Ozone Water Treatment for Swimming Pools & Spas

Ozone water treatment for Pools & Spas


The Ozone Advantage – the purest water you will swim in!

Ozone is often referred to as Nature’s Cleaner: it is the most effective disinfecting agent commercially available.

Ozone is widely used in Europe and North America to sanitize air and water.

It is environmentally friendly and economically efficient.  Ozone greatly diminishes the need for alternative chemical sanitizers, like chlorine, and in some applications may also reduce water consumption.

Unfortunately, obtaining reliable and cost-effective ozone systems in Australia has not been easy – until now. Over the past ten years research and development conducted by Ozone1 has made possible affordable, efficient and easy-to-use ozone systems for pool water sanitation.  These products incorporate a corona discharge reactor – as opposed to UV lights – thus ensuring reliable, consistent and cost-effective ozone levels



The main benefits of the Australian-made Ozone Swim systems are as follows:
  • Ozone Swim allows pool owners to dramatically reduce the amount of chlorine required, therefore extending the life of expensive salt cells and greatly reducing the amount of balancing chemicals required.
  • Ozone is a natural flocculant which improves the clarity of the water without having to add chemicals.
  • Ozone will safely and effectively destroy chlorine by-products (the direct cause of irritations) as well as chlorine-resistant parasites such as Cryptosporidium
  • Ozone breaks down contaminants approx 3500 times faster than chlorine, leaving only oxygen as a residual.
Maintenance: The maintenance for an Ozone Swim system swimming pool is less than for traditional chlorinators as the Ozone component has no moving parts and requires little to no maintenance.  For example,  there is a pre-filter that we recommend replacing every 6 months (half a cotton wool ball) and a check valve we recommend replacing every 12 months.   Balancing chemicals will be greatly reduced, but not entirely eliminated.


Ozone water sanitation for pools, spas & water features

This is THE solution for clean, hygienic pool water without the smell and irritation caused by high levels of chlorine.  If it is crystal clear – it’s ozone!

Ozone has been used for nearly a century in Europe and the USA to sanitise and purify water.   In southern California, for example, ozone has approval for all aqueous applications.   Now it can be used safely and cost-effectively to keep your pool, spa, or water feature clean and healthy.

Ozone1’s OzoneSwim product line combines the benefits of salt water chlorination with the power of ozone to create the ultimate in soft, sanitary, and odour free water.   OzoneSwim products are the ideal solution for pool owners that want high-quality water, while at the same time want to reduce their reliance on pool chemicals.

OzoneSwim is the ideal solution for treating pools, spas, and water features because it:

  • Disinfects by rapidly killing all types of bacteria, fungi, viruses, and cysts
  • Breaks down dissolved impurities such as oils and organic wastes
  • Improves filtration of suspended solids


Advantages of Ozone.

Ozone Swim Pool Sanitation Systems are a proven and effective complement to chlorine and other chemical-based systems to disinfect your swimming pools. Ozone in combination with chlorine is known as the Dynamic Duo – a powerful oxidizing combination.

The primary advantage of Ozone Swim sanitation systems is that Ozone significantly reduces the formation of chlorine by-products, notably chloramines and trihalomethanes.  These by-products are readily apparent in indoor environments because they can create a strong smell, but occur in outdoor pools as well.   Monitored trials have shown chloramine levels dropping to .08 ppm.  Because of the reduction in chlorine by-products, there will be fewer complaints about red eyes, dry, itchy skin, and respiratory ailments.   Ozone also oxidises oils and other contaminants within the water, leaving the water purer.

Ozone Swim systems are easily adjusted to suit bather load, temperature, turnover rate, and primary disinfection method.


How Ozone works.

Most of us have heard about ozone but only know it as the layer in the upper atmosphere that protects the Earth from harmful radiation.

Ozone is triatomic oxygen (O3). It is made both commercially and naturally by a high voltage electrical discharge process which converts oxygen (O2) into ozone. For instance, it is ozone that gives the distinctly fresh odour you can smell after an electrical thunderstorm. In fact, the name ozone is derived from the Greek word “ozein”, which means “to smell”, in recognition of its unique odour. Man-made ozone simply mimics nature’s manufacture in devices known as corona discharge reactors.

Discovered in the 1840s and used commercially in water treatment
for over 100 years, ozone is a very reactive gaseous compound that rapidly breaks down most organic molecules while quickly killing most single-cell micro-organisms. In fact, ozone is the most effective disinfecting agent commercially available. Ozone also has a very short half-life, with simple oxygen as its decomposition or reaction product. Indeed, ozone is often referred to as “Nature’s Cleaner” because its use will not result in the formation of other environmentally persistent and toxic chemicals, such as the formation of chlorinated hydrocarbons seen with the use of chlorine.

For these reasons, ozone is now commonly used in lieu of chlorine and other chemical additives for water sanitisation and air purification in the following industries:

  • Cooling towers for sanitation, corrosion control, and scale control
  • Swimming pools, spas, and water features for disinfection
  • Municipal/industrial wastewater for disinfection, odour control, and water reclamation
  • Food processing for wash water and cold storage sanitation
  • Potable water for disinfection and organic oxidation
  • Pulp and paper products for bleaching and waste treatment
  • Fish hatcheries/aquaculture for disinfection

Incorporates a patented corona discharge Ozone cell, and comes complete with an injector manifold.

Designed to reduce chlorine levels by 80%, works in conjunction with existing Salt Chlorinators, Chemical dosing systems, and tablet feeders. It is also suitable for water features.

Questions & Answers…

What is Ozone?

Ozone is triatomic oxygen (O3). Ozone is created naturally in the atmosphere; in fact, you are breathing trace elements of ozone right now.
Ozone is widely used to sanitize both air and water.   For example, if you drink bottled water odds are it is ozonated; when boarding international
flights that fresh smell at the door is ozone to disinfect air entering the plane.   One of the great properties about ozone is that it is environmentally
friendly: when injected into pool water it breaks down within minutes into simple oxygen, but when doing so it kills bacteria, fungi, viruses, and cysts
that can exist in pool water, as well as breaking down dissolved impurities, like suntan cream. Unlike chemicals, there is no long-lasting residue.

How does ozonating my pool benefit my family and me?

A common complaint amongst pool and spa owners is that the water irritates the eyes and causes dry, itchy skin. Ozonated water will not do
that.   Our systems combine the benefits of chlorination with the power of ozone; but importantly, because ozone is injected into the water, the
chlorinator is turned way down.   We recommend running your chlorinator at one third its current level.   Within days you will notice that your swimming pool water is noticeably softer, crystal clear, and odour free.
Is ozonating my pool cost-effective?

Our ozone-based systems are less expensive to run than current chlorination systems:   Because the chlorinator unit is turned down, electricity consumption is reduced.    In addition, barring a heavy pool load (due to large numbers of swimmers, ducks in the pool, leaves, and debris not removed, etc.), the need to add chemicals is reduced.    Fewer backwashes will also be required.

Are there other environmental or health and safety advantages?

Because ozone has a very short half-life (in the order of minutes in the water), ozone cannot build up in the water to unsafe high levels as is the case with other chlorine, bromine, or organic-based biocides.    And because ozone decomposes into simple oxygen, ozone-treated pool water is further oxygenated helping it maintain its freshness and clarity.   Further, ozone will not form chloramines or other chlorinated hydrocarbons upon reaction with organic material in the pool water.    Chloramines, formed by the reaction of chlorine with organic material in the pool are the actual source of most offensive odors associated with highly chlorinated pools rather than the chlorine itself.    Chloramines are also responsible for the eye and skin irritation many people experience when using excessively chlorinated pools.    Other chlorinated organic by-products found in pools have been associated with a variety of human ailments including allergies.

If ozone is so effective at purifying water, why use chlorine with ozone?

Proper use of ozone will provide the bulk of water purification and sanitation needs for swimming pools including sanitization and control of organic levels resulting from swimmers’ body oils & lotions.    Remember, however, that ozone very rapidly breaks down into simple oxygen within minutes of injection into the water.    Although this is advantageous from an environmental and health and safety point of view, it will also result in insufficient ozone residual in the swimming pool water in spots of the pool far removed from the ozone-treated water inlet into the pool.    To provide for sanitization in all parts of a pool, small amounts of chlorine are also used in ozone-treated pools to provide a residual disinfectant.   However, the amount of chlorine added to provide a minimum residual throughout the pool is drastically reduced when using ozone because the ozone destroys most organic material preventing it from reacting and consuming the added chlorine.
