ABSTRACT
Producing activated carbon from inexpensive or readily available agricultural by-products offers both economic and environmental advantages, making it a viable option, this study investigates the optimization of Zinc removal and COD reduction in Beverage Industrial Effluent using a blend of palm kernel shell and calcite as an adsorbent. Through Response Surface Methodology (RSM), experimental conditions were refined to achieve a minimum COD level of 69.49 mg/L and a low zinc concentration of 0.062 mg/L at pH 6, contact time 120 minutes, and adsorbent dosage 1.75g. Further optimization with Box-Behnken Design (BBD) within RSM identified optimal conditions of 124.92 mins contact time, 3.00 g adsorbent dosage, and pH 7.98, resulting in reduced COD (55.3784 mg/L) and Zinc concentration (0.041726 mg/L). Analysis using Fourier Transform Infrared (FT-IR) and X-ray diffraction (XRD) revealed the chemical composition and crystalline phases present in the palm kernel shell activated carbon (PKSAC), while Scanning Electron Microscopy (SEM) showed large pores enhancing zinc uptake. This study highlights the efficacy of PKSAC in treating Beverage wastewater, emphasizing its potential for industrial application in wastewater treatment processes.
