Water Treatment Plant – Operations & Maintenance

project overview

Integrated Sustainability was contracted to design a water treatment plant to support a Mines Act Permit Amendment at a gold project. The design addressed complex influent conditions across 3 sources, integrating moving bed bioreactor treatment into ammonia removal. 2 temperature-resilient ammonia removal options were developed to accommodate cold-season flows.

project deliverables

• Completed treatment system design for flows up to 8,700 m³/d of ammonia-impacted water and 32,706 m³/d of metals-impacted water.
• Developed two ammonia treatment configurations designed to maintain treatment performance under low-temperature operating conditions.
• Designed chemical dosing systems for lime, ferric sulphate, and flocculant addition.
• Conducted a hazard and operability (HAZOP) review to identify design risks and incorporate operational improvements into the final design.
• Prepared technical specifications and detailed design packages for major treatment equipment and modular treatment systems.
