ABSTRACT
Electrochemical technologies have been investigated extensively for the removal of a wide range of organic contaminants present in wastewater. Municipal wastewater (MWW) is one of the largest sources of pollution due to its volume and concentration. Therefore, upgrading and treating this hazardous waste has become the urgency to curb this mismanagement of this liquid waste and preserve the environment. Up to date, a number of studies have reported a significant improvement in pollutants degradation efficiency using the electrochemical processes. This chapter briefly discusses the current status of the use of electrochemical treatments and their limitations towards the degradation of all types of organic compounds with the focus on three types of processes, electro-Fenton (EF), anodic oxidation (AO) and electrocoagulation (EC).
