Evaluation of the effectiveness of Fe3O4 nanoparticles and sand filtration in removal of TDS, SO4, Cl and HCO3 in Aquifer Bahr Al-Najaf
This study was conducted to evaluate the efficacy of Fe3O4 nanoparticles and sand filter in removing total dissolved solids (TDS), Sulfate (SO4), chloride (Cl), (HCO3) in Bahr al-Najaf aquifer. Groundwater Samples were collected from a well in Bahr al-Najaf region to analyze some physical and chemical parameters (includes total dissolved solids, sulfates, chloride and bicarbonate). The results showed nano iron oxide has the following removal efficiency: 76.3 for TDS, 64% for SO4, 87.5% for HCO3 and 82.8% for Cl. However, the sand filter has much lower removal rates compared to nano iron oxide, with 37%, 53%, 50% and 35% for the mentioned pollutants, respectively.
