Removal of Metal Iron from Groundwater Using Aceh Natural Zeolite and Membrane Filtration

The adsorption and the ultrafiltration processes were combined for removal of Fe2+ in water sample solution. Aceh natural zeolite used as an adsorbent, and three kind of ultrafiltration membranes (M10K, M30K, and MPVP) were used in this study. The concentration of Fe2+ in the product of adsorption and ultrafiltration is about 0.254 mg/L. This value is below the permissible limit of ferrous metal (0.3 mg/L) in drinking water. The combination of adsorption and ultrafiltration can be used as an alternative treatment of excess iron content in groundwater.
