Executive Summary: Solving Chemical-Free Disinfection and Water Treatment Challenges
Global Leading Market Research Publisher QYResearch announces the release of its latest report “Ozone Generation Technology – Global Market Share and Ranking, Overall Sales and Demand Forecast 2026-2032″. For water treatment facilities, pharmaceutical manufacturers, medical device sterilizers, and industrial processors, effective disinfection without chemical residues presents persistent operational and regulatory challenges. Traditional chemical disinfectants (chlorine, chloramine, hydrogen peroxide) leave byproducts (trihalomethanes, chlorates) subject to strict environmental regulations, require chemical storage and handling with associated safety risks, and can corrode equipment. Ozone generation technology addresses these challenges through ozone generators that work by combining oxygen (O2) with energy to produce ozone (O3)—a powerful oxidizing agent that decomposes to oxygen without residues—making it ideal for applications requiring high-purity disinfection without chemical additives. In this report, we focus on electrolytic ozone generators, which produce ozone directly from water without feed-gas preparation, offering advantages in purity and compactness over corona discharge alternatives.
Based on current market conditions, historical analysis (2021-2025) and forecast calculations (2026-2032), this report provides a comprehensive analysis of the global ozone generation technology market, including market size, share, demand, industry development status, and forecasts for the next several years. The global market was valued at US$ 19.6 million in 2024 and is forecast to reach a readjusted size of US$ 26.4 million by 2031, growing at a compound annual growth rate (CAGR) of 4.4% during the forecast period 2025-2031. Suez, De Nora Permelec Ltd, and BWT Pharma & Biotech are the top three players in ozone generation technology, with approximately 56% combined market share.

Product Definition: Electrolytic Ozone Generation Principles
Ozone generation technology produces ozone (O3) by exposing oxygen molecules (O2) to energy, breaking the two atoms apart. The single oxygen atoms quickly bond in groups of three to form ozone. While commercial ozone generators historically used corona discharge (high-voltage electrical discharge through oxygen or air), this report focuses on electrolytic ozone generators—a more specialized technology producing ozone directly from water via electrochemical cells.
Electrolytic ozone generation technology uses a proton exchange membrane (PEM) cell with specialized electrodes (typically platinum-coated titanium or boron-doped diamond). When deionized water flows through the cell and voltage is applied, water molecules are split at the anode to produce ozone (O3), oxygen (O2), and hydrogen ions (H+). The hydrogen ions migrate through the membrane to the cathode, where they combine with electrons to form hydrogen gas (H2). Electrolytic ozone generation technology offers several advantages: ozone is produced directly from water without compressed air or oxygen feed-gas preparation; ozone purity is extremely high (no nitrogen oxides or other corona discharge byproducts); and systems are compact, quiet, and operate at low voltage.
Market Segmentation by Output Capacity: Less than 3g/h, 3g/h-9g/h, and More than 9g/h
The ozone generation technology market is segmented by ozone output capacity (grams per hour) into three tiers: less than 3g/h, 3g/h-9g/h, and more than 9g/h.
Less than 3g/h Ozone Generation Technology
Small-scale ozone generation technology (under 3g/h output) serves point-of-use water treatment applications including pharmaceutical water purification (WFI—Water for Injection, purified water storage tanks), medical device sterilization (endoscope reprocessors, dental unit water lines), laboratory water systems, and small commercial disinfection. A representative user case from Q1 2026 involved a hospital central sterile supply department (CSSD) installing an electrolytic ozone generator (2g/h) for endoscopic instrument reprocessing. The ozone system replaced peracetic acid-based disinfectant, reducing chemical procurement costs by US$ 15,000 annually and eliminating worker exposure to concentrated chemical fumes. The system achieved log-6 reduction (99.9999%) of bacterial spores in 15-minute cycles, meeting FDA 510(k) clearance requirements.
3g/h-9g/h Ozone Generation Technology
Mid-range ozone generation technology (3-9g/h output) serves industrial water treatment for pharmaceutical manufacturing (sanitization of reverse osmosis systems and storage/distribution loops), food and beverage processing (bottle rinsing, produce washing, CIP sanitization), and semiconductor manufacturing (ultrapure water polishing). A technical challenge for mid-range ozone generation technology is managing hydrogen off-gas (produced at the cathode in electrolytic cells). Hydrogen accumulation poses explosion risks in enclosed spaces. Leading systems incorporate catalytic converters (recombining H2 with O2 to form water) or forced-air ventilation with hydrogen sensors interlocked to ozone generator controls.
More than 9g/h Ozone Generation Technology
Large-scale ozone generation technology (over 9g/h output) serves municipal water treatment (disinfection of drinking water and wastewater), industrial cooling towers (biofilm control without chemical biocides), and large pharmaceutical water systems (multi-loop WFI distribution). Suez and De Nora Permelec dominate this segment, supplying electrolytic ozone generation technology to major water utilities and pharmaceutical plants globally. An exclusive industry observation from Q2 2026 reveals that large-scale ozone generation technology adoption is accelerating in regions with stringent disinfection byproduct regulations (EU Drinking Water Directive recast, US EPA Stage 2 DBP Rule), as ozone produces no regulated trihalomethanes or haloacetic acids.
Market Segmentation by Application: Medical Application, Industrial Application, and Others
Medical Application
Medical applications for ozone generation technology represent the largest segment (approximately 40-45% of market revenue), driven by pharmaceutical water purification (WFI systems require sanitization without chemical residues) and medical device sterilization (endoscopes, surgical instruments, dental equipment). A policy development from March 2026: The European Pharmacopoeia (Ph. Eur.) updated its monograph for Water for Injection (WFI) to permit non-thermal sanitization methods (including ozone) at the point of use, recognizing ozone generation technology as equivalent to heat sanitization for WFI storage and distribution systems. This regulatory change is expected to increase adoption of electrolytic ozone generators in European pharmaceutical manufacturing.
Industrial Application
Industrial applications for ozone generation technology include food and beverage processing (disinfection of bottled water, juice pasteurization, produce washing), semiconductor manufacturing (ultrapure water polishing), and cooling tower water treatment (biofilm control, Legionella prevention). A representative user case from Q2 2026 involved a beverage bottling plant replacing chlorine dioxide with ozone generation technology for bottle rinsing (pre-fill sanitization). The ozone system reduced chemical handling risks (no concentrated chlorine dioxide storage), eliminated chlorine off-flavor complaints (zero detectable residuals in finished product), and reduced wastewater treatment costs (ozone decomposes to oxygen, no residual chlorine requiring neutralization).
Industry Development Characteristics: Electrolytic vs. Corona Discharge
The ozone generation technology market is characterized by three major trends. First, the shift from corona discharge to electrolytic ozone generation technology continues in high-purity applications (pharmaceuticals, medical devices, electronics) where nitrogen oxide (NOx) byproducts from corona discharge are unacceptable. Electrolytic systems produce ozone with no NOx or other gaseous byproducts, achieving ozone purity exceeding 98%.
Second, integration with IoT and remote monitoring is enabling predictive maintenance and performance optimization for ozone generation technology systems. Sensors track cell voltage (increasing voltage indicates electrode scaling or membrane degradation), water flow rate, and ozone concentration, alerting operators before failure.
Third, the market remains highly concentrated, with Suez, De Nora Permelec, and BWT Pharma & Biotech holding approximately 56% combined share, reflecting the technical barriers to electrolytic cell manufacturing (proprietary electrode coatings, membrane assembly expertise, and water quality management).
Competitive Landscape
The ozone generation technology market features a concentrated competitive landscape of specialized electrochemical and water treatment companies. Key players identified in the full report include: Suez (France), De Nora Permelec Ltd (Italy/Japan), BWT Pharma & Biotech (Germany), Biowell (China), Innovatec (Italy), Jinhua (China), and Taikang Environment (China).
