hardness, cannot be removed by simple adjustment of pH. Therefore, soda ash (sodium carbonate) must be externally added to precipitate this remaining calcium. Magnesium is removed due to the precipitation of magnesium hydroxide. In the lime soda ash process, lime is added to raise the pH while sodium carbonate is added to provide a source of

Soda ash (sodium carbonate) is a powder that is mixed with water and injected into the water pipe before the pressure tank to raise the pH of water. By dissolving 2 to 3 lbs of soda per gallon of water and injecting this solution at a rate of 100 ppm to 200 ppm, the pH will rise to the — range, assuming a typical well water flow rate of ...
