The global ozone generator market is expected to grow from $1.27 billion in 2021 to $1.34 billion in 2022. The compound annual growth rate was 6.0%.

North America is still the largest ozone generator market in 2020. This ozone generator global market report also covers Asia-Pacific, Western Europe, Eastern Europe, South America, the Middle East and Africa.

The increasing investments to upgrade and expand wastewater treatment facilities are expected to drive the growth of the ozone generator market. Wastewater treatment plants use a variety of physical, chemical and biological methods to treat industrial and household wastewater and remove contaminants. As climate changes and water becomes scarcer, the reuse of wastewater is becoming more and more crucial.

In ozone water treatment, the first step is to produce ozone with an ozone generator or other ozone generating equipment by applying energy to oxygen molecules. This will cause the separation of oxygen atoms, the temporarily recombination with other oxygen atoms and the formation of ozone. Ozone can be used to disinfect and purify water.

In April 2021, the EPA issued a notice announcing a total of $6.5 billion in new investments for water infrastructure projects. The funds will accelerate investment in critical water infrastructure through a variety of projects in large and small communities. Therefore, investments in the improving or expansion of wastewater treatment facilities will increase the demand for ozone generators over the forecast period.

The reason why there is a growing popularity of the ozone generator market is product innovation. More and more companies in the ozone generator business around the world are developing and adopting new products with innovative technologies to meet different industry needs.
