Design Specifications
A Naïade unit consists of a solar panel, ultraviolet (UV) light, plastic body, a battery and several filters. The solar panel has a capacity of 75 W, and the UV light inside has a capacity of 20 W. The plastic body has a water storage capacity of 100 L, and the outside of the body has pictograms to depict how to use the unit. The water is cleaned through the use of mechanical filters and UV light. The UV light inactivates bacteria, viruses and worm eggs, while the mechanical filters clean impurities, removing particles both large and microscopic to make the water safe to drink.
Technical Support
Maintenance can be carried out by users and local technicians.
Replacement Components
Replacement components include the filters, UV lamps, and batteries.
Lifecycle
