Increasing Drinking Water pH
We are planning to use sodium carbonate (Na2CO3) or sodium hydroxide (NaOH) in few drinking water applications to raise the pH:
- Na2CO3 to raise pH from 7. 1 to 8
- NaOH to raise pH from 5 to 7. 5
Do we need to use the food grade sodium carbonate and sodium hydroxide? What are the possible dangers of not using the food grade Na2CO3 and NaOH?
Is there a cheaper method of increasing the drinking water pH if the food grade Na2CO3 and NaOH need to be used?
