Abstract: Due to their durability and bio accumulative capacity, the ever-increasing discharge of chlorinated hazardous contaminants from industrial sources presents a major environmental concern. An integrated electrochemical treatment procedure followed by improved post-treatment techniques is the subject of this work, which aims to efficiently remove chlorinated pesticide industrial wastewater (PIW). Using conventional physicochemical techniques, we analyzed wastewater samples taken from an industrial location. The electrochemical oxidation process was improved using a range of pH settings and reaction periods with a variety of electrode materials (Fe, SS, Ti, and Al) as part of the core treatment. The electrochemical system was observed for pollutants degrading every ten minutes and powered by a controlled direct current source (up to 84V). The treated effluents were subjected to further processing steps including activated carbon filtration, photochemical oxidation, and son chemical treatment (33 kHz ultrasonic bath, 1255 W) in order to improve mineralization and finish breaking down the remaining organics. Chlorinated pollutants were degraded more efficiently using the integrated strategy. The calculation of removal efficiencies using APHA standards shows that this combined treatment technique has the ability to effectively remediate industrial effluents contaminated with persistent organic pollutants.
