pH control in swimming pools with carbon dioxide
Evaluated Alternative
Summary
A clean and safe alternative to harsh solvents for pH correction.
Description
Historically, pH control has been carried out with harsh solvents (mineral acids) that can be dangerous to handle. Carbon dioxide offers a clean and safe alternative for pH correction. When dissolved in water, CO2 reacts to form carbonic acid, a weak acid capable of safely reducing the pH to the desired value. Recuperated from natural processes, it is also an environmentally friendly solution.
Benefits of Using CO2 as a pH-reducing Agent :
- Chlorine gas fumes removal
- Less maintenance costs
- Precise pH control
- Reduced chloramines generation
Possible replacement to
Chlorine-based disinfectants, such as NaClO
