According to Market Research Future, the Ozone Generation Market was valued at USD 1.77 billion in 2024 and is projected to reach USD 2.98 billion by 2035, growing at a compound annual growth rate of 4.86 percent. Ozone generators produce one of the most powerful oxidants known—ozone—which destroys pathogens, removes odors, and breaks down organic contaminants. Unlike chlorine, ozone leaves no harmful residues, making it attractive for water treatment, air purification, and industrial processes where chemical-free disinfection is valued.
How Ozone Generation Works
Ozone is produced when oxygen molecules are split and recombine into three-atom ozone (O₃). Three technologies dominate: corona discharge, which passes oxygen through a high-voltage electrical field; ultraviolet light, which uses UV lamps to split oxygen molecules; and electrolytic generation, which produces ozone from water.
Corona discharge systems are most common for large-scale water treatment. UV systems suit smaller applications where simplicity matters. Electrolytic systems excel where dissolved ozone in water is required.
Applications
Water treatment represents the largest application. Municipal drinking water plants use ozone to eliminate pathogens and remove taste and odor compounds. Wastewater treatment uses ozone for disinfection and micropollutant removal.
Air treatment uses ozone generators to eliminate odors, pathogens, and volatile organic compounds in commercial buildings, hospitals, and industrial facilities.
Food processing uses ozone for sanitizing equipment, extending shelf life, and treating wash water.
