Abstract

The effect of current on the chemical Oxygen Demand (COD) reduction on the Electrochemical Fenton oxidation treatment of polymer lens manufacturing wastewater was studied. Other treatment factors correlating with current variation like Fe²⁺ and H₂O₂ consumption rates were also investigated using a laboratory-scale Electrochemical Fenton set-up. Time Profiling for two hours at different current levels was performed in order to acquire a general trend for COD and reagent consumption rates. Statistical analysis showed that a quartic mathematical model was the recommended model to fit the data. However, a significant lack of fit on the coded equation generated was obtained. The general trends observed from the results were: increased COD removal efficiency and reagent consumption rates as the amount was increased. The results showed that the highest current setting of 2.5A at 2.3 minutes, was the recommended operating condition with the least energy consumption and partial treatment cost (PhP 30/m³) to achieve DENR compliance (COD).
