Ionic Water Treatment
An ion is an atom, or group of atoms that possess an electrical charge. Ions exist
everywhere and your pool is full of ions. It was discovered long ago that copper ions
behave as an algaestat, that is, they inhibit algae growth, while silver ions behave as a
bactericide, that is, they kill bacteria.
An ionizer is a device that uses electricity to produce these metal ions right in the
plumbing, so they are dispersed into the water to do their work. Copper and/or silver
electrodes are energized with a low voltage, DC current supplied from the equipment sub
panel. The voltage is applied to two metallic electrodes placed in close proximity to each
other within the plumbing pipe. The electrical current causes atoms of the copper or
silver electrode to lose an electron and become
cations. These cations are drawn towards
the opposite electrode, but are swept away by the rushing water passing by. After this
introduction in the water, these ions float dissolved in water until they encounter a
microorganism.
Ionization is not a stand alone sanitizer. It cannot oxidize organic matter
effectively, so additional chlorine or
non-chlorine shock treatment is necessary. There
also is the potential for staining of interior surfaces. Copper can deposit itself on
these surfaces, giving a blue-green color, {which isn't too bad to look at, some pool
people like the color}. Silver can react with sunlight, similar to the way photographs are
produced, and create black stains on the plaster.
Ionizers can reduce reliance on traditional chemicals, or provide additional power to
your sanitation program. |
