Calcite

Calcite is a crushed and screened white marble media, which can inexpensively be used to neutralize acidic or low pH waters to a neutral, less corrosive effluent. 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 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 service rates.  Depending on pH, water chemistry and service flow, the Calcite bed will have to be periodically replenished as the Calcite is depleted.

Technical Information

The AQ-CC Series cartridges are designed to raise the pH of influent waters. These cartridges contain sparingly soluble sacrificial medias that are only acted upon by acidic waters. They will have little effect on neutral or alkaline water.

The AQ-CC Series are flow rate dependent. At flow rates of 0.1 gpm, the CC-01 will neutralize an acidity as low as pH 1.0. Higher pH feeds can utilize higher flow rates. As you approach ph 7 with low flow rates, the CC-01 may tend to over-correct, resulting in a pH above 8.5. If you are concerned about over correction you should choose the CC-10. The AQ-CC-10 is the only acid neutralizing cartridge without overcorrection tendencies. To learn more about the calcium used in the AQ-CC-10 click on Calcite

The AQ-CC Series can be used to neutralize low pH R/O product water and waste streams as well. Since they are sacrificial, the CC Series will add 2-5 ppm of hardness to the water.

This is also an excellent way to reduce the corrosiveness of aggressive low TDS water.
