Groundwater is the largest source of water that contains iron (Fe) and manganese (Mn). One method that can be used to decrease iron content (Fe) and manganese (Mn) is aeration using tray aerator. Tray aerators can increase the air contact time with water by letting the water flow down on a cross section. This study aims to determine the ability of tray aerator in removing iron (Fe) and manganes…
