5. Changes in calcium-carbon characteristics

The use of treatments designed to alter the calcium and carbonate characteristics of water is generally dictated by the water’s aggressive or scale-forming nature.

These treatments are primarily:

• the neutralization of the ${\text{CO}}_2$ aggressive (prevents corrosion in distribution networks and certain circuits);

• water softening treatments (complete or partial removal of $\text{TH}$ ) and/or decarbonation (removal of the $\text{TAC}$...
