PSA Oxygen Generator For Fish Farming

As the population grows, the demand for aquatic products rises, and aquaculture develops. Due to overfishing, fishery resources are depleted, and aquaculture has become an important way to meet demand. Various breeding facilities are spread across ponds, rivers, breeding pools and offshore waters. The key to successful aquaculture is high dissolved oxygen concentration in the water, which can promote the growth of aquatic animals and enhance immunity. Artificial oxygen production equipment can break through the limitations of natural conditions and provide a stable oxygen supply, laying the foundation for high and stable production. The psa oxygen generator we developed is suitable for various aquaculture scenarios, can provide oxygen production solutions, meet different oxygen production needs, and help the development of the aquaculture industry.

The Significance of Oxygen in Fish Farming

Fish rely on dissolved oxygen in the water to breathe, and once there is insufficient dissolved oxygen in the water, serious problems will arise. Low oxygen will put fish under survival pressure, reduce their activity and willingness to eat, and slow their growth rate because nutrient absorption and utilization are restricted. At the same time, fish immunity is weakened, white blood cell activity is reduced, and it is difficult to resist pathogens. When the disease breaks out, the condition is prone to worsen, which may lead to large-scale deaths and bring economic losses to farmers. Traditional farming relies on air and water contact and aquatic plant photosynthesis to supplement oxygen, but in modern high-density farming, natural oxygen supplementation cannot meet the demand, and the contradiction is more prominent during high temperatures in summer. Therefore, maintaining sufficient and stable dissolved oxygen in the water is critical to the healthy development of fish farming. Equipped with artificial oxygenation equipment, such as high-efficiency oxygen generators, can solve the problem of insufficient dissolved oxygen and help achieve high and stable production.

How PSA Oxygen Generators Work

Principle Overview

The working principle of the PSA oxygen generator is to use the difference in the adsorption performance of specific molecular sieve materials for oxygen and nitrogen. Under certain pressure conditions, the molecular sieve can preferentially adsorb nitrogen and let oxygen pass through. This adsorption process is reversible, and the adsorption of nitrogen and the release of oxygen can be achieved by changing the pressure.

Adsorption process

The air is first filtered through the air intake filter device and then enters the compressor for supercharging. The supercharged air enters the molecular sieve adsorption tower, where nitrogen is adsorbed by the molecular sieve, while oxygen passes through the molecular sieve smoothly to the next stage. In this process, moisture, carbon dioxide and other impurities are also removed.

Regeneration process

When the adsorbent in the molecular sieve adsorption tower reaches saturation, it is necessary to discharge the adsorbed nitrogen and other impurities into the atmosphere through a switching valve to regenerate the adsorbent. This process is usually carried out at a lower pressure to desorb the adsorbed gas.

Oxygen purification and supply

In the PSA oxygen generator, after the oxygen is initially separated by the molecular sieve, it will be further concentrated through the fine sieve tower. Then, the oxygen is regulated by the flow control valve, moistened by the humidified water tank, and finally flows through the oxygen supply pipe for oxygen supply. In this way, the PSA oxygen concentrator can continuously provide high-purity oxygen.

Advantages of PSA Oxygen Generators for Fish Farming

Reliable oxygen supply: PSA oxygen generators provide a stable and reliable oxygen supply, which is not affected by external factors such as weather and can operate continuously, ensuring the oxygen needs of fish during critical periods such as fish spawning or low dissolved oxygen in summer.

Cost-effective: In the long run, it has low energy consumption, long molecular sieve life, and reduces replacement frequency and cost. Maintaining appropriate dissolved oxygen can also promote the healthy growth of fish and improve the overall production capacity and profitability of the farm.

Customizable output: Different oxygen production can be customized according to the scale of the farm and the oxygen demand of the fish species.

Easy operation and maintenance: The operation is user-friendly and often equipped with automatic control to adjust the oxygen production according to the dissolved oxygen in the water. Maintenance is also relatively simple. Regularly checking the pressure, molecular sieve condition and compressor performance can ensure stable operation of the equipment.
