Abstract: The objective of this study is to remove iron from groundwater by biological means, using slow filtration (V = 0.2 m/h). This technology was characterised by high efficiency throughout the operating period, estimated at 24 days of removal of iron, turbidity and suspended solids. The respective contents estimated in raw water were 5.46 mg/l of iron, 296 NTU of turbidity and 964 mg/l for suspended solids. The maximum value of the efficiency of the technology used for the removal of iron has been set at 98.26%, 99.97% for turbidity and 98.24% for suspended solids, corresponding to a concentration of 0.089 mg/l of iron, 0.09 NTU of turbidity and 17 mg/l of suspended matter in the produced water.
