pH adjustment
Correction (adjustment) of pH.
Principle.
The pH adjustment of water is to inject reactants in order to decrease the pH (per acidification) or raise the pH (per alkalinization or basifying) to a pH desired value.
The chemical action of the products thus give, as a function of pH of the water present and the desired pH :

Note: Calcium (calcium hardness) does not change.

To do this, six reagents are provided:

Notes alkalinization.
Two cases may occur:
