SMART-Water is designed for disaster relief, urban flooding, emergency shelters, remote islands and reefs, rural areas, marine operations, and mining. It treats seawater, high-salinity and heavy-metal-contaminated water, and can harvest water from air when no liquid water source is available. Powered by solar PV and energy storage, it supports off-grid operation, produces up to 150 L/day per unit, and offers trailer-mounted, vehicle-mounted, and fixed deployment for reliable emergency drinking water supply.
