ABSTRACT
276Environmental engineering science in today’s scientific generation is moving at a drastic pace. Vision of science, technological validation, and the visionary scientific advancements will lead a long way in the true realization of environmental sustainability. Sustainability of the environment is a key issue today. Human civilization is slowly and steadily moving toward a greater vision of green science and technology. Ecological imbalance, environmental catastrophes, and industrial water pollution have urged the scientific domain to gear up for new innovative technologies. At this critical juncture of human history and time, the global wastewater challenge is formidable. Today, industrial wastewater treatment stands in the midst of deep introspection and unmitigated crisis. In such a crucial juncture of human history and time, the main urge of human civilization is toward protection of environment. The author skillfully delves deep into the world of novel separation processes such as membrane science and nontraditional environmental engineering techniques such as advanced oxidation processes. Hazardous substances are recalcitrant to primary and secondary treatments; so the need arises for tertiary treatment such as advanced oxidation processes. The author also delineates the immense potential of ozonation and other advanced oxidation processes (AOPs) techniques. Vision of science, the unmitigated challenges, and the scientific urge to excel are the torchbearers toward a greater visionary world of chemical process engi neering and environmental engineering science. The aim of this study is to review the use of ozone oxidation, titanium dioxide/UV light process, hydrogen peroxide/UV light process, and Fenton’s reaction procedures in wastewater treatment. The pros and cons of the processes are highlighted in detail and precision. The author also deeply observes and informs the readers the success of novel separation processes such as membrane separa tion processes in separating recalcitrant chemicals in industrial wastewater. The vision and the challenge of this treatise unravel a new chapter in the research and development arena of novel separation processes and nontraditional environmental engineering techniques.
