Today, ozone is the most powerful oxidizer available in commercial use. In North America, it is gaining market shares rapidly for swimming pool treatment systems. It is best known for its crystal clear, odorless water. The swimmers are not left with red eyes, rashes, itching or other skin irritation problems after the ozone treatment.


  • The sanitizing properties of ozone are much faster than those of chlorine.
  • Ozone makes water clearer.
  • Swimsuits do not degrade or sting when exposed to ozone.
  • The pool area does not emit any harmful fumes.
  • Automatic production eliminates the need for manual labor. No intensive maintenance is required.
  • All filters are much more effective when treated with ozone.
  • Among all available sanitizing systems, ozone is the most cost-effective.
  • The presence of ozone enhances the filtration process by flocculating organic wastes.
  • Organic waste is directly decomposed by ozone through oxidation.
  • Bacteria, viruses, and fungi are virtually all killed by dissolved ozone residuals in water.
  • Water oxygenation: Unused ozone is converted to normal oxygen and remains dissolved in the water until it reaches saturation point. Result: sparkling and clean pool water.
  • No toxic residues remain in the water after treatment.
  • Production is done on-site and there is no need to store or transport the product.
  • There are no adverse health effects associated with ozone systems.
  • Microorganisms are destroyed by ozone, calcium carbonate is prevented from scaling and removed from pool walls, exposed metals are reduced in corrosion, and greasy sediments are cleaned and prevented from occurring.
  • Water treated with ozone is much cheaper to clean.
  • Numerous hospitals and rehabilitation centers use ozone to treat patients. Chlorine is no longer required as a backup for today’s ozone technology, except in case of maintenance or power failure (bromine is considered safer and more reliable).
  • It has been verified that pools require 0.125 to 0.150 grams of ozone per cubic meter of pool volume. Public, commercial and hospital pools have all confirmed this requirement. However, private pools have lower dosage requirements.
  • Swimming in ozonated water has no known negative effects.  
  • Ozone generators designed to meet the specific size requirements can provide all the ozonation power needed for purifying, oxygenating, and sanitizing swimming pools, whirlpools, and lakes. An automated process maintains the desired level of ozone production.

Ozone is becoming a sanitizer of choice for pool managers as problems with chlorine systems continue to grow. Most notably, chloro-organic compounds (COCs) and trihalomethanes (THM) are cancer-causing byproducts of chlorine systems. These reductions not only eliminate the production of these compounds, but they also reduce or eliminate maintenance issues associated with these gases. 

Eliminate Red Eye, Rashes

The concentration of THMs and chloro-organic compounds can be extremely high in swimming pools. There is a much greater risk to human health when red eyes and rashes occur.

Approximately half a liter of pool water is absorbed by the human body every hour. Swimming pools with the best water quality are compliant with drinking water standards. In this case, ozone generator can be your best option to deal with this issue.

Why Ozone?

Ozone is non-irritating and does not break down into irritating substances. Mold, mildew, spores, yeast, and fungus are also killed by ozone. Additionally, ozone is PH neutral and does not add contaminants to water. In fact, where pools use a dual system of sanitation (i.e. chlorine or bromine), ozone actually inhibits the formation of chloro-organic byproducts and THMs. Ozone reduces or eliminates the caustic gases formed by chlorine, which can lead to maintenance problems such as rusting, premature wear, and other chlorine-related problems.

Bottom Line

There are over 300,000 swimming pools in Europe treated with Ozone and the number of pools in North America continues to grow as the benefits become apparent. In addition to killing bacteria, viruses, and protozoa, ozone can kill Giardia and Cryptosporidium, which can cause severe gastrointestinal illness but are much less effective than chlorine at eradicating them. Additionally, it prevents endotoxins from being released into the air after standard chlorine water treatment.
