The Department of Electronics and Communication Engineering at Shri Madhwa Vadiraja Institute of Technology and Management, Bantakal, Udupi district, has developed ‘Dhyuti Jala Shodhan’ — a solar-powered water purifier system for remote villages to provide an efficient, eco-friendly, and cost-effective solution for clean drinking water. The system uses a photovoltaic panel to convert sunlight into electrical energy, which powers a DC pump while simultaneously charging a battery, ensuring continuous operation even under low sunlight conditions.

It employs a multi-stage filtration process, including sediment filters, activated carbon, and micron filters, to effectively remove impurities, odour, colour, dissolved contaminants, and harmful microorganisms. Designed for low power consumption, portability, and minimal maintenance, the system is ideal for remote areas with limited infrastructure, a release from the college said.

The project is sponsored by the Karnataka State Council for Science and Technology and was done by final-year students Srijan, Sharan Dhondya, Suresh Nayak, and Ujwal U. Nayak under the guidance of Jayashree M. and Shashikala R., assistant professors of the department.
