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.
