Bruce Rittmann, who holds a PhD in environmental engineering from Stanford University, was named a 2018 Stockholm Water Prize Laureate for revolutionizing water and wastewater treatment through the development of environmental biotechnology-based processes. His work has led to a new generation of water treatment processes that can effectively extract nutrients from wastewater. In his research, Rittmann has studied how microorganisms can transform organic pollutants to something of value to humans and the environment. He has authored or co-authored more than 650 peer-reviewed scientific papers and has chaired the Program Committee of the Leading Edge Technology Conference of the International Water Association. Rittmann is Regents' Professor of Environmental Engineering and director of the Swette Center for Environmental Biotechnology at ASU's Biodesign Institute. The Phosphorus Forum is an annual conference organized by the Sustainable Phosphorus Alliance, a nonprofit membership organization addressing the complex problem of phosphorus sustainability.
