Mohamad Said K.A., Asif S., Mazelan N., Rahman M.R., Hamdan S., Kuok K.K., 2025, Exploring the Effect of Zeolite/ Activated Carbon Variation in Filtration Media for Peat Water Treatment, Chemical Engineering Transactions, 122, 361-366.
Direct consumption of untreated peat water poses health risks due to the presence of humic substances. Hence, this study examines the influence of different ratios of zeolite to activated carbon on removing contaminants from peat water, utilizing a fixed amount of zeolite (30 g) with varying activated carbon weight (0, 10, 20, 30 g). The highest humic content removal was by column D (30 g zeolite: 30 g activated carbon; 1:1 ratio) at 66.67 %, and similar findings for chemical oxygen demand (COD) and total organic carbon (TOC), single column named as column D remove these water quality indicators at 84.45 % and 65.95 %, respectively. The adsorption of humic acid on carbon's surface is attributed to a combination of electrostatic attraction and surface complex formation.
