In water stressed areas, drinking water is sometimes produced from sea water through processes such as reverse osmosis. These processes remove minerals that lead to demineralised water, which is not suitable for drinking. Remineralisation can be achieved through the injection of minerals into the drinking water network with the help of CO₂.
Where drinking water is extracted from the ground, mineral content is not always optimal for human consumption or can be unsuitable for entering into copper pipe networks where the water's low minerality may corrode piping. CO₂ in combination with calcite helps to correct water hardness and prevent corrosion build-up leading to network damage.
Adding CO₂ to drinking water increases the hardness of the water stream, maintaining an equilibrium between carbonate, bicarbonate and free CO₂ and increasing the water mineralisation and dosage of each reagent.
The Halia® neutralisation system correctly dissolves CO₂ to ensure optimal consumption and equilibrium of the pH after remineralisation is complete.
