Humanitarian Relief

Handheld Seawater Desalination Device for Emergency Use and Rapid Response

Access to clean fresh drinking water following a disaster is critical to health and survival. Current relief response measures often rely on transporting massive quantities of bottled water into the affected population or distributing water purification devices or tablets that do not have the ability to rid water of salt.

There is an urgent need for a device that can desalinate seawater into fresh drinking water and can be deployed quickly and at low cost in times of crisis.

No such product exists on the marketplace today.

Global Impact 1 Billion People by 2027

Quite simply, water is a matter of life and death. Our bodies are 60% water. Our cities, our industries and our agriculture all depend on it. Yet, today, 40% of the world’s people are affected by water scarcity; 80% of wastewater is discharged untreated into the environment, and more than 90% of disasters are water-related.
