*Note 1: Soda ash (sodium carbonate) systems and sodium hydroxide injection systems will raise the pH based on the
amount of the chemical that is being injected. The higher the rate, and the greater the quantity of the soda ash or sodium
hydroxide is being added to the water, the higher the pH will become. If too much of the chemicals are added, particularly
sodium hydroxide, the pH level may raise to high, to dangerous levels.
*Note 2: depends on untreated water temperature, alkalinity, total dissolved solids and hardness
*Note 3: depends on rate of feed
*Note 4: Question: How much harder in calcium hardness will my water be after the neutralizer? Will I notice a difference? Answer: The neutralizer works by adding calcium carbonate (also called ‘water hardness’) to the water. This raises the pH
of the water from an acidic condition (less than 7.0, which is neutral pH) to neutral or greater than neutral. Depending on
your pH to begin with, and how much hardness and alkalinity is in the untreated water, the water hardness will typically raise
from 1 to 4 grains per gallon, or 17 to around 70 milligrams per liter of water. If there is less than 5.5 and you have very low
hardness already (less than 50 mg/L) a water softener may be required after the neutralizer. This can always be added later,
should a water softener be desired.
Note 5: You can add soda ash to your chlorine feed pump system to raise the pH as well. Chlorine is already on the basic
side (alkaline) so adding soda ash will raise it even higher. This should not be done if chlorine injection is for bacteria
control!
