Ozone Generation Market: Overview

Ozone generation refers to the process of generating ozone (O3) from molecular oxygen (O2). The process of generating O3 typically uses ultraviolet light or electrical discharge to split oxygen molecules and promote free oxygen to combine with existing O2 molecules. Demand for ozone generation is growing due to rising end applications of O3 across several industries. For instance, ozone is a widely used component for water purification. In addition to this, industrial applications of ozone in bleaching pulp and chemical synthesis procedures further contribute to the increased demand for solutions that generate ozone. The three most common methods of ozone generation include ultraviolet radiation, corona discharge, and electrolysis.

During the forecast period, demand for ozone generation is expected to grow continuously. The increasing applications of O3 across small and large-scale wastewater purification facilities will propel market revenue. Additionally, the increasing development of new technologies and techniques for ozone production may generate novel growth opportunities for the industry players. However, O3 also poses several health risks as it can induce serious respiratory conditions. Moreover, regulatory hurdles will continue to impact market revenue in the long run.

Ozone Generation Market: Growth Drivers

How will the rising demand for O3 in wastewater treatment facilities fuel the ozone generation market expansion?

The global ozone generation market is expected to be driven by the growing demand for O3 in treating and managing wastewater. According to market analysis, ozone is a highly powerful oxidizing agent. It is known to kill viruses, bacteria, and other contaminants. Furthermore, O3 has proven highly effective in oxidizing critical organic compounds such as hormones or pharmaceutical pollutants.

Since ozone production does not require the use of external chemicals, as it is produced onsite using air, O3 is considered safer for treating wastewater. In the last few years, ozone has been extensively used across municipal-grade wastewater plants. During the forecast period, as investments in construction and development of new wastewater facilities grow, demand for ozone generation will continue to rise.

In September 2024, Severn Trent, one of the UK’s largest water utility companies, announced it had begun the construction of the region’s first pioneering operational ozone wastewater treatment plant. The facility will be equipped with state-of-the-art technology and will be constructed with an investment of EUR 78 million. The unit is expected to improve river health in the United Kingdom. The growing concerns over the shortage of usable water and the increasing rate of water pollution will promote the use of ozone for purifying water bodies, thus helping the industry for O3 generation thrive.

Growing concerns over air pollution to propel demand for O3 generation in the coming years

Ozone is widely used in air purifying systems, especially in indoor settings such as commercial buildings and hospitals. O3 can efficiently kill harmful pathogens in the air and also tackle the presence of volatile organic compounds (VOCs). The growing rate of air pollution worldwide, caused primarily by the increasing use of internal combustion engines, deforestation, industrial emissions, and agricultural activities, will facilitate higher demand in the global ozone generation market in the coming years.

For instance, in 2024, several cities in India were ranked among the most polluted regions in the world. Inhaling contaminated air is associated with several health conditions, including cancer and serious respiratory disorders. The growing awareness about the importance of clean air in indoor settings will aid in improved market revenue in the coming years.

Ozone Generation Market: Restraints

How does the health impact caused by long-term exposure to O3 limit the ozone generation market expansion?

The global ozone generation industry is expected to be restricted due to several health concerns associated with long-term exposure to O3. Ozone can produce toxins at ground level, and it can lead to several health hazards. Exposure limit to ozone at ground level is heavily regulated under regional and international guidelines. Failure to comply with the regulations can result in severe penalties and also lead to public health hazards. These factors are likely to impede market expansion in the coming years.

Ozone Generation Market: Opportunities

Will the increasing introduction of novel O3-generating solutions create growth opportunities for the ozone generation industry?

The global ozone generation market is expected to generate growth opportunities due to the rising introduction of new solutions assisting in generating O3 for final applications. In May 2025, RainHarvest Systems, a leading provider of water harvesting, treatment, and reuse technologies, announced the launch of a new range of ozone generator product lines. The Pro Series of novel ranges is designed to meet the current demands of end-user industries. The ozone will be delivered using venturi side stream injection, which will ensure maximum output with precise dosing. Currently, the three variants available in the range can produce up to 30 grams of ozone per hour.

In January 2023, Konica Minolta, Inc., a Japan-based industry player, launched its second ozone generator in collaboration with Tamura TECO Co., Ltd. The latter is a prominent company offering ozone-related products. The companies have initiated mass production of BACTECTOR 2.0SC. It is an affordable high-cost-performance product showing powerful deliverables.

In October 2024, Salher announced the launch of OZ Wizard. It is the company’s latest automatic ozone-generating equipment offering advanced solutions for water purification. OZ Wizard is also environmentally friendly, making it highly popular among end-user industries worldwide.

Ozone Generation Market: Challenges

High cost of infrastructure setup and the technical limitations of O3 affect market revenue

The global ozone generation industry is expected to face challenges due to the high investment costs associated with developing the necessary infrastructure for O3 generation and application.

Furthermore, the industry also faces competition from other affordable alternatives. The technical limitations related to O3 applications, such as short half-life and on-site generation, may further affect market growth trends during the forecast period.
