H2-Oh Yes! IIT Guwahati Unveils Game-Changer for Safe Groundwater

In a breakthrough for rural and underprivileged communities, researchers at the Indian Institute of Technology Guwahati (IITG) have devised a low-cost, community-scale water treatment system that removes excessive amounts of fluoride and iron from groundwater—just for ₹20 per 1,000 liters.
 
The Innovation at a Glance
  • The system processes 20,000 liters of contaminated water daily and is therefore ideal for small towns and villages.
  • It removes 94% iron and 89% fluoride, lowering the levels to safe levels according to Indian standards.
  • The technology conserves energy, requires a minimal level of supervision, and lasts for 15 years with electrode replacement needed only after every six months.
How It Works: A 4-Step Purification Process
  • Aeration: Oxygen is added to the water to help strip the dissolved iron.
  • Electrocoagulation: A low voltage electrical current passes through aluminum electrodes, releasing ions that bond with contaminants.
  • Flocculation & Settling: Contaminants clump and settle from the water.
  • Filtration: A coal, sand, and gravel multi-layer filter eliminates last impurities4.
Tested and Trusted
  • The system was tested in real conditions for 12 weeks and yielded clean water reliably.
  • The research has been published in the ACS ES&T Water journal by Prof. Mihir Kumar Purkait and his group from IITG's Department of Chemical Engineering6.
Why It Matters
High fluoride levels in drinking water lead to skeletal fluorosis, a condition characterized by excruciating pain in the bones and joints. Various Indian states, including Rajasthan, Telangana, Andhra Pradesh, Karnataka, Haryana, and Gujarat, are affected by high fluoride levels in groundwater. This technology is an affordable, scalable, and sustainable solution to a erstwhile widespread public health problem.
