Water Treatment Ozone Generator Market Report 2026

The water treatment ozone generator market size has grown strongly in recent years. It will grow from $1.57 billion in 2025 to $1.68 billion in 2026 at a compound annual growth rate (CAGR) of 7.1%. The growth in the historic period can be attributed to expansion of municipal water treatment infrastructure, rising demand for potable water quality improvement, increased use of ozone in industrial wastewater treatment, growing awareness of chemical-free disinfection, adoption of ozone in food and beverage processing.

The water treatment ozone generator market size is expected to see strong growth in the next few years. It will grow to $2.2 billion in 2030 at a compound annual growth rate (CAGR) of 7%. The growth in the forecast period can be attributed to increasing water scarcity concerns, rising investments in sustainable water treatment technologies, expansion of decentralized water treatment systems, growing adoption of ozone in aquaculture and healthcare, increasing regulatory emphasis on advanced water purification. Major trends in the forecast period include increasing adoption of chemical-free water disinfection systems, rising deployment of ozone-based advanced oxidation processes, growing integration of smart monitoring and control systems, expansion of modular and scalable ozone generator designs, enhanced focus on energy-efficient ozone generation.

Increasing concerns over water pollution are expected to drive the growth of the water treatment ozone generator market in the coming years. Water pollution refers to the introduction of toxic or harmful substances into water sources, making them unsafe for human use and damaging aquatic ecosystems. This rise in water pollution is largely due to industries discharging untreated waste into water bodies, resulting in harmful chemical contamination. Water treatment ozone generators address this issue by producing ozone, a powerful oxidizing agent that effectively removes pollutants, bacteria, and organic compounds. This process purifies water without leaving toxic byproducts, ensuring both environmental and human safety. For example, in August 2025, the Environment Agency, a UK government department, reported that in 2024, pollution incidents from sewerage and water supply assets increased by 29% compared with 2023, a rise deemed unacceptable. Consequently, growing concerns over water pollution are fueling the expansion of the water treatment ozone generator market.

Companies operating in the water treatment ozone generator market are focusing on developing advanced, environmentally friendly water disinfection systems to improve treatment efficiency and meet rising regulatory and sustainability demands. These systems use sustainable methods or advanced filtration to remove harmful microorganisms and pollutants without the use of toxic chemicals, ensuring clean water without harmful residues. For instance, in October 2024, Salher, a Spain-based provider of urban and industrial wastewater treatment solutions, introduced the OZ Wizard, a compact and modular ozone generation system. Designed for municipal water supply, the OZ Wizard effectively eliminates microorganisms and contaminants without leaving harmful residues. This environmentally friendly solution supports sustainable water treatment by using corona discharge technology to produce ozone, offering a chemical-free and cost-effective way to improve water quality and protect environmental resources.

In May 2023, Xylem Inc., a US-based water technology company, acquired Evoqua Water Technologies for approximately \$7.5 billion. This acquisition strengthens Xylem's leadership in the water treatment industry by integrating Evoqua’s advanced water technologies and services, creating a comprehensive platform to address critical water issues such as scarcity, quality, and resilience. The acquisition enables the combined company to offer a broader range of solutions to utilities, industrial, and commercial customers globally. Evoqua Water Technologies LLC, based in the US, provides ozone generators for water treatment solutions.
