The process of desalination, the filtering of salt from salt water, is surprisingly complicated. Removing impurities from water to leave a drinkable product at the end is often performed at dedicated ...

Here’s a mind-boggling stat: There are more than 326 million trillion gallons of water on Earth. But less than 3% of that water is fresh water. And more than two-thirds of that water is locked up in ...

Water covers 71 percent of the Earth's surface, and yet it can still be a scarce resource. That's because nearly all the Earth's water is held in the oceans, and it's incredibly difficult to purify ...

Researchers in Drexel University’s Environmental Engineering Department are collaborating with American Water to apply a new test that is intended to extend the lifespan of seawater filtering ...

Filtering the salt from seawater can take a lot of energy or specialised engineering. A thin membrane made of porous wood may be able to fix that. In membrane distillation, salty water is pumped ...

Beer lovers might be alarmed to hear that beer can pick up small amounts of arsenic as it's filtered to be sparkly clear. But researchers in Germany reported Sunday that they've found arsenic in ...

Alan Turing is rightly famed for his contributions to computer science. But one of his key concepts—an autonomous system that can generate complex behavior from a few simple rules—also has ...
