Overview

• The system uses a four-step process of aeration, electrocoagulation, flocculation and filtration to treat up to 20,000 litres of water per day.
• In 12-week field trials, it consistently removed 94% of iron and 89% of fluoride, meeting Indian safety standards.
• At a cost of Rs.20 per 1,000 litres, the unit requires minimal supervision and has a projected lifespan of 15 years with electrodes replaced every six months.
• A pilot installation has been deployed in Changsari, Assam, in collaboration with the Public Health Engineering Department and Kakati Engineering Pvt. Ltd.
• Researchers are exploring integration of renewable energy sources and hydrogen capture to boost the system’s sustainability.
