Pool ozone generator: chlorine-free swimming pools

Ozone pool generators are a great alternative to traditional chlorine-based pools. With the use of ozone, the need for potentially harmful chemicals like chlorine is greatly reduced, making the water safe for swimming.

Reducing chlorine usage by 90% with ozone

Chlorine is the most commonly used disinfectant in swimming pools, but it has its drawbacks. Its strong odor and potential to irritate skin and eyes are concerns for many people. In addition too much chlorine with organic substances may lead to trihalomethanes (THM). Ozone, on the other hand, is a natural alternative that can disinfect pool water more efficiently than chlorine, reducing the need for chlorine by up to 90%. However, several governmental agencies require a minimal chlorine residual..

Ozone vs. chlorine in water parks and swimming pools

Although chlorine is still the most popular disinfectant for water parks and swimming pools, ozone is becoming increasingly popular.

Chemical-free solution

One of the major benefits of ozone is that it leaves no harmful chemicals behind after disinfecting the water. Chlorine, on the other hand, can produce dangerous by-products like trihalomethanes and chloramines when reacting with organic matter in the water.

No physical discomfort

Ozone is a non-irritating disinfectant that is a good choice for pool water disinfection. Chloramine, a known irritant that can cause redness, itching, and burns, is produced when there is too much chlorine present. However, ozone does not produce any of these unfavourable effects or side effects.

Cost savings

Ozone is a more potent disinfectant than chlorine, producing the same effects with less effort. Using ozone to disinfect water in swimming pools and water parks can result in long-term cost savings.

Other applications


Ozonation of air and water is increasingly valued in the agri-food industry. On-site creation of ozone eliminates the need for chemicals such as chlorine, hydrogen peroxide, and peracetic acid. Moreover, it destroys a wide range of harmful bacteria, including Salmonella, E. coli, and norovirus, providing environmental and financial benefits.

Aquaculture And Public Aquarium

Ozone treatment is the optimal choice to ensure a healthy environment for living organisms in aquaculture and public aquariums. Ozone treatment disinfects recirculated water without endangering marine life.

Odor Treatment

Treating the air with ozone is an efficient and all-natural way to eliminate unpleasant odors caused by aromatic molecules. Commercial buildings' plenum air return systems, restaurant ventilation pipes, and waste rooms often use ozone to create a healthy environment, odor free.


In the context of industrial water treatment, ozone treatment is able to oxidize wastewater contaminants such as cyanide and arsenic. Moreover, it facilitates the precipitation of several metals, including iron and manganese, as well as organic materials that are challenging to process biologically. Ozone technology offers a lasting solution for wastewater reuse and recycling, which is in high demand in arid regions around the world.


Ozone treatment has been tried and tested for decades and is the best way to ensure safe drinking water for everyone. Ozone kills a variety of bacteria, viruses, and odor-causing substances in water, including hydrogen sulfide (H2S). Furthermore, ozone removes water coloration due to its oxidizing properties. Ozone is the best option for treating the emerging pollutants in municipal wastewater.

Cooling tower

Ozonation of water in cooling towers enhances the ability to control bacteria like Legionella, making it a highly effective and safe method. Ozone is produced on-site and is extremely stable at various pH levels. Ozone works 3,000 times faster than chlorine in water treatment of this type. Ozone replaces the ongoing requirement for biocides, offers financial efficiency, and provides peace of mind knowing that the water has received appropriate treatment. LEARN MORE
