Breakthrough graphene membrane can instantly transform sea water into drinkable fresh water

British researchers have developed a graphene oxide sieve designed to remove salt from seawater. The sieve may potentially be highly efficient in straining salt, which could help provide clean drinking water for millions of people who do not have a ready access to it. The researchers will now test the graphene sieve against current desalination membranes. […]

Engineers devise a system that recovers fresh water from power plants

What do you think of an electrical power plant that can also provide an inexpensive source of drinking water? Engineers have come up with a way to recover the water used to cool power plants and purify it for human consumption, an article in Science Direct stated. Nearly 40 percent of the water drawn from freshwater sources […]

Engineers study self-assembling block polymer membranes as an alternative option for water treatment

As water scarcity spreads across the face of the Earth, researchers are scrambling for ways to convert non-traditional sources into potable water. In a Nano Werk article, engineering researchers from two universities reported that self-assembling block polymer membranes could be used as alternative materials in water filtration. The United Nations warned that about 1.9 billion […]

Inspired by nature, new “slippery rough surface” material harvests water out of air

There are many places in the world suffering from water shortages. As such, scientists are constantly looking for ways to alleviate this, trying to come up with possible solutions that can be implemented in the real world today. Now a group of researchers from Penn State and the University of Texas at Dallas (UT Dallas) have […]

Fog harvesting could help alleviate water shortages

As traditional sources of water dry out or grow contaminated with pollution, we’ll need to find new ways to get the water we need. One method is fog harvesting, where you collect moisture from ground-level clouds. A Virginia-based research team has come up with a “fog harp” that collects thrice as much water as earlier fog nets, […]

Clean water graphene breakthrough could allow millions to drink filtered seawater

As drought conditions continue to spread across the globe, from the 2015 drought in California that swept over 90 percent of the state to South American countries like Brazil, and even nations in Africa — it is clear that water is an ever-increasingly precious resource. Even though the Earth is approximately 70 percent water, the […]
