IIT Jodhpur develops clay-based solution to purify water

With a view to solve the problem of contaminated water, IIT Jodhpur has come up with a low-cost and environment friendly solution for treating contaminated water. Rakesh Kumar Sharma, Associate Professor in Department of Chemistry, of IIT Jodhpur has recently developed Rajasthani clay-based photocatalytic water purification technology, along with his Students and Staff Member colleagues. In India, underground water is a major source for drinking and agricultural purpose. Often, these water supplies are polluted with harmful substances, such as dyes, fluoride rich chemicals and other industrial discharges. Also, water contamination has emerged as a major societal problem with respect to their ill-impact on health and economic well-being of the people in the affected areas. The treatment of such contaminated water is not only expensive but also practically unviable. This technology can be used under sunlight using Rajasthani clay to treat textile contaminated water, a major problem in western Rajasthan; this technology can purify polluted water quickly and make it safe at very low cost.
Currently, IIT Jodhpur is aiming to prepare a prototype to provide technical solution for water purification to rural and remote communities, using mobile van equipped equipment with photocatalytic water purification systems, and considering the licensing of this technology to businesses.
