Treatment of drinking water with CO2

For over 30 years, ACP has used its expertise in drinking water remineralisation by using CO2 in millions of European homes. When water is too soft, or after inverse osmosis treatment, it can corrode the water pipes. In this case, dissolving limestone in the drinking water with CO2 is one of the best available solutions.

Advantages of drinking water treatment with CO2

The main advantages of the treatment or remineralisation of drinking water with CO2 are:

  • CO2 is a weak acid (it is not toxic, corrosive or dangerous)
  • No risk of leaving a polluting residue in treated water, environmentally friendly
  • Inexpensive equipment, no particular safety rules or training for users
  • As CO2 forms a stable buffer solution, reaction is very easy to control

Realized project: treatment of drinking water for the Metropole Great Nancy (France):

  • About 255.000 in habitants are provided with drinking water by one water treatment factory
  • The Meuse waters are treated 24 hours a day, 7 days a week
  • Unequalled energy efficiency thanks to an evaporator using thermal energy present in the treated water and additional electric evaporators
  • Highly accurate dosing of the gaseous CO2 after evaporation
  • CO2 injection into the water by means of a static mixer
