IONIZATION HISTORY
The principal of using metals for water purification goes back hundreds of years. Silver’s effectiveness dates back to the middle ages; it was used in the viaducts and water vessels. Settlers used coins in water barrels to keep their water pure. It was apparent this worked, but no one really knew why.
The first reasonably modern attempts to use this ionization process were made in the 1930’s. Then, in the 1960’s and early 1970’s the Johnson Space Center conducted a research program aimed at the development of a small, lightweight water purifier that required minimal power and no human monitoring. This program produced an electrolytic silver ion generator, slightly larger than a pager and weighing only nine ounces. One or more units, mounted at various locations in the potable water supply and waste water system of a spacecraft, would dispense silver ions sufficient to eliminate bacteria and sanitize the water within hours.
NASA made this design information available to the industry and from this beginning, one of the world’s most advanced water purification systems was developed. It is capable of handling water volumes into the millions of gallons and is used in many different applications. Pools spas, decorative water applications, cooling towers, injection molding systems all routinely use ionization as a means of water sanitation.
HOW IT WORKS
Both copper and silver have some algacidal and bactericidal properties. Copper has the ability to pierce the protective outer membrane of a cell and disrupt enzyme balance, as well as allowing other bactericides and algaecides access to the susceptible part of the organism. Silver is effective because of its capabilities of interfering with DNA production and accelerating the death phase. Although lethal to bacteria and algae, this process is completely safe to humans. A multitude of scientific tests have been done showing the effectiveness of copper-silver ion systems in different areas including swimming pool and spa applications.
BENEFITS
There are a number of advantages to the electrolytic system. Unlike standard sanitizing chemicals, ions are relatively unaffected by pH, temperature, aeration or sunlight. As they are not as prone to evaporation or dissipation, they tend to remain resident in the water to provide long-lasting and constant purification. New ions are added automatically as the water circulates. It is easy to use. Operation and maintenance are low. From a health standpoint it is completely safe, as no toxic chemicals are produced or consumed. The system is environmentally friendly and the water is healthy, sanitary and odor free.
These are specific advantages for residential pool and spa owners.
- Water quality is improved dramatically.
- The water feels fresh and clean with no chemical smell.
- Ion systems are ideal for those who are allergic or very sensitive to standard sanitizing chemicals.
- It is non corrosive.
- It is chemically neutral, so water balance is often easier to maintain.
