Implication

Comparative study demonstrates high pollutant removal via sono-electro-Fenton in hospital wastewater, indicating superior energy efficiency and lower chemical demand.

Key Points

To evaluate and compare the performance of Fenton, Sono-Fenton (SF), Electro-Fenton (EF), and Sono-Electro-Fenton (SEF) technologies for reducing chemical oxygen demand and other pollutants in hospital wastewater.
Applied Response Surface Methodology (RSM) to assess operational parameters including Fe2+/FeSO4 concentrations, H2O2 dosage, current density, pH, reaction time, and ultrasound power.
Quantified treatment performance by measuring percentage reductions in chemical oxygen demand (COD), turbidity, and phenol alongside specific energy consumption (SEC).
Fenton achieved 95.13% COD removal, 90.96% turbidity reduction, and 91.67% phenol removal at 97.0 minutes, with Fe2+ and H2O2 concentrations contributing 75.83% and 10.35% to efficacy, respectively.
Electro-Fenton yielded 97.06% COD removal, 91.35% turbidity reduction, and 95.56% phenol removal with an SEC of 12.926 kWh/kg across 56.4 minutes, with FeSO4 and current density driving 52.48% and 24.97% of effectiveness.
Sono-Electro-Fenton achieved 91.04% COD removal, 84.62% turbidity reduction, and 91.67% phenol removal in 56.4 minutes, exhibiting optimal overall efficiency with the lowest SEC (4.3 kWh/kg COD) and lowest FeSO4 requirement (0.2 mM).
