Background: Wastewater from textile industries poses serious environmental concerns due to high levels of color, chemical oxygen demand (COD), solids, and salts. This study evaluated a continuous horizontal-flow electrocoagulation (EC) reactor with aluminium electrodes and specially designed aluminium baffle walls for treating actual textile effluent. The baffle walls enhanced mixing, reduced short-circuiting, and ensured uniform water flow.
Methods: Quadratic models were developed to assess pollutant removal, revealing that current density had the greatest positive effect, while negative quadratic terms indicated optimal operating ranges. Significant interactions between current density and detention time demonstrated synergistic effects. Model reliability was confirmed by high R² values (>0.93) and minimal lack-of-fit (p >0.05). The influence of current densities (20–80 A/m²) and detention times (5–45 min) on turbidity, color, COD, total suspended solids (TSS), and total dissolved solids (TDS) removal was investigated.
Results: Results showed improved removal efficiencies with increasing current density and detention time, particularly within 20–25 minutes. Under optimal conditions, removals reached ~99% turbidity, 98–99% COD, nearly complete TSS, 72% color, and 68% TDS. Response Surface Methodology identified optimal conditions of 20 mA/cm² current density and 60 min detention, achieving 92% COD and 97% color removal at 2.9 kWh/m³ energy consumption.
Conclusion: The baffle-wall EC reactor demonstrated stable, scalable, and energy-efficient performance, highlighting the importance of optimized electrical parameters and reactor flow configuration for sustainable textile wastewater treatment.
