In recent years, ozone disinfection and sterilization technology has been increasingly adopted by more and more countries. In the United States, Japan, and many European nations, it is already widely used in fields such as public facilities, food processing, pharmaceuticals, agriculture, and medicine. Compared with other disinfection and sterilization methods, ozone disinfection and sterilization boasts broad-spectrum efficacy, simple operation, no residual substances, and instantaneous sterilization. Moreover, it completely avoids the environmental and health hazards caused by chemical disinfectants—many of which even carry a potential carcinogenic risk—making it an ideal disinfection and sterilization method.

A comparison between ozone disinfection and traditional disinfection methods shows that ozone disinfection has earned high recognition across various industries in the market due to its outstanding performance.

The emergence of third-generation ozone technology—the PEM electrolysis ozone generation technology—has greatly expanded the application fields of ozone. This technology overcomes all the drawbacks of the traditional high-voltage corona method. The core electrode of the generator is non-consumable, resulting in low operating costs. Moreover, the ozone concentration produced by this technology is more than six times higher than that produced by the conventional high-voltage corona method. Importantly, the ozone generated contains neither nitrogen oxides nor volatile organic pollutants—substances identified by national environmental monitoring agencies—as a result, it is truly a low-carbon, energy-efficient, and environmentally friendly product. Consequently, its application scope is even broader, making it an inevitable trend in the development of ozone production technology.

Currently, the high-voltage corona discharge method is widely used in the market for ozone generation. This method uses air as the raw material and relies on a dielectric medium maintaining a specific discharge gap between two parallel high-voltage electrodes. When a high voltage is applied across these electrodes, the heat generated excites oxygen molecules in the air, causing them to collide and form ozone. The corona discharge method produces ozone using air as a gas source. Since air contains more than 78% nitrogen, under high-voltage conditions, nitrogen reacts with oxygen to form a new compound—nitrogen dioxide. Nitrogen dioxide is internationally recognized as a toxic substance and is one of the factors contributing to the development of cancer. Moreover, the high-voltage corona discharge technology also limits the possibility of producing high-concentration ozone; typically, the weight-based concentration of ozone produced by this method ranges from 1% to 3%.

The low-pressure electrolytic ozone generation technology uses solid-state noble-metal polymers as the electrolyte. By performing low-pressure electrolysis of water (H2O), oxygen is separated to produce ozone. The resulting ozone has a weight-based concentration as high as 18-20%, and the accompanying gas is pure oxygen, with absolutely no pollution. This method requires no additional auxiliary equipment or additives—only the addition of a pure water supply system is needed for stable operation. Moreover, the equipment itself is equipped with a circulating cooling function for its own pure water, so there’s no need to implement separate cooling measures. Low-pressure electrolysis does not generate electromagnetic interference or other types of disturbances, making it suitable for use in laboratories or environments with highly precise equipment.

The core electrode of the low-pressure electrolytic ozone generator is a non-consumable type operating at 3–5V, featuring low electrode wear and enabling continuous operation. Moreover, it poses no safety risks (high-voltage corona-type ozone technology typically operates at voltages above 1,000V). The gas produced by the low-pressure electrolytic ozone generator consists of 20% high-concentration ozone, which is used for air disinfection and sterilization, and 80% oxygen, which helps improve indoor environmental quality and increase the oxygen content of the air. This project fully complies with the requirements of Item 7—Resource and Environmental Technologies—of the “National Key Areas of High Technology Supported by the Ministry of Science and Technology, the Ministry of Finance, and the State Administration of Taxation,” specifically Article 4: “Technologies for Improving Local Air Quality and Controlling Pollution,” which includes “technologies for disinfecting and sterilizing, removing dust, purifying, and increasing the oxygen content of air in urban public facilities.”
