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.

Ordering Notes:
- Calcite Filters are available with USA or European style plugs and voltages. Please add the appropriate voltage code to the end of the model when ordering.
- 120V AC/60Hz with USA cord = US
- Example: W-N744ET-US
- European 220V AC = EU (EU plug is removable to convert into universal 220v cord)
- 5 gpm per sq. ft. of media is the best design condition for filtration. For relatively clean water, you may go up to design criteria of 15 gpm per sq. ft. Backwash flow rate based on 25 psi pressure drop.
- Skid mounting, control panel and custom sizes and configurations are available upon request. AMI Calcite Filters are offered standard with new state of the art electronic programmable valves, but may be ordered with electromechanical Fleck valve heads upon request.
