Durham, Ore.-Clean Water Services’ advanced treatment facility, which serves six cities in the area and portions of Clackamas and Multnomah counties, has become the second plant in the U.S. to install a new Canadian-developed system that removes phosphorus and other nutrients from the wastewater and recycles the minerals into a granular commercial fertilizer. Although still in the pilot phase, Clean Water is confident enough in the process to show it off recently to the press and other water treatment officials from both Oregon and Washington. The technology was developed by Ostara Nutrient Recovery Technologies Inc. of Vancouver, B.C., to help treatment plants solve environmental problems, increase plant capacity, and reduce maintenance costs, while also creating a revenue-producing byproduct. Hampton Roads Sanitation at Suffolk, Va., recently completed a successful test the Ostara system and evaluating a full-scale installation.
