The global ozone generator market size is projected to surpass USD 1.1 billion by 2027, according to a new report by Vision Research Reports.
The global ozone generator market size was valued at USD 609 million in 2019 and is expected to grow at a CAGR of 7% over the forecast period 2020 to 2027.
Rising investments in up-gradation and expansion of wastewater treatment facilities are expected to boost the product demand over the coming years.
Prolonged exposure of ozone can cause lung, throat, nose, and eye irritation; shortness of breath; can adversely affect indoor plants, 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.
The demand for ozone generators in the residential segment is anticipated to witness the highest growth. Ozone can reach every corner of the environment, unlike ultraviolet sterilization, which leaves some places unsterilized. It also leaves no poisonous residue and can be produced by simple equipment, which can be used for public transportation modes, such as high-speed railways, airplanes, ships and buses; single rooms; and large public places.
Corona discharge ozone generators segment led the global market in 2019 and held over 41% 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.
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 1.4% 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.
The air treatment application is anticipated to register the fastest CAGR of 7.9% over the forecast period due to the high demand for ozone generators as they can remove unpleasant odors and airborne chemicals.
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.
The municipal end-use segment led the global market in 2019 and accounted for over 43.3% 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.
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.
The APAC regional market accounted for the largest revenue share of over 39% in 2019 and is estimated to maintain its dominance throughout the forecast years. The market in China is expected to witness a CAGR of 8.7% 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.
