Calcite Neutralization Filters - Neutralize Acidic or Low pH Waters
Calcite Filters with Automatic Backwash for Neutralizing the pH of Water
Calcite is a naturally occurring calcium carbonate media. One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions. Upon contact with calcite, acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces potential leaching of copper, lead and other metals found in typical plumbing systems. Periodic backwashing will prevent packing, reclassify the bed and maintain high service 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.
Benefits of Calcite Filters for Water Neutralization
- Raises pH of water to a non-corrosive equilibrium
- Advantages of Calcite
- Naturally occurring, inexpensive material
- Low uniformity coefficient for maximum contact
- Slower Reacting for controlled pH correction
- Automatic Backwash Feature Reduces Maintenance, Maintains Filter Efficiency, and Prolongs the Life of the Filtration Media
