Breakthrough in Arid Egypt For Making Salty Sea Water Drinkable

In a country suffering from a severe water shortage, a new innovation could turn salty seawater into a ready supply for drinking and irrigation.

The new filter invented by Egyptian scientists promises to make saltwater drinkable using just half the energy relied upon by current methods.

It was created using a sheet-like membrane, made from five simple ingredients available throughout North Africa, which allows a process called “pervaporation,” letting water vapor pass through the membrane while trapping the impurities.

The salt in the water bonds with the membrane, allowing the vapor to be harvested as fresh water for drinking or irrigation.
