Performance Optimization of PAC and Activated Carbon in COD Reduction for Palm Oil Wastewater Treatment

Waste, COD, PAC, Activated Carbon, AdsorptionAbstract
Palm oil industrial processing generates two types of waste: solid and liquid. Solid waste, such as empty fruit bunches, fibers, and shells, is commonly managed through designated disposal facilities. Meanwhile, liquid waste requires proper treatment before being discharged into the environment. One of the essential parameters in wastewater treatment analysis is Chemical Oxygen Demand (COD). This study aims to determine the optimal conditions for COD reduction using the Jar Test method by comparing two coagulants: Poly Aluminium Chloride (PAC) and Activated Carbon. In the treatment of palm oil mill wastewater using PAC, the optimal reagent concentration was found to be 80 ppm, achieving a COD reduction of 29.51%. For the adsorption process with a PAC-Activated Carbon mixture, the optimal activated carbon concentration was 4 g, resulting in a COD reduction of 48.79%. The findings of this study indicate that optimizing coagulant dosage and coagulation-adsorption conditions significantly enhances wastewater treatment efficiency in reducing COD levels.References
