The course is designed and conceptualised for the scholars to explore the role of nanotechnology in water and environment. Nanotechnology is a platform to design new and novel materials that can be used for various waste water treatment techniques. Some of the techniques based on these nanoscale materials are 1. Adsorption 2. Photocatalysis 3. Membrane systems Course details: Nanotechnology based water treatment methods is an intense course on the fundamentals of the treatment methods. A comprehensive overview of the above methods will be offered in this course that will contribute knowledge to help scholars for critical thinking for research and development in this field.
