Water Treatment Ozone Generator Market Opportunity, Growth Drivers, Industry Trend Analysis, and Forecast 2025 - 2034

The Global Water Treatment Ozone Generator Market, valued at USD 101.1 million in 2024, is set to experience substantial growth with a projected compound annual growth rate (CAGR) of 7.7% from 2025 to 2034. These ozone generators produce ozone (O3), a highly effective oxidizing agent crucial for water disinfection and purification. Ozone is known for its superior ability to eliminate bacteria, viruses, and organic contaminants, all while improving water clarity and safety. Unlike traditional chlorine-based methods, ozone treatment produces no harmful byproducts, making it a safer, environmentally friendly alternative for water purification.

A key driver behind the growing demand for ozone generators is the increasing need for water treatment solutions that reduce harmful disinfection byproducts (DBPs), such as trihalomethanes (THMs) and haloacetic acids (HAAs), which are commonly associated with chlorine. Ozone technology is a powerful tool in overcoming these regulatory challenges, offering a cleaner, safer option for disinfecting water. The ability of ozone generators to enhance water quality and provide an environmentally sustainable solution is fueling their adoption across various industries.

The market for ozone generators is also expanding due to the technology’s versatility in several applications, including municipal water treatment, wastewater recycling, and industrial effluent treatment. As the global demand for clean, safe water intensifies across multiple sectors, ozone generators are increasingly being seen as a viable solution for tackling water contamination, further accelerating market growth. The continuous need for water treatment innovations that improve both safety and efficiency is expected to sustain the upward market trajectory.

The ozone generator market is divided by technology, with key segments including ultraviolet (UV), cold plasma, corona discharge, and electrolytic methods. The corona discharge technology, in particular, is anticipated to dominate the market, reaching USD 74 million by 2034. Known for its high ozone output and efficiency, this method is particularly suitable for large-scale water treatment systems. Its versatility makes it ideal for a wide range of installations, from residential to municipal and industrial applications, which will further drive its adoption globally.

In terms of application, the water treatment ozone generator market is segmented into industrial process water treatment, municipal water treatment, and other sectors. The municipal water treatment segment is expected to grow at an impressive CAGR of 8.2% through 2034. As municipalities face increasing pressure to adopt advanced disinfection methods, ozone generators are becoming a go-to solution. These systems offer superior performance in eliminating harmful microorganisms and contaminants, delivering more efficient and safer results than traditional chlorine disinfection.

In the U.S., the water treatment ozone generator market is projected to reach USD 55 million by 2034. This growth is largely driven by stringent water quality regulations such as the Safe Drinking Water Act and Clean Water Act, which mandate effective pathogen and pollutant removal. Additionally, continued investments in upgrading municipal water treatment infrastructure will further propel the adoption of ozone generators. These technologies are essential in meeting modern demands for efficiency, safety, and regulatory compliance, positioning them as a key component in the future of U.S. water treatment solutions.
