SASKATOON INSTALLS SYSTEM | PROCESS REMOVES NUTRIENTS AND PRODUCES A GRANULAR FERTILIZER

A Vancouver company that recovers phosphorus, nitrogen and other crop nutrients from municipal wastewater is hoping its deal with the City of Saskatoon is the first of many similar agreements to be signed in Western Canada.

Ostara Nutrient Recovery Technologies recently installed a $4.5 million nutrient recovery system in Saskatoon’s wastewater treatment plant.

The system is expected to recover about 300 tonnes of phosphorus-rich granular fertilizer each year from the city’s wastewater.

The nutrient recovery system is Ostara’s fifth in North America and its first in Canada.

Ostara chief executive officer F. Phillip Abrary said interest in nutrient recovery systems is increasing in Western Canada and throughout North America as concerns about water quality and nutrient loading grows.

“There’s a big opportunity all the way (across) Western Canada…,” Abrary said.
