Magnetic Water Conditioning - The
Science
Hard Water
Water hardness refers to the amount of minerals, particularly calcium carbonate, dissolved
in the water. When hardened water becomes over saturated with minerals, is
heated, agitated, or is subjected to decreased pressure, the dissolved minerals
precipitate out and attach to our plumbing and hot water appliances.
Hard water minerals can precipitate out of solution anywhere in your plumbing system.
However, heating hard water or decreasing the pressure the water is under, is responsible
for most of the damage caused to hot water heaters and other appliances as well as the
unsightly scale seen on taps, sinks, toilet bowls and shower heads & screens.
Why water is hard
Rain water is naturally soft. However, rain water
subjected to acidic conditions and contact with limestone rock will be the hardest.
Water first forms when water vapour in the air interacts with particulate matter to
form raindrops. As rain falls, it absorbs carbon dioxide and other materials, some of
which cause the water to form a slightly acidic pH. This primes the water droplet with an
extra measure of solvency.
The solvency characteristics of rain water are further enhanced when the water interacts
with polluted air creating acid rain. The more acidity the water is subjected to the lower
the water's pH. Water with a pH below 6.8 is considered acidic.
When water flows through and over areas
consisting chiefly of calcareous and other limestone based rocks, these calcium and
magnesium carbonate surfaces, which normally would not dissolve in water, are affected by
the acidic water that is looking for a buffering agent to counter its acidic
condition.
The flowing, acidic water will dissolve and absorb the calcium carbonate until the water's
pH returns to a more stable acid/ base balance. Thus, surface salts which normally would
not find their way into our water, are trapped and carried as unwilling passengers in the
form of calcium bi-carbonate.
The minerals are carried in the water within protective complexes that keep the minerals
separated from other dissolved minerals and micro contaminants that are also contained in
the water. As the water continues to flow to its final resting point, it dissolves
additional minerals but at a decreasing rate.
This is because the dissolved minerals cause the pH and surface tension of the water
to increase thus decreasing the water's ability to dissolve additional material.
The hardness of water flowing into your house or business depends on the extent of its
exposure to surface and sub-surface rocks and limestone structures and the extent to which
it was subjected to acidic influences.
About 60% of homes are plagued with problematic water hardness.

Lime scale
Minerals dissolved in the water, primarily bicarbonates of calcium and magnesium, remain
within their host complexes under normal conditions. The dissolved particles flow evenly
within the water having no particular tendency to bind together or lose their solubility.
However, when the mineral content of the water becomes over saturated, is heated, or
placed under decreased pressure (as it does, for example, when the water exits the pipe
and flows into your taps, toilets and showers), the water releases gases such as carbon
dioxide that increases the water's pH and allows mineral complexes to become agitated,
break up and the minerals to clump into larger masses.
The clumping effect makes it more difficult for the minerals to remain soluble and the
crystallised mineral precipitates out of solution and attaches to any available nucleation
centre, typically your plumbing walls and fixtures.
What magnetic conditioning does
Magnetic water conditioning is simply the attachment of powerful magnetic devices to the
water pipes of your home or business.
Magnets can be used to treat domestic water supplies as well as commercial and industrial
applications. The process involves installing the magnetic system onto the water pipe
where it comes into your property.
The magnets surrounding the water pipe create a magnetic force field that interacts with
charged molecules in the water that surround suspended colloidal particles such as
calcium, magnesium and silica.
As a result of this interaction, natural repulsion tendencies of these disbursed colloids
are disturbed preventing scale-producing minerals from precipitating out to form scale in
your plumbing and, over time, existing scale in the system is eliminated.
