Advanced Oxidation Processes for Waste Water Treatment: Emerging Green Chemical Technology is a complete resource covering the fundamentals and applications of all Advanced Oxidation Processes (AOPs). This book presents the most up-to-date research on AOPs and makes the argument that AOPs offer an eco-friendly method of wastewater treatment. In addition to an overview of the fundamentals and applications, it details the reactive species involved, along with sections on reactor designs, thus helping readers understand and implement these methods.
