This transformation is also exhibited in the market's momentum. According to Persistence Market Research, the ozone technology market is projected to expand from US$1.7 billion in 2026 to US$2.7 billion by 2033, registering a 6.9% CAGR in the forecast period. These numbers signal a broad transition as ozone technology moves beyond its established role in water treatment to become a valuable solution for food preservation and a wide range of industrial applications.
Regulatory Standards Revolving around Clean Water to Boost Growth
Clean water is no longer just a public service. It has become a regulatory priority. As governments tighten water quality standards and utilities work to deliver safe drinking water, treatment technologies must do more than meet expectations. They must meet strict compliance requirements, and this is where ozone technology continues to stand out.
Water and wastewater treatment account for more than 45% of global ozone technology demand, making it the market's largest application. Unlike chlorine alone, ozone is highly effective against chlorine-resistant microorganisms such as Cryptosporidium and Giardia, which is why the U.S. Environmental Protection Agency (EPA) recognizes it as a primary disinfectant.
This growing regulatory focus is encouraging utilities to modernize their treatment infrastructure. Reflecting this trend, RainHarvest Systems launched its Pro Series and M Series ozone generators in April 2025. It introduced six new systems designed for residential, commercial, and industrial water purification with more precise dosing. The parallel growth of ozone systems and the water & wastewater treatment chemicals market highlights how integrated treatment solutions are becoming the foundation of modern water infrastructure.
Food Preservation is Emerging as the Next Growth Frontier
Water treatment remains ozone's largest application. But, the more interesting growth story right now is unfolding in food supply chains, where spoilage and contamination losses have become too costly for processors to treat as a packaging afterthought. The rising focus on food safety and shelf-life extension is also creating opportunities across related markets. Reflecting this momentum, the food preservative market is expected to climb from US$3.7 billion in 2026 to US$5.2 billion by 2033, a trajectory that tracks closely with how seriously the industry is now taking shelf-life extension.
Ozone has long been used in gas form for produce sanitation, but its instability made it difficult to store, ship, or dose consistently outside industrial settings, until recently. Denver-based AgTech start-up Onza Corp addressed this problem in July 2026 with the launch of FreshSure. It is described as the first commercially available crystallized ozone sachet, converting ozone from an unstable gas into a stable and extensible solid that food producers can use at every stage from farm to refrigerator. The product is designed to sit alongside existing cold-chain infrastructure rather than replace it, which is part of why the food cold chain market has become a natural adjacency for companies exploring what solid ozone can do next.
Smart Monitoring is Improving Ozone Performance
Ozone technology is no longer limited to generating and delivering ozone. It is becoming smarter through digital innovation. Modern ozone systems are now equipped with IoT sensors and AI-supported monitoring, enabling operators to track system performance, optimize ozone dosing, and identify maintenance needs before equipment failures occur. This improves operational efficiency, reduces downtime, and helps industries manage water treatment and food processing operations more effectively.
The benefits of smart ozone systems are also influencing related industries. As advanced ozone solutions help extend the freshness of fruits, vegetables, and other perishable products, demand is rising for packaging designed to support long shelf life. This is contributing to the growth of the fresh food packaging market, where manufacturers are developing packaging solutions that complement advanced preservation technologies.
What Lies Ahead for the Ozone Technology Market
The next growth phase for ozone technology will likely be driven by smart and sustainable solutions rather than conventional disinfection alone. As industries today adopt AI-enabled monitoring, automated process control, and energy-efficient ozone systems, the technology is evolving into an intelligent platform that improves operational efficiency while reducing costs and chemical usage. At the same time, expanding applications in food processing, healthcare, industrial sanitation, and wastewater reuse are creating new growth opportunities.
