Abstract
Iron electrocoagulation (Fe-EC) is a wastewater remediation method that eliminates various contaminants through the application of an electric current across iron electrodes. In this study, the efficacy of two Fe-EC procedures for eliminating chemical oxygen demand from soybean oil refinery wastewater was assessed. The first procedure entailed treating the wastewater by directly exposing it to the electrodes, while the second procedure comprised treating it with electrogenerated Fe coagulant flocs. The effects of operating factors: initial pH (4, 7 and 9) and applied current (0.1, 0.2 and 0.4 A) were examined. The study also sought to simulate the EC adsorption mechanism using SuperPro Designer software. The results showed that COD removal efficiency ranged from approximately 84% to 95% for both approaches with maximum removals of 93.61% and 94.56% by direct Fe-EC and preformed flocs, respectively. The most successful simulation of the adsorption process produced COD reductions ranging from 87.31 to 91.31%, using a two-stage reaction involving one iron (III) hydroxide molecule and five soybean oil molecules.
