Less than 1 percent of Earth’s water is drinkable. Removing salt and other minerals from our biggest available source of water—seawater—may help satisfy a growing global population thirsty f... Read more
Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water — and much of that area is not served by an... Read more
Computer simulations indicate graphene desalination membranes could vastly outperform existing reverse-osmosis systems The earth harbors about 1.4 billion cubic kilometers of water. Unfortun... Read more
SINGAPORE’S average annual rainfall is more than double that of notoriously soggy Britain, so the casual observer might be surprised to learn that the place has a shortage of drinking water.... Read more
In the June 2011 issue of Physics World, Jason Reese, Weir Professor of Thermodynamics and Fluid Mechanics at the University of Strathclyde, describes the role that carbon nanotubes (CNTs) c... Read more
When it comes to desalinating salt water, two of the main options are thermal distillation and reverse osmosis. Thermal distillation involves boiling the water and collecting the resulting f... Read more
A process that cleans wastewater and generates electricity can also remove 90 percent of salt from brackish water or seawater. Read more
