The use of nanoscale zero valent iron (nZVI) as a reactive media in porous media has become a promising technology for contaminants removal from soil and groundwater. Therefore, the main aim of current work is to investigate nitrate removal from water using nZVI in an upflow packed sand column. The effects of one layer, multilayer and different thicknesses of nZVI/sand on nitrate removal were reported in this study. The initial nitrate concentration was 200 mg/L. The distribution of nitrate trapped inside the columns was evaluated by measuring nitrate concentration at various intermediate sampling points along the depth of the column in addition to the column outlet. The results indicated that the best condition to remove nitrate was observed when using single 10-cm high layer of nZVI/sand and more than 97% of influent nitrate was removed.
