Water pH control with CO2

As an expert in pH control of water with CO2 and pH neutralisation with CO2, ACP runs dozens of installations all over Europe. 

Some specific applications:

  • Treatment of alkaline wastewater resulting from the washing of glass bottles in the beverages industry
  • Regulation of the pH level in swimming pools as well as the pH level before flocculation
  • Reducing e.g. calcium and zinc by means of pH correction with CO2

Advantages of pH control with technical CO2

The main advantages of pH control / pH neutralisation with CO2 are:

  • CO2 is a weak acid (neither toxic nor corrosive)
  • CO2 can perfectly be used to replace strong acids such as sulfuric acid
  • No 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
