IIT Guwahati Develops Low-Cost Water Purifier for Fluoride and Iron Removal

IIT Guwahati researchers have created a low-cost, energy-efficient water treatment system that removes fluoride and iron from groundwater. Capable of treating 20,000 litres daily at just ₹20 per 1,000 litres, it removes up to 94% iron and 89% fluoride. The 4-step process includes aeration, electrocoagulation, flocculation, and filtration. Future plans include solar power use and smart automation for remote areas.
