Efficient solar desalination unit uses titanium-coated diaper material

Desalination is an important technology that may help expand the world’s supply of drinking water. Now, engineers in China have demonstrated a new, relatively simple design for a solar still with a high efficiency and low cost.Continue ReadingCategory:… Continue reading Efficient solar desalination unit uses titanium-coated diaper material

New coating could make desalination tech more efficient and less toxic

While reverse osmosis is a relatively energy-efficient form of seawater desalination, it is nonetheless made less efficient by a problem known as biofouling. A new membrane coating, however, could address biofouling like never before.Continue ReadingCa… Continue reading New coating could make desalination tech more efficient and less toxic

Corrosion-resistant desalination device can handle super-salty water

Desalination systems play an important role in improving access to fresh water, but some types of the natural resource are too salty for current solutions to handle. Such hypersaline water can have salt content as much as 10 times greater than seawater… Continue reading Corrosion-resistant desalination device can handle super-salty water

Highly efficient process makes seawater drinkable in 30 minutes

Access to clean, safe drinking water is a necessity that’s worryingly not being met in many parts of the world. A new study has used a material called a metal-organic framework (MOF) to filter pollutants out of seawater, generating large amounts of fre… Continue reading Highly efficient process makes seawater drinkable in 30 minutes

Solar-powered desalination systems could bring water to disaster zones

It’s one of life’s most frustrating ironies that Earth’s surface is over 70 percent water, but most of that is undrinkable. Desalination is an important technology that may help unlock more drinking water, and now two independent teams have developed n… Continue reading Solar-powered desalination systems could bring water to disaster zones

Wooden filtration membrane promises efficient and more sustainable water desalination

Water desalination technologies play a vital role in converting saltwater into freshwater in parts of the world where access to the latter is lacking, but there is plenty of room for improvement. One opportunity for this lies in the materials… Continue reading Wooden filtration membrane promises efficient and more sustainable water desalination

Hydrophilic disc uses solar power to separate salt from water

Current approaches to water desalination are tremendously expensive and energy-intensive, so the search is very much on for new technologies that can get the job done more efficiently. Scientists in Melbourne have put forward one rather promi… Continue reading Hydrophilic disc uses solar power to separate salt from water

Graphene Desalinates Sea Water

Even though the majority of the Earth is covered in water, a surprising number of people around the world don’t have easy access to clean drinking water. The oceans of course are full of salt, and it is difficult to filter that salt out. Researchers at the University of Manchester …read more

Desalination Produces 50 Percent More Toxic Brine Than Previously Thought

The world’s desalination plants, which use energy intensive processes to remove salt from water, produce enough toxic brine each year to cover all of Florida under a foot of water. Continue reading Desalination Produces 50 Percent More Toxic Brine Than Previously Thought
