Rainy River Mine

Combined Active and Semi-Passive Water Treatment

Ensero was contracted to design, construct, and commission a cost-effective integrated water treatment system on a tight time frame to support the new Rainy River Mine development. The client was interested in evaluating alternatives to Reverse Osmosis (RO) technology to treat process water containing ammonia, thiocyanate, nitrate, copper, arsenic, selenium, cyanide, and total suspended solids (TSS). Ensero’s treatment design helped the client to save more than 60% in water treatment costs by avoiding the need for RO technology. We successfully met the client’s aggressive development schedule, completing the entire design-build-commissioning project within 12 months.
