remineralization-尊龙凯时平台入口

water remineralisation through the injection of co₂

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.

benefits of using co₂ for water remineralization

self-buffering capacity of the co₂

co₂ has the capacity to balance carbonates, bicarbonates and aqueous co₂ content in water

safe working conditions

automated addition of co₂ for downstream ph control mitigates the need for strong acids

accurate ph control

using co₂ prevents overdosing avoiding the potential of excessive acidification when using strong acids

simple dosage system

the ph regulation system controls the amount of co₂ injection via simple opening and closing of a solenoid valve

simple and reliable mixing device

injecting fine bubbles of co₂ into the water flow, the system ensures full dissolution of the gas into the water

“what about water mineralisation with carbon dioxide?”
the process of water mineralisation or remineralisation is a method of adjusting the minerality of the drinking water to the level recommended for consumer health. the recommended method is a combination of calcium and carbon dioxide injections to reach the necessary minerality level. that process is used where ground waters do not have a sufficiently concentration of minerals or as post treatment in the desalinisation processes.
