Abstract

The electro-chemical Fenton (EF) was evaluated for the treatment of fast food chain wastewater at different operating currents with three responses as residual chemical oxygen demand (COD) level, and Fe²⁺ and H₂O₂ concentrations. preliminary experiments showed that EF had the highest COD reduction (91.49%) at the end of two hours compared to conventional Fenton (CF) (83.71%) and electrolysis (18.09%). At the pre-determined Fe: H₂O₂: WW volumetric ratio of 1.25:17:25, the residual COD at all operating currents reached DENR-accepted levels. The model obtained from statistical analysis was significant. However, due to the significant lack of fit, it could not be used for predictive purposes. The Fe²⁺ and H₂O₂ concentrations exhibited non-conclusive results because of the interplay of the regeneration at the electrodes and the consumption via the Fenton reaction. Analysis on the Fe²⁺ concentration resulted to a significant model, but with a significant lack of fit. The 0.8 ampere (A) setting exhibited a high COD removal efficiency at 92.83 percent, reaching DENR-compliant effluent COD at the end of 8 minutes. The cost at recommended operating condition was Php9.95 per cubic meter of wastewater. Although further analysis of other cost components is needed, the EF process might be used for applications with limited land space and those requiring faster treatment times.
