<![CDATA[Groundwater is one of the alternative water sources commonly used by the community to meet its clean water needs. However, the presence of Fe in groundwater under conditions exceeding the threshold should be a concern, considering the potential dangers associated with long-term consumption. Therefore, this study was conducted to investigate the application of the electrocoagulation method in reducing the Fe content in groundwater. Additionally, the study will investigate the extent of the effect of adding aeration during the electrocoagulation process, as well as the impact of filtration and sedimentation on the post-electrocoagulation water. This research was conducted using a continuous system with voltage variations of 5, 10, and 15 V. The sampling times were 15, 30, 60, 90, and 120 minutes, with a flow rate of 33.3 ml/min using aluminum plates as electrodes. The results show, for each variable, that the iron concentration is below the specified threshold of 0.3 mg/L and can be reduced by up to 99.61%.]]>
