York, Penn.-Ostara Nutrient Recovery Technologies Inc. unveiled another municipal treatment facility that has adopted its process, which recovers phosphorus and ammonia from wastewater to produce a slow-release fertilizer. Ostara joined with the City of York at the Sept. 16 unveiling of the new nutrient recovery facility, which marks the start-up of the second such installation in the pollution-sensitive Chesapeake Bay watershed. The first facility opened at the Hampton Roads sanitation district’s Nansemond plant in May. Under the arrangement with Ostara, the municipalities make no capital investment and pay a monthly treatment fee for designing, building, and financing the operation. Revenues from the sale of Crystal Green fertilizer produced at the plant will be shared with the City of York, thereby further improving the economics of the facility. A pilot study at the York plant in Spring 2008 found that the process recovered more than 90 percent of the phosphorus and 20 percent of the nitrogen.
