IIT Madras chemistry professor gets VinFuture Prize for developing low-cost filter for groundwater

NEW DELHI : Professor Thalappil Pradeep from the chemistry department of the Indian Institute of Technology (IIT) Madras has won the ‘VinFuture Prize’ for developing a low-cost filtration system to remove arsenic and other heavy metals from groundwater. Professor Pradeep received the prize at the award ceremony in Hanoi, Vietnam, on December 20, 2022.

The award won by Pradeep is dedicated to ‘Innovators from Developing Countries’ and the recipients of the prize were selected from 1,000 nominations from 70 countries.

Thanking the awards jury for recognizing this research, Professor Pradeep, Institute Professor, Department of Chemistry, IIT Madras, said, “This recognizes everyone who worked with me, everyone who has been benefited from the work and those who enabled the translation of our work. At the same time, I am aware of the huge gap yet to be bridged to deliver clean water to everyone. I hope that this recognition will help in realizing that dream. I thank my institute which gave me everything. I thank my country, which made me stand up.”

Professor Pradeep discovered affordable and sustainable nanomaterials to produce clean water. The arsenic and other materials removed by these materials do not impact the surrounding environment. This method, employing simple designs, provides a means to purify groundwater at a low cost to reach millions of impacted households. In remote areas, this technology is more advantageous because it does not require electricity.
