Ostara to Build Nutrient Recovery Facility at Saskatoon’s Wastewater Treatment Plant
VANCOUVER, BC – September 26, 2011 – Ostara Nutrient Recovery Technologies Inc., a leader in phosphorus management solutions, announced today that The City of Saskatoon has approved the construction of a facility at its H.M. Weir Wastewater Treatment Plant (WWTP) that will recover phosphorus and nitrogen from treated wastewater streams and transform them into a highly pure, slow-release fertilizer called Crystal Green®.
Ostara’s technology provides the City with a cost-effective and environmental solution to removing polluting nutrients from the WWTP’s liquid wastewater stream. In addition to removing nutrients from the facility, the City selected Ostara’s Pearl® Nutrient Recovery Technology to help overcome current operational issues caused by the unintentional build-up of struvite. Struvite is a concrete-like mineral deposit which chokes process equipment, increases operation and maintenance costs and threatens plant reliability.
The unintentional formation of struvite is a common challenge in plants such as the Saskatoon WWTP, which practice biological nutrient removal and anaerobic digestion. Previously, the City has been forced to use chemical dosing to address struvite problems, which is cost-prohibitive.
“Ostara’s nutrient recovery technology provides a cost effective and environmentally friendly alternative that will immediately solve Saskatoon’s wastewater treatment plant’s struvite challenges,” said Phillip Abrary, President and CEO (2005-2017) of Ostara.
In July 2010, The City of Saskatoon WWTP commissioned Stantec to prepare an independent struvite mitigation study in coordination with City staff. “The Ostara technology was selected through a cost-benefit analysis and we recommended Ostara’s Pearl technology as the most beneficial solution to Saskatoon’s struvite problem, both in terms of cost-effectiveness and plant reliability,” said Ryan Roberts, of Stantec Consulting Ltd.
Saskatoon’s new nutrient recovery facility will be the first Canadian site to feature Ostara’s newly-designed Pearl 2000, which has the capacity to produce 730 metric tonnes of Crystal Green fertilizer every year. It will also be Ostara’s first commercial implementation of the WASSTRIP® process, which is an ideal complement to the company’s Pearl nutrient recovery technology in plants that are using biological phosphorus removal. The WASSTRIP process was developed in partnership with Clean Water Services, to enhance the efficacy of the Pearl process and control struvite scale formations throughout the sludge treatment stream.
“Ostara’s nutrient recovery technology will integrate directly into Saskatoon’s treatment system, process the sludge processing liquids, and recover a premium-quality, environmentally friendly fertilizer that will generate revenue for the City,” said Abrary.
Ostara will begin construction of the facility immediately and it is expected to be operational in early spring 2012.
