Electrochemical Advanced Oxidation Processes: A Case Study on Application of Fered-Fenton for Waste-Activated Sludge Treatment

In last two decades, electrochemical advanced oxidation processes have attracted scientists' attention as efficient and environmentally friendly technologies to upgrade and eliminate deficiencies of traditional wastewater and sludge treatment processes. In this study, besides an overview on electrochemical advanced oxidation processes based on Fenton's reaction chemistry, highly efficient Fered-Fenton technology which is a combination of Fenton and electrochemical processes is investigated. In this regard, results of the research group studies on a setup of Fered-Fenton system for waste-activated sludge treatment are presented. The results of these studies which have been conducted comprehensively for the first time, demonstrate Fered-Fenton process efficiency in degrading organics, heavy metals, nutrients and pathogens.
