ABSTRACT

During the last three decades, the electrocoagulation (EC) process has known an exemplary renaissance in the field of water and wastewater treatment. Sev-eral researchers focused on applying this electrochemical technology in re-moving diverse pollutants such as pathogens and organic matters. During EC application, the hazards of formation of highly toxic disinfection by-products (DBPs) are more and more proved especially in water containing organic mat-ter and halogens especially chloride. This work presents a brief view on the questions related to such issues and challenges. Great efforts remain to be ac-complished towards the comprehension of the inherent phenomena related to removing both microorganisms and organic matters in the EC method. Using granular activated carbon post-treatment could hugely diminish the levels and toxicity of DBPs. Further, safe multi-barrier methods, such as distillation and membrane processes, have to be adopted.
