An ozone generator is an equipment that produces ozone. Ozone is a gas molecule with three oxygen atoms. It has a sharp, biting odor and is a powerful oxidizing agent. Ozone generators are used to purify air and water. In this blog post, we will discuss how an ozone generator works and some of its applications. Stay tuned!

You’ve undoubtedly heard of an ozone generator, but you may not be aware of what it is and how it works. An ozone machine, often known as an ozone generator, is a device that transforms ambient air, dry air, or concentrated oxygen into ozone.

Ozone (O3) is a toxic gas, commonly called the “oxygen killer,” that is produced by exposing oxygen molecules to energy in an ozone generator. The atmosphere is then disinfected and purified with the help of nitrogen dioxide. Ozone generators range from small hand-held versions to large industrial models that can generate hundreds of grams of ozone each hour. Industrial ozone generators operate similarly to ambient air devices, but they require very clean and dry air or oxygen and have a corona cell specifically built to create very high levels of ozone.

Ozone is produced when a high voltage is applied to the air that goes through it. This transforms some normal oxygen atoms into hazardous single atoms, which bind with other oxygen molecules to form ozone.

When the ozone is generated, it reacts with a pollutant, germs, viruses, or mold to break it down into smaller (and typically less harmful) chemicals through oxidation. Over time, free ozone will decompose into oxygen if it has not reacted with other particles. The process of ozonation eliminates scents and disinfects the air, water, and other items. It’s also been authorized for food usage by the USDA and FDA.

Ozone Generation

Lightning and sunlight are two natural ways in which the ozone generation process occurs naturally in the environment. We all know what a thunderstorm smells like, don’t we? It’s probably because of nature’s production of ozone that we notice the fresh, clean, spring rain smell after a storm. The second technique is to use UV light from the sun. When oxygen is exposed to sunlight, it may be broken down and converted into ozone using this method.

Corona discharge generators and UV light generators are two types of ozone generators that produce ozone on site.

Corona Discharge

O3 is produced by these machines through the use of an electrical grid that passes oxygen and pressure. The high voltage breaks down the oxygen molecules into single atoms. These fragments join together with other O2 molecules in the air to form ozone (O3).

The main advantages of corona discharge are that it generates a constant amount of ozone, it generates high ozone concentrations, it promotes fast organic (odor) removal, and it’s appropriate for water applications.

Ultraviolet (UV) Light


The sun’s ultraviolet radiation breaks down O2 in a similar method to how the ozone is generated. When a wavelength of 254 nm (nanometers) strikes an oxygen atom, UV light changes it into ozone. The molecule (O2) breaks down into two atoms (O) that combine with another oxygen molecule (O2) to form ozone (O3).

UV Light has several benefits over corona discharge, including a lower cost, ease of construction and use, and less humidity sensitivity with respect to the ozone output.

Types of Ozone Generation Systems

Ozone is often generated through the interaction of UV radiation and corona discharges, although there are two methods: UV light and corona discharge. Another distinction between ozone generators is whether they produce aqueous or gaseous ozone.

Aqueous Ozone Systems

Aqueous ozonators are devices that deliver gaseous ozone into water. The ozonated water may then be used to disinfect surfaces or circulated in water systems. From food disinfection to clean-in-place (CIP) processes to wastewater treatment, the applications are virtually infinite.

Ozone is more efficient at eliminating viruses and germs than chlorine or UV disinfection, with far less contact time and therefore shorter overall treatment times while still leaving no chemical residues. Ozone effectively destroys germs and viruses, causing cell membrane rupture and decomposition of essential biomolecular components due to its high oxidation potential. This leaves the water free of germs and viruses.

Water treatment systems that use ozone are often restricted in their application because there are no poisonous by-products generated as a result of the process. When ozone is used to disinfect water, it returns to oxygen. Ozone treatment also inhibits bacterial regrowth, assuming that other treatments have reduced pollutants in wastewater.

Gaseous Ozone Systems

Gaseous ozone generators may be utilized in a variety of air treatment and odor control applications. To rid the air of both airborne pollutants and lurking on exposed surfaces, ozone is circulated throughout the room. You can effectively eliminate or reduce airborne smells and contaminants by utilizing ozone and its oxidation mechanism.


Ozone is beneficial in the air and water treatment because it helps kill bacteria, viruses, and other pollutants. If you are looking for an easy way to improve the air and water quality in your home or office, consider investing in an ozone generator.
