Ozone Generation Market Size
As per the latest market research conducted by the CMI Team, the global Ozone Generation Market is projected to witness steady growth during the forecast period from 2025 to 2034, registering a compound annual growth rate (CAGR) of 5.91%. In 2025, the market size is expected to reach a valuation of USD 1.67 billion, and by 2034, it is anticipated to expand significantly to approximately USD 2.8 billion. This growth highlights the increasing adoption of ozone-based technologies across a wide range of applications, particularly in water treatment, air purification, and food processing sectors.

Ozone Generation Market Overview
According to industry experts at CMI, ozone generation is the process of producing ozone (O₃), a triatomic molecule composed of three oxygen atoms. This process is achieved using high-energy methods such as electrical discharges or ultraviolet radiation, which break down oxygen molecules (O₂) and rearrange them into ozone. Ozone is widely recognized for its strong oxidizing properties and is commonly used in disinfection, sterilization, odor control, and pollutant removal.

The ozone generation market is primarily influenced by several critical factors. Rising levels of air pollution and the growing demand for effective purification technologies are encouraging industries and governments to invest in ozone generators. The expanding water and wastewater treatment industry, supported by stringent government regulations aimed at controlling emissions and maintaining hygiene standards, is further driving market adoption. Additionally, increasing consumer awareness regarding health and hygiene, coupled with a stronger emphasis on food safety and preservation, is boosting the need for ozone-based solutions. Moreover, rapid technological advancements and investments in advanced ozone generation equipment are contributing to industry growth. However, the market faces certain restraints such as the short lifespan of ozone and limited awareness and expertise in handling the technology, which may restrict its full-scale adoption over the projected period.

Ozone Generation Market: Growth Factors and Dynamics

Growing demand for freshwater
Industries around the world require large volumes of freshwater for numerous applications, ranging from thermoelectric power generation, irrigation, and aquaculture to public supply and self-supplied industrial processes. With global climate change leading to rising temperatures and altered precipitation patterns, the demand for clean and accessible water is expected to rise further.

Governments and international bodies are increasingly investing in projects to ensure freshwater availability, which is driving demand for advanced ozone generation technology in water purification. For example, in 2022, the United States announced a three-year foreign water security and sanitation assistance initiative worth USD 1.2 billion. Such initiatives demonstrate the increasing reliance on advanced technologies like ozone generation to address global water scarcity challenges, thereby fueling industry growth.

Growing venture to launch an innovative product
Collaborations and joint ventures among key market players are expected to open significant opportunities for growth in the ozone generation market. Companies are focusing on innovative product launches to enhance efficiency and affordability while addressing environmental and health concerns.

For instance, in January 2023, Konica Minolta, Inc. entered into a collaboration with Tamura TECO Co., Ltd. to develop the second generation of its ozone generator. The partnership resulted in the mass production of BACTECTOR 2.0SC, a cost-effective product with advanced proprietary functions designed to effectively disinfect and suppress bacteria and viruses. This product aims to promote safer and cleaner environments and is being used at DMC-MIKAWA, Japan’s smart factory. Such developments demonstrate how technological progress and collaborations are fostering market expansion.

High maintenance and installation cost
Despite its benefits, ozone technology comes with considerable installation and maintenance costs, which can act as a barrier to adoption. The cost of ozone disinfection systems for municipal water treatment varies depending on the plant’s size, location, water quality, and the system manufacturer.

Compared to other disinfection methods such as chlorine or ultraviolet (UV) light, ozonation is often more expensive. According to the Environmental Protection Agency (EPA), ozone disinfection is the least commonly adopted technology in the United States due to high upfront and operating costs, despite its superior disinfection capabilities. Ozone systems are generally chosen in cases where alternative treatments prove ineffective.

The capital cost of an ozone generator is estimated to account for approximately 8% of the total investment in constructing a water or wastewater treatment plant. Additionally, the operation and maintenance (O&M) expenses of ozone systems range between 1.9% and 3.7% of the total O&M expenditures of such plants. These financial considerations are critical factors limiting wider adoption in cost-sensitive regions.

Ozone Generation Market: New Launches and Acquisitions
The industry has been witnessing notable product launches and strategic acquisitions aimed at strengthening market presence and addressing the increasing demand for ozone solutions.

For instance, in April 2022, Toshiba Corporation announced an agreement to deliver three ozone generators to Larsen & Toubro Limited for installation at the Delhi Jal Board’s Chandrawal Water Treatment Plant in Delhi, India. This system represents one of the largest ozonation projects in India designed for wastewater treatment. Such large-scale projects not only highlight the growing importance of ozone generation in water treatment but also reflect the expanding opportunities for manufacturers in emerging economies.
