The WADI from Helioz is a solar-powered water disinfection system designed to purify water using UV light. It is specifically designed for use in remote or off-grid areas where access to clean drinking water is limited. The WADI system is easy to use, requiring just sunlight to operate. Water is placed in a transparent bottle, and the device uses solar energy to activate UV rays, effectively disinfecting the water by killing harmful microorganisms. This eco-friendly and cost-effective solution is ideal for both emergency situations and everyday use in areas with limited infrastructure.
