Sun-powered desalination for villages in India

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 electric grid that could run conventional ...

New insights into 'switchable water' have implications for water purification and desalination

(Phys.org) —Water is rarely pure; instead, it often contains dissolved ions or is mixed with other liquids. Scientists can change the composition of water by separating its mixtures, which is most commonly performed by ...

Cleaning 'produced water' from natural gas wells, potential for improved desalination plants for developing countries

Increased natural gas production is seen as a crucial step away from the greenhouse gas emissions of coal plants and toward U.S. energy independence. But natural gas wells have problems: Large volumes of deep water, often ...

A more affordable, accessible material for seawater desalination

There are vast quantities of seawater available; drinking water, on the other hand, is in scarce supply. Desalination plants can convert seawater to drinking water. Yet these plants require pipelines made of a special kind ...
