Pressure Swing Adsorption Technology
Pressure Swing Adsorption (PSA) is a gas separation technology. Its principle is based on the difference in the adsorption properties of different gas molecules by an adsorbent (such as zeolite molecular sieve), which allows the separation of gas mixtures. This technology uses air as the raw material and employs highly efficient, highly selective adsorbents to selectively adsorb nitrogen from the air, thereby achieving nitrogen-oxygen separation.

Environmental Protection
Oxygen plays a vital role in the field of environmental purification, especially in ozone generation. Oxygen is converted into ozone by electrical discharge or ultraviolet irradiation, a process that is widely used in water treatment and air purification because ozone is a powerful oxidizing agent that effectively decomposes organic matter in water, kills bacteria and viruses, and removes odors and noxious gases from the air. In addition, ozone is used in industrial wastewater treatment to degrade organic pollutants that are difficult to biodegrade.
Medical Oxygen Supply
Oxygen plays a key role in the medical oxygen supply industry, primarily used to support patients with respiratory deficiencies and to treat hypoxemia and various breathing disorders. It is widely used in operating rooms, emergency, intensive care units and wards, as well as in home care and telemedicine. Oxygen helps patients breathe more efficiently by increasing the level of oxygen in the blood and is an integral part of life-saving treatments and everyday medical care.
Aquaculture
Oxygen plays a vital role in the aquaculture industry, where it is used to maintain suitable levels of oxygen in the water column to ensure the healthy growth of fish and other aquatic organisms. By providing sufficient dissolved oxygen, oxygen helps prevent disease and mortality caused by low-oxygen environments, while promoting more efficient feed conversion rates and growth rates, resulting in increased farming efficiency and production. In addition, sufficient oxygen helps improve water quality and reduce the growth of harmful bacteria and pathogens, which is essential for maintaining a healthy and stable aquaculture environment.
