IIT Guwahati developed a low-cost, efficient system that removes 99% of arsenic from groundwater using minimal electricity and chemicals, offering a sustainable solution for rural areas.
Researchers at IIT Guwahati have created a low-cost electrocoagulation system that removes up to 99% of arsenic from groundwater in minutes, using a rotating iron anode and stationary cathode to generate iron ions that bind and remove contaminants.
The method requires minimal chemicals, produces less sludge, and operates efficiently in areas with limited infrastructure.
Laboratory tests show it treats 1,000 liters for about Rs.
8–9 using just 0.36 units of electricity, meeting WHO safety standards.
The system is affordable, scalable, and well-suited for rural and semi-urban communities, offering a sustainable alternative to expensive methods like reverse osmosis.
