Abstract –The growing challenge of freshwater scarcity, particularly in coastal and arid regions, necessitates sustainable and efficient solutions. This project introduces an innovative solar-powered seawater desalination system that leverages Reverse Osmosis (RO) and Ultraviolet (UV) purification to convert seawater into potable water. Unlike conventional desalination methods that rely on fossil fuels, this system harnesses renewable solar energy through photovoltaic (PV) panels, making it both environmentally friendly and cost-effective. The process begins with pre-filtration, which removes large debris and sediments, followed by high-pressure RO filtration, where microscopic membranes separate dissolved salts, heavy metals, and pollutants. To ensure complete sterilization, the purified water is subjected to UV treatment, which eliminates harmful pathogens and ensures compliance with drinking water standards. The purified water is then stored in a tank, making it readily available for distribution. Designed for off-grid communities, disaster relief efforts, and remote coastal regions, this scalable and modular system provides a self sustaining, unfriendly alternative to traditional desalination. By integrating cutting-edge purification technology with sustainable energy, this project paves the way for a resilient and accessible clean water solution for water stressed regions worldwide.
