Stricter Wastewater-Discharge Regulations
Mandates that lower allowable disinfection byproducts in treated effluent push utilities toward ozone because the molecule inactivates pathogens without forming trihalomethanes or chloramines.[1]United States Environmental Protection Agency, “Stage 2 Disinfectants and Disinfection Byproducts Rule,” epa.gov Updated Chinese quotas on ozone-depleting substances clarify compliance and indirectly stimulate local demand for ozone systems, especially in petrochemical and pharmaceutical complexes requiring advanced oxidation for refractory pollutants.[2]Government of China, “Regulations on Ozone-Depleting Substances Management,” gov.cn As facilities retrofit aging chlorination lines, corona discharge units offer drop-in replacements that meet multibarrier treatment targets under variable flow conditions.
Growing Urban Water-Scarcity & Reuse Projects
Roughly 2.7 billion people live with water scarcity each year, and 44% of municipal wastewater runs untreated, prompting megacities to adopt multi-barrier treatment trains that integrate ozone ahead of biologically activated carbon filters. Ozone’s 3,000-times faster disinfection kinetics versus chlorine allow compact reactors that fit space-constrained plants while leaving no harmful residuals, a decisive advantage for direct potable reuse programs. With only 277 U.S. plants producing ozone today out of an estimated 150,000 municipal facilities, untapped municipal potential remains large.
Post-COVID Demand for Safe Air Purification in Buildings
Commercial operators continue installing ozone-ready HVAC coils to neutralize airborne bacteria and odors without expendable filters, evidenced by Dubai International Airport’s large-scale deployment that cut odor-control costs while keeping indoor ozone below the 0.1 ppm OSHA limit. Gaming halls and hospitality venues replicate the model, leveraging real-time sensors and variable-frequency corona modules that match ozone output to occupancy levels. Controlled low-dose cycles achieve 3-log reductions of multidrug-resistant bacteria within minutes, supporting infection-control protocols in healthcare and senior-living facilities.
Resonant High-Voltage Power Supplies Reduce OPEX
Next-generation resonant inverters raise electrical efficiency to 120 g kWh versus 80 g kWh in legacy setups, trimming operating costs by 25-30%, a compelling proposition in regions with high electricity tariffs or carbon pricing. Precision pulsing also minimizes unwanted bromate formation in high-bromide source waters, easing regulatory approvals and broadening addressable markets.

High CAPEX & OPEX Versus UV or Chlorine
Corona discharge skids require high-grade stainless piping, precision oxygen feed equipment, and chillers, raising turnkey costs by USD 0.16 per m³ above chlorination in 100 m³ day plants.[3]Government of Newfoundland and Labrador, “Cost Comparison of Disinfection Options for Small Water Systems,” gov.nl.ca Skilled staff must maintain dielectric gaps and calibrate ozone analyzers, further stretching budgets in small utilities. Nonetheless, total cost curves improve under disinfection byproduct penalties, nudging medium-sized municipalities toward hybrid ozone-biofiltration trains.
Worker-Safety Concerns Over In-Situ O₃ Exposure
OSHA fixes an 8-hour permissible exposure limit at 0.1 ppm, and EPA flags ground-level ozone above 0.070 ppm as pollution, compelling operators to install distributed gas detectors and interlock systems that vent units at defined thresholds. These safety upgrades add capital outlays and constrain retrofits in tight mechanical rooms lacking adequate ventilation.
Segment Analysis
By Technology: Corona Discharge Dominance Faces Electrolytic Challenge
Corona discharge held a 57.7% ozone generation market share in 2024, anchored by proven scalability in large municipal and petrochemical plants. High-dielectric barrier reactors with medical-grade oxygen reliably deliver 12% weight ozone at flow rates topping 500 ppd, satisfying stringent pathogen-removal credits. Cooling jackets and moisture control systems raise complexity, yet lifetime cost advantages persist when plants exceed 2 mgd throughput. The rapid uptake of resonant inverters boosts gram-per-kilowatt productivity, narrowing OPEX gaps with UV.
Electrolytic designs are forecast to register a 9.6% CAGR, riding demand for compact, point-of-use disinfection units in food service and healthcare. Proton-exchange membrane stacks paired with boron-doped diamond anodes produce up to 2.2 mg L⁻¹ at 1 A for 20 hours without performance loss, opening semiconductor wet-bench and ultrapure rinse applications CHEMRXIV.ORG. Lifespan constraints on BDD electrodes and higher kWh kg cost currently restrain broad adoption, but localized manufacturing initiatives reduce supply risk.

By Application: Water Treatment Leadership Challenged by Food Processing Growth
Water treatment commanded 55.9% of the ozone generation market size in 2024 on the back of 277 U.S. plants alone collectively producing more than 600,000 lb day. Advanced oxidation trains pairing ozone with hydrogen peroxide or UV achieve near-complete degradation of pharmaceuticals and endocrine disruptors at residence times under 10 minutes. Growing membrane fouling concerns further elevate ozone pretreatment desirability because short oxidation boosts flux recovery without chemical clean-in-place reagents.
Food processors are expected to grow 8.9% CAGR through 2030 as clean-label initiatives gain momentum. GRAS-recognized ozonated water cuts chemical sanitizer loads, slashes rinse volumes, and extends the shelf life of fresh produce by up to 97.5% mold reduction in citrus test runs. Craft breweries deploy micro-ozonation for keg sanitation and odor-free pipeline flushing, lowering respiratory hazards linked to peracetic acid exposure. These hygiene gains feed adoption beyond premium categories into mainstream dairy and meat plants.
By End-User Industry: Municipal Strength Meets Residential Acceleration
Municipal utility boards retained a 46.0% share of the ozone generation market in 2024, thanks to predictable capital budgets and regulatory pushes to cut disinfection byproducts. Ozone’s proven Cryptosporidium log-reduction credit and strong taste-and-odor control justify system retrofits in cities such as Grand Forks, North Dakota, where two 500 ppd Wedeco SMOevo units went online in 2024.
Residential adoption is projected to increase at an 8.3% CAGR as countertop electrolytic units reach big-box retail shelves. Consumers looking to improve indoor air quality use plug-in ozone diffusers with sensors that maintain safe parts-per-billion ranges. In parallel, aquaculture farms and semiconductor fabs broaden the industrial user base. Nanobubble generators deliver 90% bacterial reductions in intensive ponds, while ultrapure rinse modules in advanced logic fabs demand in-situ electrolytic ozone with low total organic carbon content.
