Exciting change is on the way! Please join us at nsf.gov for the latest news on NSF-funded research. While the NSF Science360 page and daily newsletter have now been retired, there’s much happening at nsf.gov. You’ll find current research news on the homepage and much more to explore throughout the site. Best of all, we’ve begun to build a brand-new website that will bring together news, social media, multimedia and more in a way that offers visitors a rich, rewarding, user-friendly experience.

Want to continue to receive email updates on the latest NSF research news and multimedia content? On September 23rd we’ll begin sending those updates via GovDelivery. If you’d prefer not to receive them, please unsubscribe now from Science360 News and your email address will not be moved into the new system.

Thanks so much for being part of the NSF Science360 News Service community. We hope you’ll stay with us during this transition so that we can continue to share the many ways NSF-funded research is advancing knowledge that transforms our future.

Liquid-gated membrane filtration system improves industrial wastewater purification

Filtering and treating water, both for human consumption and to clean industrial and municipal wastewater, accounts for about 13 percent of all electricity consumed in the U.S. every year and releases about 290 million metric tons of carbon dioxide into the atmosphere annually. New research demonstrates that liquid-gated membranes (LGMs) filter nanoclay particles out of water with twofold higher efficiency, nearly threefold longer time-to-foul and a reduction in the pressure required for filtration over conventional membranes. One of the most common methods of processing water is passing it through a membrane with pores that are sized to filter out particles that are larger than water molecules. However, these membranes are susceptible to “fouling,” or clogging by the very materials they are designed to filter out. This problem necessitates more electricity to force the water through a partially clogged membrane and frequent membrane replacement, both of which increase water treatment costs. The new research into LGMs could lead to a solution that could reduce the cost and electricity consumption of high-impact industrial processes such as oil and gas drilling.
