Mine effluent management with lamella clarifier technology
Problem / Need :
A company in the mines sector is looking to treat effluents containing iridium, iron and sulfate residues. The requirements for this treatment are listed below:
- Flow rates from 1 to 13 m3/h, with a model based on 20 m3/h.
- The coagulation and flocculation process is also available upstream.
- Installation inside a building, away from direct sunlight.
- pH range from 8 to 9.
- Temperature range 5 to 30 degrees.
- Storage reservoir upstream of lamella clarifier.
- Sludge removal by pumping required.
- No or little floating sludge.
Method used / Answer provided :
To solve this technical problem, 1h2o3 suggested the installation of a compact lamella decanter made of robust honeycomb plastic, adapted for installation in a closed environment. This system has been developed to optimise space while guaranteeing effective decanting. Additional ports have been integrated into the structure to enable efficient sludge extraction and recycling, making it easier to manage and keep the system running at top performance.
Results
The process adopted in this system is particularly well-suited to treating and eliminating the metal residues found in effluents.
In practice, it succeeds in reducing the concentration of these metallic substances to a significant level, with an efficiency rate in excess of 95%.
This performance is the result of a combination of precise filtration and chemical treatment techniques, engineered to target and effectively remove metals, greatly improving the quality of treated water while respecting environmental standards.
