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.
