In an era of continually accelerating industrial growth and global climate change, the necessity of controlling environmental pollution and increasing clean water availability has promoted the development of advanced water treatment technologies. Ozone is one of the most active, readily available and safest oxidizing agents, and it has been widely used for water purification and wastewater treatment since the operation of the first ozonation-based drinking water plant in Nice, France, in 1906.
The ozonation reaction is accomplished by direct ozone oxidation and indirect oxidation with in situ generated, highly oxidizing radical species typically including hydroxyl radicals, and the latter means is particularly powerful to mineralize a wide variety of micropollutants. Over the years, in order to improve the hydroxyl radical yield to ultimately attain a maximized overall efficiency, different types of active solid catalysts were designed, fabricated and applied in ozonation-based systems and various integrated technologies by combining ozonation with other oxidation processes (e.g., photocatalytic/electrochemical oxidation, ultrasonic treatment, other oxidants that have been developed).
This book provides an overview of the most studied catalytic ozonation process and advanced ozone-integrated processes, some of which have been largely implemented for practical water treatment, given their proven efficacy, attractive economics and sustainability. The fundamental mechanism, kinetic modeling, operational conditions’ impact on process performance, and economics are discussed. In particular, the book summarizes the synthesis methods, structure-property-performance relationships and stabilities of the best-in-class solid catalysts and provides examples of pilot-scale and full-scale plants as well as future research needs toward developing scalable applications in a real world for each process.
Most books available today concentrate on the general aspects of the typical catalytic ozonation process, seldom dealing with the best-in-class solid catalysts, advanced ozone-integrated processes and their applicable situations. This book, written by the leading scientists of the field from different nations, fills the gap. Anyone interested in the latest scientific and technological achievements in advanced ozonation processes, including water industry professionals, university professors, consulting scientists and engineers, and students, will find this book useful.
