FAQ
Q:What is the main role of PSA oxygen generator in sea bass farming?
A:PSA (pressure swing adsorption) oxygen generator separates high-purity oxygen by adsorbing nitrogen in the air, providing stable dissolved oxygen support for high-density breeding ponds. Its core functions include:
Maintaining dissolved oxygen levels in water: Sea bass has a high demand for dissolved oxygen (usually ≥5 mg/L), and PSA equipment can continuously supply oxygen 24 hours a day to avoid fish stress or death caused by lack of oxygen.
Increasing breeding density: Traditional oxygenation methods (such as impeller aerators) have limited efficiency. PSA systems can support higher-density breeding and increase unit output.
Q:Compared with traditional oxygen supply methods, what are the advantages of PSA technology?
A:PSA oxygen generators have the following significant advantages:
High efficiency and energy saving: Oxygen is separated by compressed air, and the energy consumption is lower than that of electrolyzed water or liquid oxygen transportation.
Automated control: Sensors can be integrated to monitor dissolved oxygen in real time, automatically adjust the oxygen supply, and reduce manual intervention.
Controllable purity: The oxygen purity can reach more than 90%, meeting the dissolved oxygen needs of different growth stages.
Q:How to choose the right PSA oxygen generator model according to the scale of aquaculture?
A:The following factors should be considered comprehensively when choosing:
Production demand: Small aquaculture ponds (such as 10 tons of water) can choose portable equipment with an oxygen production of 5-10 L/min; large farms (hundred tons) need to customize industrial-grade PSA systems (such as oxygen production ≥50 L/min).
Energy consumption and maintenance: Industrial-grade equipment needs to be equipped with a regulated power supply and regular molecular sieve replacement, and the maintenance cost is relatively high; small and medium-sized equipment pays more attention to energy efficiency.
Q:What matters need to be paid attention to in the operation and maintenance of PSA oxygen generators?
A:Key maintenance points include:
Air filtration: The front air filter needs to be cleaned regularly to prevent dust from clogging the molecular sieve.
Molecular sieve life: The adsorbent generally needs to be replaced every 2-3 years, depending on the frequency of use and ambient humidity.
System calibration: Regularly check the oxygen purity and flowmeter to ensure stable output.
Q:What is the specific impact of using PSA oxygen generators on the growth and aquaculture benefits of sea bass?
A:Practical applications show that:
Shorten the growth cycle: Stabilizing the dissolved oxygen environment can increase the feeding rate of sea bass and increase the average weight gain rate by 15%-20%.
Reducing mortality: The mortality rate caused by hypoxia has been reduced from 10% in the traditional model to less than 2%.
Fast cost recovery: Taking a farm with an annual output of 50 tons as an example, the investment in PSA equipment can be recovered through increased production and electricity saving within about 2 years.
