Portage la Prairie tests systems to remove phosphorus, nitrogen from Lake Winnipeg
Portage La Prairie is testing out two systems to take out polluting nutrients from the Lake Winnipeg watershed.
One made by Ostara Nutrient Recovery Technologies recovers up to 85 per cent of the phosphorus and 25 per cent of nitrogen out of the waste water and converts it into non-water-soluble fertilizer.
The other project underway, by Veolia Water, takes out a large percentage of nitrogen. It uses bacteria that digests the nitrogen but does make fertilizer.
Waste water is shown at the Portage la Prairie water treatment plant.
Both projects are being tested for six months at a cost of $200,000.
In 2011, the Manitoba government set guideline to reduce the nutrients of phosphorus and nitrogen to improve water quality.
In abundance, the nutrients cause algae blooms that threaten the health of water systems and pose a health risk to living organisms.
Ostara said the city of Portage La Prairie can sell the fertilizer and use it as way to cover operating costs of the waste water treatment facility.
