Water Treatment Technology

The scarcity of pure water is a major challenge faced by the world in the recent times, due to the effects of pollution combined with global climatic change. Nanotechnology is promising in the field of water treatment due to the fact that Nanomaterial’s show environmentally interesting chemical and physical properties like increased durability of materials against mechanical stress or weathering, high specific surface area and chemical reactivity of Nanoparticles and large absorption as well as adsorption capacity. The adaptation of highly advanced Nanotechnology to traditional process engineering offers new opportunities in technological developments for advanced water and wastewater technology processes. a growing number of contaminants like micro pollutants are entering the water bodies. Nanotechnology in three aspects of water treatment namely ground water treatment, waste water treatment and saline water treatment has been studied in terms of their sustainability.
