How Do You Make A Solar-Powered Water Purifier?
Water purification involves removing waterborne pathogens (disease-carrying organisms) and making any water source not contaminated by dangerous chemicals safe to drink. The sun provides two key elements that destroy pathogens: heat and ultraviolet (UV) light. So a solar-powered water purifier is a cheap, low-tech method of producing small quantities of safe drinking water. Position the black metal surface for fullest exposure to sunlight throughout the day. The surface should be horizontal or with a tilt of less than 15 degrees. Fill the clear, clean plastic bottle with your source water and cap it tightly. Place the bottle on the black surface, which will be exposed to direct sunlight for the whole day. The combination of the sun’s UV light and heat from the black surface with kill any waterborne pathogens.
