The first full-scale nutrient recovery installation in North America became operational in May 2009 at the Clean Water Service's Durham Advanced Wastewater Treatment Plant in Tigard, Oregon. Recovering ammonia and phosphorus from the dewatering side stream as struvite has a positive impact on plant operations. Significantly reducing the phosphorus recycle lowers the phosphorus loading on the plant, stabilizes biological phosphorus removal, reduces the amount of chemicals needed to remove phosphorus, reduces both the dry tonnes of biosolids generated and the phosphorus content of the biosolids, and provides revenue from the sale of the struvite. To increase struvite production and to decrease struvite potential in the digestion system, the Waste Activated Sludge Stripping To Remove Internal Phosphorus (WASSTRIP™) process was implemented full-scale in summer 2011. Results indicate a potential 60% increase in struvite production is achievable.
