Ozone Generator Market Report 2026

The ozone generator market size has grown strongly in recent years. It will grow from $1.61 billion in 2025 to $1.74 billion in 2026 at a compound annual growth rate (CAGR) of 7.8%. The growth in the historic period can be attributed to increasing concerns over waterborne contaminants, growth in municipal water treatment infrastructure, rising demand for industrial air purification, adoption of ozone in pulp and paper bleaching, limitations of conventional chemical disinfectants.

The ozone generator market size is expected to see strong growth in the next few years. It will grow to $2.36 billion in 2030 at a compound annual growth rate (CAGR) of 8%. The growth in the forecast period can be attributed to stricter environmental and water quality regulations, growing focus on sustainable disinfection technologies, expansion of aquaculture and food safety applications, rising investments in wastewater treatment projects, technological advancements in ozone generation efficiency. Major trends in the forecast period include rising adoption of ozone based water treatment systems, growing demand for chemical free air purification solutions, increasing use of ozone generators in food processing, expansion of medical and aesthetic ozone applications, preference for energy efficient ozone generation technologies.

Increasing investments in upgrading and expanding wastewater treatment facilities are expected to drive the growth of the ozone generator market. Wastewater treatment plants address industrial effluent and remove pollutants through various methods, including physical, chemical, and biological processes. As water resources become increasingly scarce and climate change progresses, the importance of wastewater reuse has grown. The treatment of water with ozone begins with the generation of ozone (O3) in an ozone generator, where energy is applied to oxygen molecules (O2) to separate the oxygen atoms, which then temporarily recombine with other oxygen molecules, serving to disinfect and purify water. For instance, in August 2024, UN-Water, a Switzerland-based United Nations (UN) interagency mechanism, reported that globally, 42% of household wastewater was not safely treated before being discharged in 2022, resulting in an estimated 113 billion m³ released into the environment. This situation underscores the urgent need for improved water quality and the goal of halving untreated wastewater while enhancing recycling and safe reuse by 2030. Therefore, the rising investment in upgrading and expanding wastewater treatment facilities is anticipated to boost the demand for ozone generators during the forecast period.

Major companies in the ozone generator market are also developing innovative products like geodesic ozone generators to cater to a broader customer base, increase sales, and boost revenue. A geodesic ozone generator produces ozone (O3) through the ozone generation process. In October 2023, AquaStar Pool Products, a US-based pool technology company, introduced the PureStar Ozone System. This self-contained geodesic ozone generator, known for its simplicity in installation, is compatible with nearly all variable-speed pumps without increasing energy consumption. Its patented plug-and-play design seamlessly integrates in-line, requiring less than 18 inches of horizontal pipe. Featuring a venturi injector with self-regulation, it ensures hydraulic system efficiency, making it effective even when operating at lower speeds.

In May 2023, Xylem Inc., a US-based global water technology company, acquired Evoqua Water Technologies Corp., a Delaware corporation, for approximately US$7.5 billion in an all-stock transaction. Through this acquisition, Xylem Inc. sought to expand and strengthen its water-treatment solutions and services portfolio, substantially enhancing its industrial and municipal water management capabilities while extending its global presence. Evoqua Water Technologies Corp. is a US-based water-technology company that specializes in delivering water and wastewater treatment solutions and services for municipal, industrial, and commercial customers worldwide.
