Low pH-Acid Water Conditions
Calcite. Calcite is a naturally occurring calcium carbonate material that is relatively inexpensive and can be used to neutralize acidic or low pH waters. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. Upon contact with Calcite, acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces the potential leaching of copper, lead and other metals found in typical plumbing systems. Periodic backwashing will prevent packing, reclassify the bed and maintain high services rates. Depending on pH, water chemistry and service flow, the Calcite bed will have to be periodically replenished as the Calcite is depleted.
As the Calcite’s calcium carbonate neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter.
