Inactivation of Heterotrophic Bacteria in Well Water Using ZVI, TiO2 and ZnO Nanoparticles
Background & Aims of the Study: The heterotrophic bacteria are widely used as a water microbial pollution index for drinking water. The aim of this study was to investigate the effect of metallic nanoparticles such as Zero Valent Iron (ZVI), Titanium dioxide (TiO2) and Zinc oxide (ZnO) on Hetero...
