Report Scope and Ozone Generation Market Segmentation

What is the Key Trend in the Ozone Generation Market?

• Ozone generation is increasingly shifting from basic corona discharge units toward energy-efficient, modular, digitally monitored systems, combining high-concentration generators, advanced cooling, automated controls, and remote diagnostics to deliver lower power use, higher availability, and scalable capacity for municipal and industrial water treatment.
• For instance, in October 2026, Xylem said more than 40 wastewater treatment plants in Europe are operating or preparing to operate WEDECO ozone generators for micropollutant removal, including Zürich’s Werdhölzli plant, and introduced its WEDECO Evotide platform for drinking water, micropollutant removal, and water reuse
• Manufacturers are developing modular generators with built-in redundancy, high-efficiency electrodes, and optimized power supplies that reduce energy use per kilogram of ozone and allow utilities to scale capacity as treatment requirements grow.
• Hybrid processes, such as ozone combined with activated carbon, biological filtration, UV, or hydrogen peroxide, are also gaining attention as treatment plants seek to remove pharmaceuticals, color, and trace organics while controlling by-products.
• For instance, in September 2026, Faraday Ozone officially introduced its OB Series ozone generators at IFAT India 2026 in Mumbai. The company highlighted its high-capacity ozone generation technology, IoT integration, compact design, and applications in industrial effluent treatment, reverse osmosis, tertiary treatment, water reuse, and advanced oxidation processes. The company announced production capacity of up to 5,000 g/hour from a single machine.
• As electrode efficiency, oxygen supply integration, and real-time monitoring continue to advance, ozone generation is expected to move beyond conventional disinfection into precision oxidation systems for micropollutant removal, water reuse, and chemical-free industrial processing.

What are the Key Drivers of the Ozone Generation Market?

• The growing need for safe drinking water and advanced wastewater treatment, driven by tightening discharge standards and concern over micropollutants, has significantly increased demand for chemical-free oxidation and disinfection technologies such as ozone.
• For instance, in May 2026, Salher announced the launch of its new OZW ozone generation product range for water and air treatment. The portfolio includes three product lines: OZW CORE for smaller applications, OZW PRO for medium-capacity installations, and OZW MAX for industrial-scale applications. The systems incorporate features such as automatic controls, oxygen supply, ozone monitoring, and corona discharge technology.
• Utilities, food processors, healthcare facilities, and industrial plants are adopting ozone systems to reduce reliance on chlorine and other chemical disinfectants while improving color, odor, and organic contaminant removal.
• For instance, in July 2026, Onza Corp launched FreshSure, a crystallized ozone sachet technology designed for food safety and preservation. The company describes the product as a solid-format ozone solution intended to provide antimicrobial protection and extend produce freshness throughout the food supply chain. The technology was undergoing trials with agricultural and food producers in three countries.
• With growing water scarcity and reuse requirements, ozone can break down contaminants without leaving harmful residues, and it can be integrated easily with existing filtration and biological treatment stages.

What Factors are Challenging the Growth of the Ozone Generation Market?

• Ozone generation requires large quantities of electricity and, in many systems, oxygen supply and cooling water, so energy consumption and capital costs can be high compared with conventional disinfection methods.
• For instance, in May 2026, according to RSC Advances, a review noted that large-scale and long-term use of ozone is often limited by high energy use, formation of unwanted oxidation by-products, operational and occupational safety issues, and restrictive regulatory standards.
• Ozone is toxic at elevated concentrations and decomposes quickly, so facilities must invest in off-gas destruction, leak detection, ambient monitoring, and operator training, which add complexity and compliance costs.
• In addition, bromate formation in bromide-containing waters and the creation of transformation products can require extra post-treatment steps, such as biological filtration or activated carbon, increasing system footprint and operating expenses.
• For instance, in May 2026, according to the journal Catalysts, a critical review of non-radical catalytic ozonation for wastewater treatment examined bromate trade-offs and scale-up constraints, highlighting that real-wastewater performance and by-product risks remain important barriers to wider deployment of ozone-based treatment in full-scale wastewater plants across varied water matrices.
• The combination of high energy demand, by-product management, safety requirements, and competition from UV, chlorination, and activated carbon can restrain adoption among small utilities and cost-sensitive industrial users, particularly in developing markets.
