Dear Everyone,
I am wondering about the following phenomenon in water softening applications. Even the ion exchange resin manufacturer could not answer my question so your feedback would be greatly appreciated.
The problem:
If you soften the raw water by removing the Ca++ and the Mg++ ions the water's pH shifts to the acidic direction.
What is its reason and is there some calculable correlation between the hardness degree of water and the pH value?
The resin used is a strongly acidic cation resin (SAC) and
it is regenerated by sodium chloride (NaCl). That is why I have difficulties in finding out the reason and correlation to the shift in the pH. I am not a chemical guy so it is hard for me to conclude.
Is there some kind of correlation like 1 gpg decrease in water hardness equals with ... shift in pH???
Thank you very much in advance!
