Innovative Water Treatment System Revolutionizes Fluoride and Iron Removal in India

Researchers at the Indian Institute of Technology, Guwahati, have unveiled an affordable community-scale water treatment system designed to remove fluoride and iron from groundwater. Capable of processing up to 20,000 liters per day, this innovative system promises a significant impact in regions troubled by high levels of these contaminants.

The system, praised for its affordability, can treat 1,000 liters of water for just Rs 20, making it accessible for communities in need. Professor Mihir Kumar Purkait, from the Department of Chemical Engineering, highlighted the severe health risks posed by excess fluoride, such as skeletal fluorosis, a condition prevalent in states like Rajasthan and Gujarat.

After rigorous testing over 12 weeks, the system achieved 94% iron and 89% fluoride removal, meeting Indian safety standards. Installed successfully in Assam, it operates through electrolysis utilizing materials like aluminum. Future improvements aim to incorporate solar or wind power, smart technologies, and decentralized solutions for enhanced efficiency and wider reach.
