<p>The increasing demand for efficient and sustainable water treatment technologies has driven the development of advanced systems that integrate hybrid methods to remove organic compounds from produced water (PW). This work presents a novel design, the Digital Baffle Electro-Photo-Fenton Batch Reactor (DBEPB), which combines digital baffle systems with electro-photo-Fenton oxidation processes to improve wastewater treatment efficiency. The hybrid electro-photo methods within a batch digital baffle reactor offer significant advantages in eliminating organic pollutants, particularly in the complex context of produced water treatment. The growing need for clean water worldwide and stringent regulations on dangerous substances are the major reasons for the increased attention given to this sort of design, which removes harmful compounds while improving the quality of the water. The application of hybrid methods to purify produced water is exemplified by the Photo-Electro-Fenton Oxidation (PEFO) method. Several major factors affecting hybrid treatment, such as pH, agitation speed, H₂O₂, and electrolysis time, were discussed systematically for produced water treatment. Key variables such as agitation speed (100–300&#xa0;rpm), pH (3–9), oxidative agent concentration (5–20&#xa0;mg/L), and electrolysis time (10–30&#xa0;min) were optimized using response surface methodology (RSM) and Box-Behnken Design (BBD) using software Minitab-17. The electrolysis was carried out at a constant current of 0.5 A and 25&#xa0;°C. Under the optimal conditions determined for the selected variables, the DBEPB reactor achieved over 99.8% removal of organic contaminants, compared to 91.3% removal with a non-photo reactor. These results confirm that the photo-electro oxidation technique is highly effective in treating produced water contaminated with organic pollutants, particularly at low concentrations in wastewater.</p>
