Effluent Water Selenium Treatment

Black & Veatch partnered with BQE Water through the development and piloting stages to achieve single-digit ppb levels of selenium for complaint discharge. Black & Veatch, in partnership with process subconsultant BQE Water, designed the 4,500-gallons-per-minute Water Treatment Plant 2 facility. Utilizing BQE’s proprietary Selen-IX technology, the project consisted of the construction of a water treatment plant, which will treat dewatering flows from nearby groundwater wells. The plant will also treat water from several smaller side streams at various locations around the mine in the future to meet Arizona discharge permitting requirements.
