This study investigates the effectiveness of a filter made from a composite of ore manganese and granular activated Carbon of coconut shells to remove iron and manganese from groundwater. At the first stage of research, ore manganese and activated Carbon were sieved, then the composite was performed in comparison from 20: 60 mess, 20:100 mess, 60:60 mess, to 100:60 mess of ore manganese and activated Carbon. These composites were tested filtration processes to remove iron from groundwater and the effectiveness of iron removal were achieving 94.05% sizing in 100:60 mess. With using particle size of 100 mess manganese and 60 mess of activated carbon coconut, the composite was performed by mass comparison of ore manganese and activated Carbon with combination 25:75, 40:60, 50:50, 40:60, and 75:25. The effectiveness of manganese removal ranges from 74.16 % to 84.5 % and iron removal range from 76.31% to 88.73%, along with the increase in the amount of manganese concentration in the composite. The morphology of manganese was measured by using SEM-EDX, range from diameter 1.06 µm to 671.02 µm, and activated carbon range from 1.3 µm to 55.02 µm. [ABSTRACT FROM AUTHOR] |
