Mine Water Treatment Plant Design

project overview

Integrated Sustainability was contracted to conduct feasibility engineering and cost estimation for a 3,000 m3/d mine water treatment plant. The design included advanced treatment technologies and explored preconditioning options.

project deliverables

• Developed a high-density sludge treatment system to reduce dissolved metals, including copper, cadmium, and iron, through optimized pH control and sludge recirculation.
• Designed a ferric co-precipitation process to achieve arsenic removal in compliance with regulatory discharge criteria.
• Engineered a full-scale moving bed biofilm reactor (MBBR) system for ammonia treatment, designed to accommodate peak flows of 3,000 m³/d.
• Integrated process tanks, clarification systems, and filter press equipment for sludge dewatering into the overall treatment process design.
• Conducted feasibility-level engineering across civil, mechanical, electrical, and process disciplines.
• Prepared Class 4 cost estimates aligned with feasibility-stage design, including projected capital savings through optimization of the ammonia treatment system.
• Evaluated influent water characteristics to assess opportunities for process preconditioning and treatment optimization.
