introspection. Technological vision and scientific objectives of ozone oxidation of industrial wastewater need to be reenvisioned and readdressed at each step of scientific endeavor. Hazardous organic wastes from industrial, military, and commercial operations represent one of the foremost challenges to environmental engineers. This chapter broadly discusses the immense potential of advanced oxidation techniques primarily ozonation in the treatment of industrial wastewater. Advanced oxidation processes (AOPs) are viable 110alternatives to the incineration of wastes, which has many disadvantages. This chapter provides a detailed overview of theoretical basis, efficiency, economics, design, and modeling of different AOPs (combinations of ozone and hydrogen peroxide with ultraviolet (UV) radiation and catalysts). The author of this chapter pointedly focuses on the immense success and tremendous viability of scientific endeavor in the field of ozone oxidation of industrial wastewater. The scientific vision and the deep scientific comprehension of ozone reactions with inorganic and organic compounds are delineated in details in this chapter. Ozone is a powerful oxidizing agent. Second only to fluorine is the oxidizing power of the ozone and has many uses including but not limited to water purification, bleaching of materials such as paper, synthetic fibers, Teflon, waxes, flour, and other products, treatment of wastes in industry, deodorization, and sterilization. Ozone is a safe alternative to chlorine products which performs the same functions without the undesirable side effects; it is not harmful to the environment since it is made from oxygen and decomposes to oxygen. Scientific introspection, the deep scientific insight, and the futuristic challenges will go a long way in the true emancipation of environmental engineering techniques.
