After RO filtration, the water passes through a UV sterilization lamp to eliminate bacteria, viruses, and other microorganisms. Further treatment is provided through Nano filtration, Mineral, Alkaline, and Copper cartridges, which enhance the water by adding essential minerals, balancing pH levels, improving taste, and providing additional antimicrobial benefits. Wastewater generated during the RO process is discharged separately, while the treated water is collected as pure drinking water.

The proposed system provides an eco-friendly, energy-efficient, and cost-effective method for water purification and desalination, making it suitable for rural, coastal, and off-grid areas where access to clean drinking water is limited. By combining solar power with multiple purification technologies, the system ensures safe, healthy, and sustainable water supply.

Objectives:

1. To develop a solar-powered water purification and desalination system.
2. To remove dissolved salts and impurities from water using Reverse Osmosis (RO) technology.
3. To disinfect water using UV treatment and eliminate harmful microorganisms.
4. To enhance water quality using mineral, alkaline, nano, and copper filtration stages.
5. To provide safe, clean, and healthy drinking water for domestic use.
6. To utilize renewable solar energy and reduce dependence on conventional electricity.
7. To reduce water purification costs and improve energy efficiency.
8. To provide a reliable drinking water solution for remote and rural areas.
9. To promote sustainable water management and environmental conservation.
