How do you remove alkalinity from well water?

Alkalinity ,can, be defined as the ability of a water to ,neutralize acid, or to absorb hydrogen ions. It is the sum of all ,acid, neutralizing bases in the water. This ability to maintain the proper pH in the ,wastewater, as it undergoes treatment is the reason ,why, alkalinity is so important to the ,wastewater, industry.

An ,acid,-neutralizing filter utilizes calcite or ground limestone (,calcium carbonate,) for normal pH correction, yet it could likewise incorporate a mix of magnesium oxide and calcite if the pH is low. Since the ,water, ingests these minerals when it goes through the channel, the alkalinity and hardness will raise.
