Background & objectives: In recent years, iron nanoparticles have been successfully used to remove water pollutants. Fecal coliform is one of the parameters that reduces water quality and its removal is essential. The aim of the present study is using nanoscale zerovalent iron particles to enhance the usual sand filters in removal of fecal coliform of groundwater in Ilam city. Methods: Water s...

Nanoscale zero-value iron (nZVI) has a high specific surface area and significant abilities to reduce contaminants. In this study, the removal of color COD from real textile wastewater was studied by nZVI particles. A series experiments were conducted evaluate effect operational parameters such as solution pH, dosage temperature on removal. The results showed that removals mainly depend pH. eff...
