A functional dialysis membrane has been fabricated from a sheet of graphene -- a single layer of carbon atoms, linked end to end in hexagonal configuration like that of chicken wire. The graphene ...

A team of Korean researchers have made a membrane that can turn saltwater into freshwater in minutes. The membrane rejected 99.99% of salt over the course of one month of use, providing a promising ...

The antimicrobial triclosan is widely used in personal hygiene products, textiles and plastics, but when it enters the environment via wastewater, it poses a significant threat to aquatic organisms.

Many people around the world take clean and abundant drinking water for granted. We turn on a faucet and all the water we want is there. In some parts of the world access to drinkable water is very ...

A "straight out of science fiction" liquid membrane developed by a team of Penn State mechanical engineers acts as a "reverse filter" that lets large objects through while blocking small ones. The ...

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 ...
