Environmental Industry
Aqua Oxygen Supply System AOSS
Core Values of AOSS for Environmental Industries
AOSS is committed to using the power of oxygen to improve various industrial environments in an eco-friendly
way. By expanding the application of its multi-purpose oxygen supply system to areas like water quality
improvement and wastewater purification, AOSS aims to contribute to environmental sustainability.
- Versatility
- Carbon Neutrality
- Wide Range of Applications
Eco-Friendly Industrial Oxygen Supply System
AOSS promotes growth, activation, and purification in various environments by applying the diverse
benefits of oxygen. It maintains vitality in fish tanks, reducing mortality rates, and enhances crop growth,
increasing yields. When applied in livestock farms and purification facilities, it reduces odors and
purifies wastewater, expanding its role as an eco-friendly environmental improvement system.

Safe and Convenient Automatic Oxygen Supply System
This system replaces traditional methods that relied on liquefied or gaseous oxygen to increase dissolved
oxygen (DO) levels. It eliminates the need for cumbersome cylinder refills and replacements, instead providing
a continuous supply of oxygen from an on-demand generation system, ensuring safety and convenience.
- Air Intake and
Nitrogen Separation - The oxygen generator
separates oxygen and
nitrogen from the air.
- Oxygen
Extraction - The separated oxygen is
filtered and delivered
through piping.
- Oxygen Supply to Fish
Farms or Aquariums - The oxygen is supplied to
fish through stones connected
to the piping system.
- Oxygen Supply Process
1 Air Intake and Nitrogen Separation
The oxygen generator separates oxygen and nitrogen from the air.
2 Oxygen Extraction
The separated oxygen is filtered and delivered through piping.
3 Oxygen Supply to Fish Farms or Aquariums
The oxygen is supplied to fish through stones connected to the piping system.
