Randomized trial evaluates the hybrid PSP-EC process effectiveness in reducing pollutants in industrial wastewater, suggesting improved treatment strategies.
Key Points
This study aims to evaluate the effectiveness of the hybrid PSP-EC process for removing contaminants from industrial wastewater.
Optimization of pH (3-11) and Peach Seed Powder (PSP) dosage (0.01-0.2 g) for natural coagulation.
Standalone electrocoagulation trials with Fe/Al electrodes at varied current densities (1.33-4.00 mA/cm²).
Response Surface Methodology (RSM) used to model interactive effects of operational variables on treatment efficiency.
Combined hybrid process achieved 99.05% turbidity, 98.84% TSS, 95.43% COD, and 93.24% NH₃-N removal.
Maximum reductions of 90.78% COD, 55.06% NH₃-N, 92% iron, and 99% zinc obtained under optimal conditions.
Enhanced removal efficiencies for color (96.6%), TSS (93.74%), zinc (93.56%), and aluminum (57.54%) were noted.
