Water is one of the basic life support systems. Both emerging and developing economies world-wide, face a turbulent water future with respect to quantity and quality. There are areas which face perennial water shortage. A significant number of rural and remote locations are suffering from excess salinity, fluoride, iron, arsenic, heavy metals and microbial contaminations of ground water. The contaminants lead to widespread water-borne diseases. Growing development in cities and industrial sector are putting great stress on the aquatic environment. Newer contaminants are reported in ground water time to time. Challenges faced by the emerging and developing economies are unique in many respects.
There is need for integrated approach to deal with water issues. It involves seawater desalination, brackish water desalination, wastewater treatment including recycle and reuse, water purification for removal of contaminants from raw water such as micro-organisms, fluoride, iron, arsenic as well as water conservation on case to case basis.
Membrane technologies play an important role in desalination and water purification. There is need to address the local challenges. Potential of low carbon desalination, water purification and sanitation is very promising particularly in addressing the issue of adverse impact of climate change. The water market is huge and there is great potential. There are challenges and opportunities. There is need for development of low carbon desalination and water purification technologies particularly for rural and remote areas. IITGN has potential to establish itself as ‘Centre of Excellence in Water Technologies’.Discipline/Coordinating Entity: Chemical Engineering
