FABRICATION OF REVERSE OSMOSIS WATER PURIFIER USING SOLAR POWER

Abstract

Access to clean and safe drinking water is a fundamental necessity, yet many rural and remote areas continue to face challenges due to contaminated water sources and unreliable electricity supply. Conventional water purification systems depend on grid power, limiting their effectiveness in off-grid regions. To overcome these challenges, this project presents the design, development, and successful implementation of a Solar Powered Water Purifier that operates entirely on renewable solar energy. The developed system integrates a solar power generation unit with a multi-stage water purification process. The solar subsystem consists of a photovoltaic solar panel, charge controller, and optional battery backup to supply electrical energy to the DC water pump and purification unit. The water purification subsystem includes a sediment filter for removing suspended particles, an activated carbon filter for eliminating Odor and chlorine, and an RO membrane for removing dissolved salts, harmful microorganisms, and other impurities. The purified water is stored in a hygienic storage tank for safe consumption. Proper power calculations were performed to determine the total load requirement, and an appropriate solar panel capacity was selected to ensure efficient system operation. A durable supporting frame was fabricated to mount all components securely. Electrical wiring was completed with necessary safety protections, including fuse and proper insulation. The system was assembled and integrated successfully.
