Delhi-NCR twins Naina and Nayantara Singh have developed a plant-based water purification system called Aqua Sattva. The innovative system uses okra, fenugreek, and rice husk to target microplastics and PFAS, also known as "forever chemicals." The project began as a school-level research experiment and was later developed and tested at IIT Delhi.
The filtration system consists of sachets containing a polymer derived from okra and fenugreek, and biochar made from rice husk. The estimated cost for a pack of 10 sachets is around Rs 100. The system can remove up to 93% of PFAS from water, according to testing conducted at IIT Delhi. Aqua Sattva offers an affordable, low-cost, and environmentally friendly alternative to conventional water purification systems.
