How Ozone Generator Works? Here Is What You Need To Know

Are you also looking for how ozone generator works? You’ve landed at right place. This blog post will cover everything you need to know about ozone generators. The term ozone generator may sound familiar to you, but you may not understand how it works. An ozone generator, or ozone machine, produces ozone by converting various oxygen sources into ozone, such as ambient air, dry air, and concentrated oxygen. In ozone generators, oxygen molecules (02) are energetically recombined with other oxygen molecules (03) to produce ozone (03).

The ozone is used today to disinfect water and purify the air. Small ozone machines can produce as much as 10 grams of ozone an hour, while industrial-scale models can produce hundreds. An industrial ozone generator is very similar to an ambient air unit, except that it requires very clean and very dry air and has an extremely high ozone concentration generated by a corona cell.

What is Ozone?

Ozone (O3or trioxygen) in the lower atmosphere acts as an ultraviolet protection shield.  As a ground pollutant, it affects animals (including humans) and plants that are sensitive to it, negatively affecting their photosynthesis.  This makes smog possible.  It is commonly believed that ozone is directly produced by industrial plants and car exhaust.  In fact, ultraviolet light from the sun reacts with hydrocarbons and nitrogen oxides in the air to produce ozone.  Depending on the direction of the emission, ozone is formed at the source or is formed several miles away (downwind).

However, ozone can be generated on demand using ozone generators that offer plenty of benefits.

How These Machines Generate Ozone

Air passing through ozone generators is charged with electricity. As a result, normal oxygen molecules are split into unstable single atoms, which then combine with other molecules of oxygen to form ozone. The process of ozone production involves reacting with pollution, bacteria, viruses, and mold and breaking them down into less complex (and often less harmful) molecules. Unreacted ozone decomposes over time into oxygen. In addition to destroying odors, ozonation disinfects water, air, and other materials. This method is even allowed for use in food processing by FDA. It is important to follow safety guidelines, know the structure of the contaminants, and have a professional size the ozone generation unit accurately based on your facility.

Corona discharge and ultraviolet light are the two main ways ozone is generated.

Corona Discharge:

A high voltage metallic grid is used to force oxygen through these machines, resulting in ozone being created. During the process, oxygen molecules are split into single atoms by the high voltage. Ozone (O3) results from these atoms attaching to the 02 molecules in the air. Corona discharge has the advantages of creating a consistent ozone output, generating high ozone concentrations, and quickly removing organic (odor) substances from water.

Ultraviolet (UV) Light:


Oxygen is split into individual atoms by sunlight’s ultraviolet radiation, as is the process of ozone formation. Ozone is created when ultraviolet light at 254 nanometers (nanometers) interacts with oxygen atoms. As oxygen molecules (02) separate, ozone (03), made of two oxygen molecules (02), is formed. Normally, UV light is produced by the sun’s rays. Utilizing UV Light has the advantages of being less expensive than corona discharge, it is simpler to assemble and use, and it yields less ozone when humid conditions are present.

Ozone Generator Types

1. Ultraviolet Ozone Generators

Light sources are used to create ozone. One limitation of UV ozone generators is that they generate very little ozone, which may not be sufficient for large spaces. Air purification is their primary purpose. They are therefore only used in small spaces.

2. Corona Discharge Ozone Generators

A dielectric surface allows an electric field to be created in the corona discharge generator, which generates ozone. Ozone is formed when single oxygen atoms split apart from molecules of oxygen (i.e., O2). Corona generators only use air as a source of oxygen.

The excess heat produced by these types of generators should be considered when generating ozone with them. Corona discharge generators with a frequency of more than 1,000 Hz are the most efficient and cost-effective choice.

3. Cold Plasma Ozone Generators

There are several different types of cold plasma generators. A dielectric discharge produces cold plasma that exposes oxygen gas to oxygen. Through this process, oxygen, which is a diatomic molecule, gets broken down into single atoms, which are then recombined to give ozone. You might wonder, how did the cold plasma form in the first place? A high voltage is applied across the gap between the poles of this generator to create it with the help of noble gasses. Unlike other methods of ozone generation, this method is relatively expensive and produces five percent concentrated ozone. Nevertheless, this generator produces a lot more ozone than other generators.

4. Electrolytic Ozone Generators

One more way of obtaining concentrated ozone is through electrolytic generators. Water molecules are separated into hydrogen, oxygen and ozone by this generator, and hydrogen is then removed from the system. A twenty to thirty percent concentration of ozone can be obtained by this method.  

The most prominent applications are water ozone generators, spa ozone generators, industrial generators, and pool generators. Generators of this type are widely used by a number of industries and sectors. Typically, they are used to improve soil quality, control indoor air pollution, and get rid of odors in pharmaceutical plants, greenhouses, and wastewater treatment plants.

How Does Ozone Water Treatment Work?


Using ozone water treatment, bacteria and other waterborne pathogens are oxidized by dissolving ozone into water. Electricity and lightning are responsible for generating ozone in the atmosphere. Ozone generators mimic both UV and electrical processes in order to treat water with ozone. The most common ozone generators for water treatment are UV and electrical ozone generators. Ozone can also be produced electrolytically and chemically for water treatment.

A water treatment system that uses ozone can remove:

  • Bacteria
  • Hydrogen sulfide
  • Viruses
  • Parasites, such as giardia and cryptosporidium
  • Bad tastes and odors
  • Turbidity
