Water Treatment Ozone Generator Market Size - By Technology, By Application, By End Use, Forecast, 2025 – 2034

Water Treatment Ozone Generator Market Size

The global water treatment ozone generator market size was valued at USD 101.1 million in 2024 and is estimated to grow at a CAGR of 7.7% from 2025 to 2034. These are devices designed to produce ozone (O2), a powerful oxidizing agent, for disinfecting and purifying water. In water treatment, ozone effectively eliminates bacteria, viruses, and organic contaminants, reduces chemical byproducts, and enhances water clarity and safety without leaving harmful residues.
 

Rising demand for generators with superior disinfection properties, capable of neutralizing a wide range of microorganisms, including bacteria, viruses, and protozoa present in municipal and industrial water will influence the product adoption. Growing global shift towards the adoption of environmentally sustainable water treatment practices will create lucrative opportunities for the product penetration.
 

Growing need for water treatment solutions that can minimize the formation of disinfection byproducts (DBPs) such as trihalomethanes (THMs) and haloacetic acids (HAAs), commonly with chlorine-based methods will complement the product adoption to reduce regulatory compliance issues and enhance the overall quality of treated water. Furthermore, increasing popularity of generators offering application versatility and effectiveness across diverse applications, including municipal water treatment, wastewater recycling, industrial effluent treatment, and even bottled water production will enhance the business outlook.
 

Water Treatment Ozone Generator Market Trends

Growing pressure on utilities and industries to adopt advanced water treatment technologies in line with rising public health initiatives advocating for the elimination of harmful pathogens and pollutants will accelerate the product growth. Furthermore, ongoing innovations in ozone generation technology, such as improved energy efficiency, compact designs, and automated control systems to make the product more reliable and cost-effective will further bolster the industry scenario.
 

Water Treatment Ozone Generator Market Analysis

Based on technology the market is segmented into ultraviolet, cold plasma, corona discharge, and electrolytic. The corona discharge segment is projected to cross USD 74 million by 2034. Rising demand for technology having high ozone product efficiency, particularly required in large-scale water treatment applications will accelerate corona discharge adoption. Growing inclination towards cost-effective technology, designed to cater to a wide range of capacities, from small-scale installations for residential water treatment to large-scale systems for municipal and industrial applications will uplift the business outlook.
 

Additionally, recent innovations in corona discharge technology, such as the use of advanced dielectric materials and energy-efficient designs to improve performance and reduce energy consumption will further drive the technology growth.
 

Based on application, the water treatment ozone generator market is segmented into municipal water treatment, industrial process water treatment and others. The municipal water treatment segment is set to grow at a CAGR of over 8.2% through 2034. Increasing need for generators with superior disinfection and oxidation properties, capable of effectively eliminating bacteria, viruses, and other microorganisms, surpassing the disinfection potential of chlorine will uplift the product adoption in municipal water treatment applications.
 

Increasing stringent regulatory frameworks, such as the Safe Drinking Water Act in the U.S. and European Union water directives, mandate advanced treatment methods to meet water quality standards, driving the product demand.
 

The U.S. water treatment ozone generator market is anticipated to reach USD 55 million by 2034. Rising stringent water quality standards including the Safe Drinking Water Act and Clean Water Act enforced for potable and wastewater quality will foster the product demand to remove pathogens and organic pollutants without leaving harmful residues. Growing investments in upgrading aging municipal water treatment plants to meet modern efficiency and safety demands will accelerate the incorporation of ozone generators, helping modernize treatment systems while ensuring compliance with regulatory standards.
 

In Asia Pacific, rapid urban growth and industrial expansion in countries such as India, China, and Southeast Asian nations led to increased water pollution, creating product demand to treat industrial effluents and municipal wastewater. Rising water scarcity in densely populated regions coupled with growing recycling initiatives to overcome the water requirement will propel the product adoption to remove contaminants, odor, and color, making recycled water safe for reuse.

Water Treatment Ozone Generator Industry News:

• In June 2023, the new headquarters of Bhopal Municipal Corporation (BMC) will feature an ozone generation plant for disinfecting and polishing treated water. The ozone treatment system, capable of producing 100 gms/hr, will include an oxygen generator, concentrator, venturi, pump, and ozone and oxygen pipes. This solution can also be applied to industrial waste, municipal water treatment, and other potable water uses.
   
• In April 2022, Toshiba teamed up with Larsen & Toubro Limited to supply three ozone generators to the Chandrawal Water Treatment Plant in Delhi. This initiative is a segment of the Delhi Water Supply Improvement Project, which is backed by JICA. Managed by the Delhi Jal Board, the project aims to upgrade the existing water treatment system with Toshiba's advanced ozonation technology. The setup will include three ozone generators, each boasting a capacity of 31 kg per hour. Notably, this installation stands out as one of the largest ozonation systems for water treatment in India.
