The granular solution
Trace metal polishing filtration
BIOHAP granular apatites are used as filter media in filtration systems to provide continuous treatment. They permanently immobilise residual trace metals, helping to meet the most stringent discharge limits.
Their passive operation provides a simple, autonomous solution with no daily handling of chemical reagents.
Key benefits
Designed for industrial applications
- Autonomous operation: minimal operator intervention
- Passive treatment: no handling of chemical reagents
- High retention capacity: a service life of 12 to 18 months
- High selectivity: filter media specifically designed for metal contaminants
- Custom sizing: tailored to your process and treatment objectives
Proven performance
Examples of results
✔ Up to 99% removal
Residual concentrations below 1 µg/L, depending on the contaminants and effluents treated.
✔ Multiple metals removed simultaneously
Copper, zinc, nickel, chromium, cadmium and lead in a single filtration step.
✔ Performance validated on various industrial effluents
Surface treatment, industrial polishing, wire and cable manufacturing, metallurgy, water reuse and more.
✔ Proven filter media for continuous filtration
Results obtained from industrial installations operating for periods of up to a full year.
Practical testing
Validate performance using your own water
Every industrial effluent has a unique composition. A feasibility test performed on a sample of your water allows us to validate apatite performance, estimate the service life of the filter media and size the solution best suited to your installation.
Following the study, a comprehensive report presents the results obtained and our sizing recommendations.
A 5-litre sample is all that is required to begin the study.
