Application scenarios and benefit improvement
| Breeding stage | Dissolved oxygen demand | PSA oxygen generator solution |
|---|---|---|
| Early stage of seedling stocking | Avoid bubble disease (dissolved oxygen ≤ 8mg/L) | Intelligently adjust low-flow oxygen supply to stabilize the water environment. |
| Mid-stage of breeding | Ammonia nitrogen/salt rise period | Accelerate the decomposition of harmful substances and reduce the risk of disease. |
| Late stage of breeding | High feed rate, high pollution load | Continuous high-oxygen supply shortens the fattening cycle. |
Features & advantages
Features
Precise oxygen supply
In view of the "lurking bottom dwelling" characteristics of white shrimp, oxygen is directly delivered to the bottom of the pond through nano-aeration tubes to eliminate dissolved oxygen stratification and prevent problems such as floating heads and black gills.
All-weather stable operation
No fear of high temperature (tolerance ambient temperature ≤45℃) and humid environment, supporting 24-hour continuous oxygen supply in the late stage of breeding.
Multi-scenario adaptation
Compatible with seawater, freshwater and brackish water aquaculture ponds, and anti-corrosion design extends equipment life.
advantages
Dissolved oxygen uniformity
Better than impeller/waterwheel aerators, avoiding the problem of high dissolved oxygen at the edge of the pool and lack of oxygen at the bottom of the pool.
Noise control
Operating noise <60dB, reducing shrimp stress response.
Maintenance cost
No mechanical impeller loss, filter replacement cycle up to 6-12 months.
Comparison with traditional oxygenation methods
| Comparison items | PSA oxygen generator | Impeller/waterwheel aerator |
|---|---|---|
| Dissolved oxygen efficiency | Directly inject pure oxygen, rapid increase of dissolved oxygen | Relies on air diffusion, low efficiency |
| Applicable water depth | Uniform oxygenation at all water depths | Mainly surface aeration |
| Energy consumption and cost | Mainly electricity costs, low long-term costs | High mechanical loss, frequent maintenance |

FAQ
Q: What is the core value of PSA oxygen generator for shrimp farming?
A: Improve the breeding density and survival rate: By stably supplying high-purity oxygen (more than 93%), promote the development of shrimp fry and reduce deaths caused by hypoxia.
Improve water quality: inhibit the growth of harmful anaerobic microorganisms, reduce the risk of shrimp diseases, and purify the water body in combination with ozone generators.
Shorten the breeding cycle: sufficient dissolved oxygen accelerates metabolism, reduces feed costs and breeding risks.
Q: What are the key technical parameters of the equipment?
A: Oxygen purity: ≥90% to ensure effective oxygenation.
Output matching: Select the model according to the scale of the breeding pond (such as 15L, 30L, etc.), and the processing capacity of common industrial models can reach 3-3000Nm³/h.
Energy consumption and power: The main cost is power consumption, and attention should be paid to the energy efficiency ratio of the equipment. For example, some models are adapted to 220V/380V voltage.
Q: What are the maintenance and operation costs of the equipment?
A: Maintenance frequency: Usually only regular inspection of molecular sieve life (about 3-5 years) and filter replacement are required, and the automated design reduces manual intervention.
Operation cost: Mainly electricity costs, no liquid oxygen storage costs, and long-term use costs are lower than traditional oxygen supply methods.
Q:Does it support intelligent regulation?
A: The dissolved oxygen monitoring system can be integrated to automatically start and stop the oxygen generator according to real-time dissolved oxygen data, optimize energy consumption and reduce operation difficulty. Some equipment supports remote control and is suitable for IoT management.
Q:How is the environmental adaptability?
A: High altitude/low temperature environment: You need to choose an adapted model. Some models can ensure performance by adjusting the gas supply and insulation measures.
Anti-corrosion design: It is recommended to choose stainless steel or special coating models to cope with the high humidity in aquaculture environments.
