Summary: The presence of organic and inorganic contaminants in wastewater discharge has a negative impact on the environment. The electrochemical process shows promise for treating these harmful pollutants from aquatic environments. This review focuses on recent applications of electrochemical processes for removing such contaminants. Electrocoagulation, electrooxidation, and electro-Fenton applications have demonstrated effective performance with high removal rates. However, these processes have drawbacks such as the generation of toxic intermediate metabolites, high energy consumption, and sludge formation. The combination of electrochemical and biological treatment has gained importance in large-scale wastewater pollutant removal, improving removal performance and reducing operational costs.

Summary: In this study, a sequential process of electrocoagulation (EC) followed by electrooxidation (EO) was used to remove the chemical oxygen demand (COD) from wastewater generated in an Iraqi vegetable oil refinery. The effects of operating variables on COD removal in EC were investigated, and a mathematical correlation was developed. The optimum removal efficiency of COD by EC was 69.19% and by EO was 96%. When EC and EO were combined, the total COD removal efficiency was 98.72%.

Summary: Electrocoagulation was studied as a method for treating furniture industry wastewater containing polyvinyl acetate (PVAc). The study evaluated the effects of inter-electrode distance, current density, and mode on treatment performance. The results showed that low inter-electrode distance and Alternating Pulsed Current (APC) mode resulted in reduced energy consumption and better treatment performance. Despite the promising results, the treatment procedures were insufficient to meet the legal requirements for water discharge.

Summary: In this study, FWW containing Rhodamine B dye was effectively treated using a simultaneous EC-EO system, achieving high removal of COD and colour. The main pathway for RhB removal was the formation of insoluble, polymerized products in EO and their subsequent entrapment in metal hydroxide flocs formed in EC. The toxicity test showed low adverse effects on seed germination when exposed to treated FWW.
