Electrochemistry for the Environment


Book Description

Wastewater treatment technology is undergoing a profound transformation due to the fundamental changes in regulations governing the discharge and disposal of h- ardous pollutants. Established design procedures and criteria, which have served the industry well for decades, can no longer meet the ever-increasing demand. Toxicity reduction requirements dictate in the development of new technologies for the treatment of these toxic pollutants in a safe and cost-effective manner. Fo- most among these technologies are electrochemical processes. While electrochemical technologies have been known and utilized for the tre- ment of wastewater containing heavy metal cations, the application of these p- cesses is only just a beginning to be developed for the oxidation of recalcitrant organic pollutants. In fact, only recently the electrochemical oxidation process has been rec- nized as an advanced oxidation process (AOP). This is due to the development of boron-doped diamond (BDD) anodes on which the oxidation of organic pollutants is mediated via the formation of active hydroxyl radicals.




Enhanced Electrochemical Advanced Oxidation Processes for Wastewater Sludge Stabilization and Reuse


Book Description

The growing quantities of waste sludge generated in municipal and industrial wastewater treatment plants containing various organics and other contaminants require novel treatment technologies that are capable of achieving significant removal efficiencies and producing reusable sludge products. As a response, a large variety of advanced oxidation processes (AOPs) have been investigated to remove the present contaminants from wastewaters and limited cases of waste sludge. Multidisciplinary researches have been carried out accordingly. In this regard, electrochemical advanced oxidation processes (EAOPs) have emerged as novel environmental-friendly and effective treatment technologies for the elimination of several organic contaminants. Considerable validation of these methods has been performed at both the bench-scale and pilot-scale. Although a promising new technology, the mechanisms involved in the oxidation of organic compounds during electrochemical advanced oxidation processes and the corresponding environmental impacts have not been completely addressed until now. This book aims at the electrochemical advanced oxidation processes occurrence from different points of view, describing its related technologies, providing an assessment of the development and efficiency, and highlighting various aspects of waste activated sludge stabilisation and reuse accordingly in five chapters. In the first chapter a brief review to waste sludge stabilisation and reuse has been presented. The second chapter provides an overview to advanced oxidation processes. The third chapter describes the various electrochemical advanced oxidation methods. Chapter four presents and discusses the own experimental investigations results employing the Fered-Fenton EAOP. The modeling of the results of the own experimental studies results by means of Taguchi method and artificial neural networks has been performed in the fifth chapter. The main goal of this book is to gather different updated viewpoints according to the electrochemical advanced oxidation processes and to provide the own experimental studies results accordingly in order to present students, researchers, engineers and managers with useful knowledge in this regard.
