Remineralisation Filters Limestone contactors

Limestone contactors are used to neutralise the pH and to add calcium and bicarbonates to acidic waters such as groundwater, rain water or Reverse Osmosis permeate.

If water does not contain any agressive CO2, CO2 gas must be injected prior to filter inlet. Please send us your water analysis for a complete design.
