GRAFTA Nanotech
Case Studies
GRAFTA Nanotech Inc was engaged by a copper mining company, located in south-central British Columbia, to provide a sustainable solution for reducing concentrations of selenium and copper, currently exceeding the regulatory limits from seep waters.
An industrial site releasing process water, which after an oil-water separator contains polyacrylic hydrocarbons (PAHS) as well as phenolics including, but not limited to pentachlorophenol, at concentrations exceeding local discharge by-laws.
The contaminated site is situated partly on private property and partly on public roadways, adjacent to Lake Simcoe, Ontario. The local sandy aquifer had been historically impacted by petroleum hydrocarbon released over time through an underground fuel storage tank on a private property.
GRAFTA Nanotech Inc was engaged by a copper-molybdenum mine, located in south-central British Columbia, to provide a sustainable solution for reducing concentrations of nitrate, currently exceeding the regulatory limits.
A decommissioned open pit copper mine filled with water. The water in the pit requires treatment and discharge annually to treat the contaminants of concern (mainly copper) that enter the pit through runoff from the surrounding waste rock.
