Laboratory Scale Bioremediation of the Yamuna Water with Effective Microbes (EM) Technology and Nanotechnology

J.N Shrivastava, Nupur Raghav and Abha Singh

In present study, Yamuna water sample was tested and treated with EM technology (bacterial monocultures) and Nanotechnology (AgNO₃ synthesized bacterial monocultures). After treatment, a sharp reduction was observed in all the physical and chemical parameters in the sample throughout the investigations. The bacterial monocultures treated water sample showed a sharp reduction in BOD i.e. 60-85% and 50-80% in COD while AgNO₃ synthesized bacterial monocultures showed 85-95% reduction in BOD and 25-45% reduction in COD. The study concludes that both the technologies (EM technology and Nanotechnology) were effective in the reduction of water impurities but EM technology was more effective in reducing chemical pollutants to the permissible limits in comparison to the nanotechnology, while nanotechnology reduced biological contaminants more than EM technology.
