18,980 m³/day Mine Wastewater Facility Design for a Remote Arctic Location
Project Highlights
Integrated Sustainability designed a facility treating 18,980 m³/day for nitrate, selenium, and dissolved metals removal. Integrated advanced sludge treatment and biological processes for compliance with environmental discharge criteria.
Project Deliverables
- Conducted a comprehensive feasibility study and design for a facility treating 18,980 m³/day of mine water
- Reviewed mine water volumes and geochemistry to define influent conditions, including average selenium at 1.06 mg/L and copper at 0.46 mg/L
- Developed target treatment thresholds of 0.02 mg/L selenium and 0.2 mg/L copper at end-of-pipe, supporting dilution to 0.0046 mg/L
- Screened and compared candidate technologies including iron co-precipitation, adsorption, electrocoagulation, and ion exchange with electro-reduction, favouring modular, scalable configurations
- Outlined integrated flow equalization and source segregation approach to limit peak treatment flow of 18,980 m³/day in summer and 15,860 m³/day outside of summer
