Reddy terms his science an “accidental discovery.” In the mid-‘90s, Cogema -- a uranium company based in Casper at the time -- was looking for a way to remove selenium from uranium-produced water. The company funded a project for Reddy to remove selenium from uranium-produced water. Reddy used cupric oxide nanoparticles to remove the selenium. Along the way, he discovered his method also removed arsenic from the water. Reddy spent the next seven years trying to understand why.

“Seven years ago, the scientific and engineering community was skeptical,” Reddy says of his discovery. “Now, they are becoming accepting of this new process to filter arsenic and other trace elements from water.”

UW now owns U.S. patents for both the arsenic removal process and for the regeneration of the cupric oxide nanoparticles. Reddy owns four international patents -- in Australia, Japan, Mexico and New Zealand -- for the filtering process.
