Turning nitrates into water and air

Engineers at Rice University’s Nanotechnology Enabled Water Treatment (NEWT) Center have found a catalyst the cleans toxic nitrates from drinking water by converting them into air and water.

“Nitrates come mainly from agricultural runoff, which affects farming communities all over the world,” said Rice chemical engineer Michael Wong, the lead scientist on the study. “Nitrates are both an environmental problem and health problem because they’re toxic. There are ion-exchange filters that can remove them from water, but these need to be flushed every few months to reuse them, and when that happens, the flushed water just returns a concentrated dose of nitrates right back into the water supply.”
