Abstract

Peat water has potential as a source of raw water, especially in areas with abundant peat water supplies; however, its use is still hampered by high organic content and color, thus requiring effective treatment. This study aims to analyze the performance of a combination of Granular Activated Carbon (GAC) and zeolite in a fixed-bed column for treating peat water after coagulation–flocculation, determine the optimal adsorption conditions, evaluate changes in adsorbent characteristics through Brunauer–Emmett–Teller (BET) analysis, and analyze the adsorption kinetics using the Thomas and Yoon–Nelson models. Preliminary treatment was performed via coagulation–flocculation using polyaluminum chloride (PAC) and quicklime, followed by up-flow adsorption using varying compositions of GAC and zeolite and bed depths of 5, 7.5, and 10 cm at a flow rate of 5 mL/minute. Process performance was evaluated based on the parameters of pH, Chemical Oxygen Demand (COD), Dissolved Organic Matter (DOM), Total Dissolved Solids (TDS), and color. The results of the study showed that a 75:25 zeolite:GAC combination at a bed depth of 10 cm provided the best overall performance, with a reduction in COD from 432 to 16 mg/L (96.3%), DOM from 6.6504 to approximately 4.13 mg/L (37.9%), TDS from 164 to 88 ppm (46.34%), and color from 20.3 to approximately 13 Pt-Co (36%). Kinetic analysis shows that the Thomas and Yoon–Nelson models indicate that the 0–90-minute observation range has been able to describe the occurrence of breakthrough, but does not yet cover the entire curve development until the column reaches saturation. Overall, the combination of zeolite and GAC in a fixed-bed column has the potential to improve the quality of peat water after coagulation–flocculation, with the composition of the adsorbents and bed depth serving as factors that influence the performance of the process. Keywords: peat water, adsorption, GAC, zeolite, fixed-bed, adsorption kinetics
