Aquaculture
On-site oxygen generation for aquaculture operations requiring a continuous oxygen supply for pond or tank oxygen enrichment. System sizing should match oxygen demand, purity, pressure and operating conditions.
Recommended Equipment

PSA Oxygen Generator
ZMS twin-tower O₂ for aquaculture, wastewater aeration, metallurgy and combustion enhancement.

Centrifugal Pump
16 sub-series for water, wastewater, chemicals and multistage.
Key Selection Considerations
- Required oxygen flow — Establish the oxygen demand of the pond or tank first; the PSA oxygen series covers 1–200 Nm³/h, so the duty point must be calculated before a model is chosen.
- Target oxygen purity — The series produces 93% ±3% O₂. The set point follows from the dissolved-oxygen target of the process rather than being fixed in advance.
- Operating pressure — The series delivers 0.4–0.5 MPa; the required pressure depends on the injection depth and the pressure loss through diffusers and distribution pipework.
- Pond or tank demand and operating hours — Peak daily demand together with the number of operating hours determines whether a single skid or a modular arrangement is appropriate.
- Water circulation duty — Where pumps are used alongside the generator, define flow (0.75–10,000 m³/h) and head (2–1,800 m) from the pond layout and the required turnover rate.
- Site conditions and utilities — Ambient temperature, power supply, available footprint and the quality of the compressed-air feed all affect the final configuration.
Engineering Approach
Oxygen demand is calculated from the pond or tank volume and the target dissolved-oxygen level before any equipment is proposed. To raise a technical recommendation, send the required oxygen flow, target purity, injection depth or operating pressure, daily operating hours, power supply and ambient conditions.
Frequently Asked Questions
Why use a PSA oxygen generator in aquaculture?
PSA oxygen generation provides an on-site oxygen source that can reduce dependence on delivered oxygen and support continuous oxygen enrichment.
How is an aquaculture oxygen generator sized?
Estimate oxygen demand first, then specify required oxygen flow, purity, pressure, operating hours and site conditions.
What oxygen purity is normally required?
The standard range for this series is 93% ±3% O₂. The correct value should be set from the dissolved-oxygen target of the pond or tank rather than chosen in advance.
What operating pressure can be delivered?
The PSA oxygen series delivers 0.4–0.5 MPa. The required pressure follows from the injection depth and the pressure loss through diffusers and pipework.
Can one generator serve several ponds?
Depending on total oxygen demand and the distance between ponds, one unit can feed a distribution network. The demand profile and pressure loss should be checked before that is decided.
Are pumps required as well as a generator?
Some installations also require circulation or transfer pumps. In that case flow and head should be taken from the pond layout and the required turnover rate.
