IIT Guwahati develops fluoride removal system that treats 1000 liters of water for Rs 20

IIT Guwahati researchers have developed a cost-effective community-scale water treatment system that efficiently removes fluoride and iron from groundwater, treating up to 20,000 liters daily. The 4-step system, tested for 12 weeks, achieves 94% iron and 89% fluoride removal at Rs. 20 per 1000 liters. A pilot project is successfully installed in Assam.
