About Water

To understand how our technology works let's first remember some basic facts about water. Water is sometimes
referred to as the "universal solvent". This term is used as water has unique characteristics that allow it to break
the bonds of larger more complex compounds. For example, place a small teaspoon of sugar or salt in a glass of
water, stir vigorously and it will dissolve easily.

Although the water in your home is clear, it is not pure. Being a wonderful solvent, water is very receptive and
dissolves small amounts of the soluble minerals it comes into contact with in nature. Water contains elements
essential for healthy living, including calcium and magnesium.

Hardness in Water

Hardness in water is caused by Calcium Carbonate and Magnesium. Conventional water softeners remove the
essential Calcium and Magnesium macrominerals from the water supply, by replacing them with Sodium. One of the
benefits of the solutions provided by Fluid Dynamics is that they do not remove these essential macrominerals.

Magnesium
While contributing to water hardness, Magnesium does not deposit as scale.

Calcium Carbonate
As we all know H2O can exist in various forms;  Ice, Water and Steam.

Just as water can exist in various forms, so can Calcium Carbonate. The three forms of Calcium Carbonate are:

Calcite
Under certain circumstances ( temperature rise or an increase in pH levels), water is forced to discharge Calcium
Carbonate. The Calcium Carbonate discharged in this way is Calcite, a hard scale. The discharge will accumulate on
the nearest receptive surface, typically metallic.

Aragonite
Aragonite is a form of Calcium Carbonate crystal that, unlike Calcite, prefers to stick to itself and grow attracting
more Calcium.  It remains suspended in water rather than depositing on metal surfaces.

Vaterite
Vaterite is not found in natural water.
Water Treatment

With an unmatched pedigree in the field of hard water scale prevention solutions without the
use of chemicals or electricity, Fluid Dynamics offers their guaranteed green technology for scale
prevention. Our technology has been tested and installed by many of the worlds' leading
companies and establishments. Thousands of units have been installed, many over 30 years old
are still operating perfectly, with no maintenance ever performed.

Scaling caused by hard water can be a major problem, however, it can be prevented without the
use of chemicals or conventional water softeners that can be hazardous and detrimental to the
environment.

Scaling can block nozzles and coat pipework. Deposits can also greatly impact the efficiency of
boilers and heat exchangers substantially increasing energy and maintenance costs.
Water Softening Issues

In an effort to prevent scale formation expensive water softening equipment or chemicals have been widely used. These
methods can cause pollution and are in many instances only partially successful in preventing scale formation.

When untreated hard water is used, it soon becomes necessary to remove scale build up. One method to remove scale
involves the use of hazardous and expensive acid. In some instances mechanical removal with hammers and chisels
becomes necessary.

Since 1973 Fluid Dynamics has offered industrial and, more recently, residential customers totally environmentally
friendly solutions that overcome scaling caused by hard water. Using no salt our products do not require maintenance,
power or chemicals. The water supply is also continual as no back flushing is required. Our product can be easily fitted
to new or existing systems. Following installation, in the majority of cases where prior scale deposition has occurred,
the pipework and equipment will descale. (see how it works below).

Results are guaranteed and we offer a full refund at any time during the first year of operation.

The Fluid Dynamics Solution

Now that we've covered Calcium Carbonate, the two forms it can take in natural water and the events that trigger
scale deposits, we are able to explain the mechanism behind our successful technology.

As water passes through our product it is subjected to a turbulent interaction with a catalytic core made of a special
alloy. The dissimilar metals and the water create a battery effect generating a very small electrical current.

This electric current causes an important change to take place. A percentage of the Calcium Carbonate in the water
comes out of solution and goes into suspension in the form of Aragonite crystals. Although just microscopic in size
these crystals grow attracting more Calcium Carbonate decreasing scale accumulation in previously untreated
systems.

The Aragonite crystal formations remain suspended in the water and pass harmlessly through the system. Changes in
temperature or pH no longer lead to hard scale deposits as the Calcium Carbonate that may have been deposited as
Calcite has previously been converted to Aragonite and is effectively trapped in suspension.

As the process repeats itself, newly created Aragonite crystal formations are continually produced thus preventing
scale deposits. The process also continues to gradually remove any scale that may have accumulated in the past. This
is due to the water being under saturated with dissolved calcium.
Events that cause scaling

Hot Water Scaling

In untreated hard water systems when contact is made with the hot surfaces found in water heaters, humidifiers, kettles,
boilers, heat exchangers etc. scale will be deposited.

Calcium Carbonate is inversely soluble, meaning that as the water temperature rises, the amount of Calcium Carbonate
that can be held in solution decreases. When this occurs in hard water systems the soluble, capacity surplus Calcium
Carbonate that's been displaced by the temperature rise deposits as scale on the nearest receptive surface.

Cold Water Scaling

In untreated hard water systems a rise in pH will also cause scaling. Carbon Dioxide dissolved in water under pressure
takes the form of Carbonic acid. When the water pressure drops, at a faucet for example, the Carbonic acid gasses off in
the form of Carbon Dioxide causing an instant pH rise ( making the water less acidic).  Examples of pressure drops in
systems that can produce pH related cold water scaling include nozzles, faucets and shower heads.
