Providing safer drinking water to those in need may be a little easier. According to Penn State researchers, a new desalination technique is able to remove salt from water using less energy than previous methods.

"Globally, there is reduced access to fresh water," said Bruce Logan, Evan Pugh University Professor in Engineering and the Stan and Flora Kappe Professor of Environmental Engineering. "More and more, the waters that are being used are impaired, either due to salt or other contaminants, so we are seeing an increasing need to rely on less optimal water sources."

To combat this problem, Logan, and colleagues Christopher Gorski, assistant professor of environmental engineering, and Taeyoung Kim, post-doctoral scholar in environmental engineering, have come up with a desalination method called battery electrode deionization (BDI). BDI improves upon standard capacitive deionization (CDI) techniques by eliminating the regeneration stage and lowering the voltage required to complete the process.
