Abstract
The batik industry, ranging from household-scale to large-scale industries, generates wastewater containing high levels of organic compounds, dyes, and other pollutants such as COD (Chemical Oxygen Demand) and TSS (Total Suspended Solids), which are difficult to degrade. Wastewater treatment is necessary to reduce pollutant content to meet environmental quality standards. However, treatment methods are often inadequate and costly. Therefore, this study investigates the effectiveness of the Advanced Oxidation Process (AOP) using the electro-Fenton method, which is capable of generating reactive hydroxyl radicals to degrade organic pollutants. The objective of this research is to analyze the effectiveness and optimize the electro-Fenton process in reducing COD, TSS, and color in batik wastewater. The study aims to determine the optimal combination of current intensity, contact time, and molar ratio of H₂O₂:FeSO₄ that yields the highest removal efficiency. The research was conducted using a batch electro-Fenton method with variables including current intensity, contact time, and the molar ratio of H₂O₂:FeSO₄. The resulting data were analyzed using Two-Way ANOVA. Based on the study, the electro-Fenton treatment achieved a COD removal efficiency of 77% under conditions of 4 amperes current, 35 minutes contact time, and H₂O₂:FeSO₄ ratio of 10:0.3. TSS removal efficiency reached 98% at 3 amperes current, 25 minutes contact time, and H₂O₂:FeSO₄ ratio of 10:0.3. Meanwhile, color removal efficiency reached 99.7% at 3 amperes current, 45 minutes contact time, and H₂O₂:FeSO₄ ratio of 10:0.1.
