Solar Powered Water Purification System Using Integrated UV Disinfection

Abstract – Water scarcity is a pressing global issue, especially in areas with limited freshwater but abundant seawater. Conventional desalination methods often require substantial energy and infrastructure, making them unsuitable for remote or low-resource regions. This project introduces a Solar-Powered Water Purification System that transforms seawater into safe drinking water using renewable energy. The system combines reverse osmosis for salt removal with UV disinfection to eliminate harmful microorganisms, ensuring high water quality. Power solar photovoltaic (PV) panels, the design focuses on sustainability, low energy use, and ease of maintenance. The methodology involves selecting efficient solar components, designing the desalination unit, and integrating UV treatment. A working prototype is developed to test performance, durability, and water output. To improve long-term operation, the system incorporates energy storage and explores self-cleaning UV technologies. This innovative solution addresses challenges like high desalination costs, microbial safety, and limited access to clean water. By offering a practical, energy-efficient, and scalable approach, the project supports sustainable water access and environmental conservation, contributing to global efforts in managing the water crisis.
