Electro-coagulation (EC) and electro-oxidation (EO) are based on the principle of introducing an electrical current to induce a chemical reaction in water, causing the destabilization of most pollutants such as suspended particles, bacteria, viruses, dissolved materials, metals, hydrocarbons, and many organics. The low energy consumption and absence of chemical utilization with the potential recovery and reuse of treated water makes EC and EO truly green technologies for water/wastewater treatment. EC- and EO-based electrochemical water treatments as a green technology have a major advantage in terms of total size flexibility and are applicable in both urban and rural areas.

This book provides state-of-the-art technologies of EC and EO applications in various water and wastewater treatment processes. Chapter 1 introduces general principles and the basics of electro-coagulation. Chapter 2 discusses the origins and principles of the electro-coagulation process. Chapter 3 discusses the origins and principles of the electro-oxidation process. The mathematical modeling of the electro-coagulation (Chapter 4) and electro-oxidation processes (Chapter 5) are also presented respectively. Chapters 6, 8, 10, and 12 provide the fundamental and recent developments of EC-based technologies, including various treatment techniques (Chapter 6), environmental applications of electro-coagulation processes (Chapter 8), comparative studies between electro-coagulation, adsorption and chemical precipitation (Chapter 10), and full-scale application of electro-coagulation processes (Chapter 12). Topics related to EO-based techniques and processes include combined electro-oxidation (Chapter 7), environmental applications of EO processes (Chapter 9), comparative studies between EO and other oxidation processes (Chapter 11), and full-scale applications of EO processes (Chapter 13). Chapter 14 discusses the cost comparison of EC/EO processes with other clean-up technologies, and Chapter 15 presents the challenges and future perspectives of the EC and EO processes.

We hope this book will be of interest to students, scientists, engineers, government officers, process managers, and practicing professionals. As a reference, this book will help readers readily find the information they are looking for.
