Clean and affordable water to meet basic human needs has become a majestic challenge to the current century. All around the world, water supply thrash about to keep up with the rapid demand growth, which is aggravated by climate change at global level, population growth and deterioration of water reservoirs. The need for technological innovation to enable water management integration could not be overstated. In past the remedial technologies used for the waste water treatment were chemical precipitation, chemical coagulation, ion exchange etc. But with the advent of technology they are now being replaced by nanotechnology, as it is lucrative method. Nanotechnology carries immense potential in advanced treatment of water and wastewater to increase treatment efficiency as well as to augment water supply during safe use of irregular water sources. These technological progresses have been traced to the physicochemical properties of nanomaterials, the current review article outlines the limitations and opportunities to discuss further benefits on these unique technological advancements for sustainable water and waste water management.
