CSCE Nooner – Turning Wastewater Into Fertilizer: Canada’s First Nutrient Recovery Facility

February 15, 2017 @ 12:00 pm - 1:30 pm UTC-6


Saskatoon is home to Canada’s first full scale nutrient recovery facility.  In 2009, the Saskatoon Wastewater Treatment Plant was plagued with struvite formations that were damaging to the operation of the sludge handling facilities. In 2012, the WWTP commissioned Ostara’s innovative nutrient recovery technology that recovers phosphorous removed during treatment for reuse as an environmentally responsible fertilizer. Since opening, over 500 tons of fertilizer product have been recovered for commercial sale by using “Waste Activated Sludge Stripping to Remove Internal Phosphorous”. This presentation details the formation of struvite, and the adverse effects its can have on wastewater treatment plant.  The phosphorous cycle will be discussed from the influent of the wastewater, removal in the activated sludge process, and recovery in the nutrient recovery facility.
