Abstract
Improving the quality of groundwater contaminated with heavy metals and dissolved organic matter is a priority in water resource management to ensure the availability of clean water. This study evaluates the combination of aeration and adsorption methods using a diffuser aerator and siwalan shell activated carbon. The aeration method was conducted with variations in detention time to increase dissolved oxygen (DO) levels and reduce concentrations of Fe, Mn, Total Dissolved Solids (TDS), and Total Organic Carbon (TOC). The adsorption process was carried out with variations in media height and flow rate to optimize contaminant removal. The results showed that aeration increased DO to 5.4 mg/L within 60 minutes and reduced Fe and Mn levels by 53.6% and 7.7%, respectively. Adsorption with a media height of 45 cm and a flow rate of 10 L/h achieved reductions in Fe, Mn, TDS, and TOC concentrations by 63.19%, 99.25%, 15.51%, and 17.61%, respectively. SEM-EDX characterization revealed that siwalan shell activated carbon is dominated by carbon, oxygen, sodium, and calcium elements, supporting the adsorption mechanism through ionic bonding and electrostatic interactions. This study demonstrates that siwalan shell activated carbon is effective, environmentally friendly, and has the potential to be developed as a local adsorbent material for sustainable groundwater treatment systems.
