Major constituent removal was focused on selenium and metals and was designed to treat water to environmental discharge criteria. The selenium treatment system can perform up to 6,500 m3/day. The metals remove system can perform up to 16,000 m3/day. Integrated Sustainability provided discipline engineering including plant layout optimization and piping design to maximize performance while reducing footprint and cost.
Secondary treatment of HDS plant effluent and TMF supernatant to remove dissolved metals (particularly copper), nitrate, and selenium
Treatment of dissolved metals (Cd, Cu, Fe, Zn), as well as ammonia, from several underground sources prior to discharge into the environment.
Feasibility level engineering design and cost estimating for a mine water treatment plant.
Major constituents for removal included copper, cadmium, iron, arsenic, and ammonia. Plant designed for peak flows of 3,000 m3/day. The design included targeted treatment for arsenic and ammonia. Integrated Sustainability provided full process design, discipline engineering and cost estimating to support the feasibility level design development of the WTP. This includes Influent pre conditioning was investigated to reduce size of ammonia treatment system and reduce estimated plant TIC by $3.4 million.
Prime contractor accountable for project management, construction management, civil earthworks, geomatics, QA/QC, and post construction.
TSS management system utilizing innovative passive flocculation technology for water quality management in surface water event ponds.
provide support to the mine Water Group in support of mine closure planning. Requested deliverables included: Closure planning for decommissioned or soon-to-be decommissioned facilities; Dedicated disposal areas monitoring and evaluation; Bedrock investigation;
Site-wide groundwater monitoring; management plan development; and risk analysis.
Decentralized wastewater treatment plant and disposal design for a large exploration camp in a remote location in the Yukon Territory. Extreme cold temperatures as low as -60°C were expected at the camp. Integrated Sustainability was approached to provide design details, procurement and construction support for the proposed infrastructure to serve the 400 person camp.
Designed modular mobile treatment packages for a remote mine in the Golden Triangle region of BC. Treatment parameters focused on:
metals & arsenic removal, Ammonia removal and
contingency selenium removal.
Process selection, process engineering, and construction management for a mine water treatment plant for metals removal, and advanced polishing for selenium removal.
Integrated Sustainability was commissioned to prepare a hydrogeological assessment in support of reopening a mine that has been in various stats of operation since the 1970’s.
Evaluation of options for a mine to replace base case diesel power with alternatives including solar, wind, biomass, fuel cells, and LNG along with comprehensive energy use modeling for all mine operations.
