Abstract

Electrocoagulation has emerged as an environmentally friendly water treatment method by generating coagulants in situ and eliminating the need for chemical additives. Despite its promise, little research has examined the operational characteristics for tropical peat water, which is marked by high acidity and a significant presence of natural organic matter. This study investigates the effects of electrode spacing (1–2 cm) and reaction time (30–90 min) on the decrease of color, total organic carbon (TOC), and turbidity in peat water from South Kalimantan, Indonesia. A Central Composite Design (CCD) was employed in Response Surface Methodology (RSM) to identify optimal conditions. The results indicate that reduced electrode spacing and prolonged reaction time significantly enhance removal efficiency. The ideal parameters were achieved with an electrode separation of 1.514 cm and a reaction time of 74.602 min, yielding 56.16% color removal, 77.02% total organic carbon reduction, and 22.02% turbidity reduction. The high coefficients of determination (R² > 0.95) confirm the models' effectiveness in predicting treatment outcomes. This study demonstrates that CCD-RSM is a reliable tool for optimizing electrocoagulation, and the findings offer practical insights for developing cost-effective systems for treating peat water in tropical regions.
