Report Overview

The global ozone generator market size was valued at USD 608.4 million in 2019 and is expected to grow at a compound annual growth rate (CAGR) of 6.9% over the forecast period. Rising investments towards up-gradation and expansion of wastewater treatment facilities coupled with the positive outlook towards industrial sector growth are expected to surge the product demand over the coming years. Ozone can reach every corner of the environment, unlike ultraviolet sterilization, which leaves some places unsterilized. It can be used for public transportation modes, such as high-speed railways, airplanes, ships, and buses, as it leaves no poisonous residue and can be produced by simple equipment.

China ozone generator market size

The ozone industry has seen rapid growth since the early 2000s in China owing to the rising product demand for the wastewater treatment industry. According to the statistics provided by the Chinese Ozone Association, more than 20 companies are manufacturing large-size generators, more than 400 companies are producing small- & medium-sized, and others are manufacturing mini generators for residential/personal uses.

Ozone gas has been proven to kill the SARS virus with a killing rate of 99.2% according to the experiment conducted by the national P3 labora640tory in China. COVID-19 is 80% similar to the SARS virus and it is sensible to predict that ozone could be equally effective in controlling and preventing the spread of COVID-19.

Ozone gas production is easy but difficult to control at certain levels because of the price of ozone sensors. Manufacturers are focusing on reducing the price of these sensors to make it an affordable air-cleaning unit for the residential sector. Amid the pandemic, few hospitals are using ozone for sterilization to control the spread, which, if proves effective, could create opportunities for the product manufacturers.

However, prolonged exposure to ozone can cause lung, throat, nose, and eye irritation; shortness of breath; can damage materials including fabrics, electrical wire coating, and rubber; and can exacerbate chronic respiratory diseases, such as asthma. All these factors are expected to restrict market growth over the coming years.

Technology Insights

Corona discharge ozone generators segment led the global market in 2019 and held over 40% of the overall share. It is projected to expand further at a significant CAGR over the coming years as these generators produce pure ozone with no hint of chemicals and gases. Furthermore, they are available in mid-range prices and produce therapeutic/medical-grade ozone, which drives their demand.

Cold plasma product segment is projected to register the fastest CAGR from 2020 to 2027 owing to the high ozone concentration and low oxygen and energy consumption by these generators. In addition, these systems do not require maintenance, have the highest discharge pressure, and have accurate dosing through built-in controllers. However, these systems are expensive, bulky, and heavy, which can hinder the segment growth over the forecast period.

Electrolytic generators are primarily used for water treatment as they use the oxygen present in the water to produce ozone. Chemical water treatment methods generally leave residues on the equipment and traces of chemicals within the water; however, electrolytic systems leave no residue or harmful by-products, create little to no extra heat, and have zero chance of ozone escaping into the air.

Ultraviolet systems are inexpensive but also the least efficient types of ozone generators and are usually not recommended for ozone therapy. The segment is expected to lose its market share by 1.3% over the forecast period on account of the low ozone output and concentration along with the frequent need to replace ballasts and bulbs in the equipment.

Application Insights

The air treatment application is anticipated to register the fastest CAGR of 7.8% over the forecast period due to the high demand for ozone generators as they can remove unpleasant odors and airborne chemicals. However, these devices only produce a high concentration of ozone and do not offer any particle filtration options, which can result in restricting their demand in this application segment.

These generators are mainly used in water and wastewater treatment plants as ozone is more effective in destroying bacteria and viruses. In addition, the ozonation process utilizes a shorter contact time and does not leave any residuals. The product demand in treating wastewater is expected to increase significantly owing to the fewer safety problems associated with its handling and shipping along with low maintenance costs.

The product is also used for groundwater remediation as it can successfully treat various BTEX, TCE, DCE, 1,4 Dioxane, and other common groundwater contaminants. In addition, these devices are also used for sewage and wastewater odor control, and treatment in cooling water towers. Furthermore, these devices are used to improve water quality in aquaculture systems, treatment of bottled water, processing of fruits and vegetables, and to disinfect surfaces in the gas phase.

End-use Insights

The municipal end-use segment led the global market in 2019 and accounted for over 43% of the global share. The segment is expected to expand further at a considerable CAGR over the forecast period on account of rising product demand due to its high oxidizing power and ability to oxidize heavy metals.

Commercial segment is also likely to generate a significant product demand owing to the high concentration of PM2.5 and PM10 coupled with the rising awareness regarding employee safety in workplaces. Furthermore, growing technological advancements along with the increasing prevalence of airborne diseases are expected to boost segment growth over the forecast period.

Global ozone generator market share

The demand for ozone generators in the industrial sectors, such as pharmaceutical, chemical, and food processing industries, has seen significant growth in recent years as these devices can easily decompose harmful substances like phenol and cyan. The residential segment is anticipated to witness the highest CAGR from 2020 to 2027. Major manufacturers have seen a rise in the demand for personal air purifiers owing to rising awareness.

Regional Insights

The APAC regional market accounted for the largest revenue share of over 38% in 2019 and is estimated to maintain its dominance throughout the forecast years. The market in China is expected to witness a CAGR of 8.6% owing to the rise in water shortages and worsened water pollution due to the effects of rapid urbanization and industrialization. As a result, the municipal government has started adopting sophisticated water treatment technologies, such as ozone disinfection, to reduce the odor and contaminants present in the wastewater.

According to a study published by the Lancet in 2017, more than 60,000 deaths occur due to air pollution every year in Japan. In addition, Japan has experienced a significant increase in mortality because of air pollution in the last 20 years. As a result, the demand for ozone air purifiers in Japan has seen an exponential increase over the last few years.

The U.K. government’s new clean air strategy is expected to create opportunities for the product manufacturers over the coming years as the strategy sets out the comprehensive action, which is required to create a coherent and stronger framework to get rid of air pollution and reduce the risk they impose on the public health and environment.

Overexposure of ozone is highly toxic and can alter VOCs to more dangerous forms, which is expected to restrict the market growth over the coming years. In addition, the ban of ozone generators in California since 2009 along with the ban in the production of air cleaning units that emit more than 0.05 ppm of ozone is expected to hinder the market growth in the U.S.

Key Companies & Market Share Insights

Major manufacturers are aiming to contribute to the improvement of the water environment and expand their regional presence to strengthen their market positions. One such company is Metawater that is planning to accelerate the expansion of its overseas business by utilizing silent discharge technology for efficient generation of ozone. Companies are focusing on manufacturing low-cost and highly efficient devices to gain a competitive edge. For instance, Toshiba’s latest innovation, TGOGS series; is designed for optimum efficiency in a less bulky package that can be used in large-scale water treatment plants and also benefits the environment.
