Project description
Akvo was hired by ASDR Canada Inc. to manage a project to design and engineer an effluent treatment system for a gold mine with a 1,800-m3/h capacity. The treatment system is made up of a series of reactors that treat copper-cyanide complexes, heavy metals in solution, and nitrates using biological treatment processes, through a settling pond and a sludge management system.
For this project, our mandate was to:
- Review data for the design of the project;
- Plan and supervise project activities and tasks;
- Manage design teams (hydraulics, electrical, mechanical, structural, process, etc.);
- Write reports and technical memos;
- Validate project deliverables;
- Estimate and control project costs;
- Coordinate the activities with the project’s EPC contractor;
- Perform hydraulic gauging of all components in the effluent treatment line;
- Develop a management and storage plan for sludge from the treatment process;
- Lead a feasibility study for the installation of GeotubesTM as a way to dewater sludge;
- Design and present a plan to store sludge within the tailings site, which would save a significant amount of space and enable the sludge to be buried automatically as the site fills up;
- Design site drainage plans, including hydrologic estimates and hydraulic gauging of all crossing structures (pipes, ditches, culverts);
- Assist the client with the treatment system start-up, making adjustments as needed and ensuring that the treatment line’s various components are fully functional.
