1. Introduction

Fish and shrimp farms have come to rely on a stable level of dissolved oxygen to maintain high growth rates and healthy animals. A [VPSA oxygen plant] can provide a continuous supply of high-purity oxygen directly to the aquaculture ponds to keep oxygen levels high and let the fish grow stronger, faster with lower mortality.

2. Why Aquaculture Needs On-Site Oxygen

* Oxygen levels below 5 mg/L in water stress fish, slowing their metabolism.

* Transported and stored liquid oxygen cylinders are expensive, unreliable.

* On-site oxygen generation ensures 24/7 reliable oxygen, even during peak biomass growth or unusually hot weather.

3. What Is a VPSA Oxygen Plant

A VPSA (vacuum pressure swing adsorption) oxygen plant separates the nitrogen from ambient air to provide 90–95% pure oxygen that is ideal for use in [aquaculture oxygenation] .

4. Product Description & Working Principle

* Twin adsorption columns filled with molecular sieve material

* Blower, vacuum pump, and PLC controller

* Automatic column switching to provide continuous output

* Ambient air flows through the molecular sieves, which adsorb nitrogen and release it into the atmosphere to produce clean oxygen for injection into the aquaculture pond

5. Smart Features for Fish Farming

* IoT Monitoring: Track dissolved-oxygen levels remotely and receive instant alerts when thresholds are crossed

* AI Control: Automatically modulates oxygen flow based on fish biomass, temperature, time of day

* Energy Optimization: Smart load management to reduce power consumption

6. Technical Details

l Purity: 90–95%

l Flow Rate: 5–500 Nm³/h

l Pressure: 0.1–0.5 MPa

l Power: 3–50 kW

7. Innovative Advantages

* Can reduce the feed conversion ratio (FCR) by as much as 15%

* Less disease risk from consistently optimal water quality

* Works with [recirculating aquaculture systems (RAS)] for closed-loop farming

8. Environmental & Economic Benefits

* 30% lower operating cost compared to delivered liquid oxygen cylinders

* Recyclable components to ensure a low-carbon footprint

* Allows for less chemical treatment and a more sustainable operation

9. Real-World Case Study

A tilapia farm in Peru purchased a 100 Nm³/h [VPSA oxygen generator] to save on feed costs and boost growth rate. Within six months, they were able to improve growth rate by 20% and reduce mortality by 25%.

10. Applications

* Intensive fish aquaculture (salmon, tilapia, catfish, etc.)

* Shrimp hatcheries, nursery ponds

* [RAS aquaculture] facilities

* Emergency supply during algal blooms or other oxygen depleting events

11. FAQs

Q1: How often must the molecular sieve be replaced?

A: Every 3–5 years, depending on air quality.

Q2: Can this system run 24/7?

A: Yes, it is designed for continuous use in aquaculture operations with minimal maintenance.
