IIT--Kharagpur and Oxford ​Develop ​Technology for ​Water Treatment

Researchers at Indian Institute of Technology-Kharagpur and University of Oxford have developed a low-cost technology to treat water contaminated with arsenic.

In this new method, water is chemically treated by activating naturally available laterite that acts as an adsorbent to filter arsenic. The department of science & technology as well as the West Bengal public health engineering department and West Bengal arsenic task force have already accepted the technology. 

Arsenic contamination of ground water is a major health hazard and West Bengal is one of the Indian states affected by this problem.“ The low cost of the filter makes it ideal for the socio-economic conditions of our country. Filtered water can be produced at just 2 paise per litre,” said Sirshendu De, a professor at the department of chemical engineering, IIT-Kharagpur. 

The collaborative research with University of Oxford includes efficient design of large-scale filters based on strong foundation of modelling from first principles. The Oxford team worked on the mathematical modelling techniques to predict the extent of arsenic contamination through the filtration bed and performance of the adsorption medium. 

By combining mathematics with experiments and field data, the team helped predict how the filter performs in large scale, enabling the commercial deployment of these new heavy-metal filtration technologies.
