Backwashing Filter Introduction
The pH Balancing filter with calcite is designed to raise the pH of the water in cases of
low pH (acid water conditions). It also adds some calcium hardness back to the water,
and only requires periodic backwashing. Many areas of the country have water with
low pH. A low pH means that the water is acidic and can corrode copper pipes and
cause blue-green stains on plumbing fixtures in your home. The pH Balancing system is
designed to neutralize the acid balance of your water supply. It does this by using calcite
which is crushed and screened white marble limestone. If your pH is below 5.8, then we
recommend a blend of calcite and magnesium oxide. Calcite and magnesium oxide will
increase hardness in the water and a water softener may become necessary after the
neutralizing filter.
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 over correct 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 the pH, water chemistry and service flow, the calcite /
magnesium oxide bed will have to be periodically replenished as the calcite is depleted.
The pH Balancing filter is a fully automatic backwashing filtration system. It uses all NSF
and FDA approved components, including the calcite. The electronic computer control
redistributes the media bed to prevent channeling.
