Process selection, process engineering, and construction management for a mine water treatment plant for metals removal, and advanced polishing for selenium removal

Project Execution

Highlights:

  • Treatment to remove dissolved metals (Al, As, Cd, Cu, Zn, Fe) and selenium at multiple oxidation states to meet discharge criteria for the receiving environment.
  • Plant design capacity = 390 m3/h.
  • Major Process Equipment:
    • High Density Sludge Metals Removal Treatment
    • Ion Exchange Unit + Electro Reduction Unit
    • Reagent Dosing
    • Process Tanks
    • Clarification Unit & Multi Media Filtration
    • Filter Press (Sludge Dewatering)
  • Process selection, engineering, 3 D plant modelling, and advanced thermodynamic aqueous chemistry modelling with multivalent ion separation software.
  • Analysis of multiple feed water sources resulting in a phased treatment approach due to expected mine water acidification during closure and post closure.
  • Provided NI 43 101 Qualified Person signoff on feasibility study.
  • Delivered with BQE Water ( BQE ion exchange / electro reduction technology developer).

Source Water Treatment & Pipeline Study

Changing regulatory requirements surrounding the use of fresh water for Steam Assisted Gravity Drainage (SAGD) heavy oil extraction resulted in the need for this study. Through it, Integrated Sustainability was able to provide a quantitative comparison of the capital, operational and maintenance costs of all feasible water options, while validating the basis of design and the technical feasibility of pipeline transport and on-site water treatment.
