Abstract

Acid mine drainage is a liquid waste formed by the reaction between sulfide-containing rocks and water and air, resulting in sulfuric acid that lowers pH (≤ 4) and increases the concentration of Fe and Mn elements. This condition can threaten aquatic ecosystems and human health. It is necessary to carry out a processing method according to Government Regulation Number 22 of 2021 class 1 water quality standards, including filtration and adsorption. Commercial activated carbon can be used as an adsorbent in acid mine drainage treatment. During its operation, activated carbon will lose its ability to adsorb heavy metals. Breakthrough is the point where the effluent concentration will increase due to the adsorbent's ability to saturate. The adsorption process in this study is continuous using a fixed bed column reactor column diameter of 3 cm with a variation of activated carbon thickness of 20 cm, 30 cm, and 40 cm. As well as variations in the flow rate of acid mine water 1 L / hour and 2 L / hour. The highest removal efficiency was achieved at a flow rate of 1 L/hour with an activated carbon thickness of 40 cm, which was 99.38% Fe and 95.28% Mn. Statistical analysis showed that variations in thickness and flow rate only had a significant effect on Fe removal efficiency. Fe breakthrough at 1 L/h occurred at the 18th hour for 20 cm thickness, 30 cm and 40 cm thickness have not reached breakthrough conditions. For Mn breakthrough occurred at the 3rd hour (20 cm), 6th hour (30 cm and 40 cm). At 2 liters/day
