Upflow calcite contactors
of constant height
Our research is our strength®
Since 2004, we manufacture custom calcite contactors using the most efficient design for the remineralisation of soft or desalinated waters, based on our internal research and development.
Process benefits:
- Upflow to avoid underdrain clogging.
- Internal upper silo for 30 days autonomy.
- Constant calcite feeding for continuous operation without back-washing.
- Constant calcite height for constant water quality.
- High process efficiency ≥96%.
Operational benefits:
- Low operational cost.
- Very low or no energy consumption.
- Consistent performance over the years.
- Minimal and ease of maintenance.
- Low or no automation.
Solutions for small and large-scale projects
Wide range of options to meet different requirements from 20 m³/d upwards:
- Vertical tanks in FRP, PP or SS316.
- Horizontal tanks in FRP.
- Rectangular concrete cells.
- Containerised FRP tanks.
