Aeration Systems for Aquaculture — Buyer's Knowledge Page
Aeration keeps commercial farms alive. Choose aerators on Standard Aerator Efficiency (kg O₂/kWh) at your actual salinity, temperature and altitude — not the marketing datasheet.

Typische Anwendungen
- Shrimp and fish ponds (paddlewheel, splash, propeller-aspirator)
- Fine-bubble diffusers for intensive tanks
- Down-flow bubble contactors for high-DO RAS
Projektgrößen
- Small ponds: <20 HP
- Semi-intensive: 20–100 HP/ha
- Super-intensive: 100+ HP/ha
Auswahlkriterien
- kg-O₂/kWh at your operating salinity
- Depth and mixing pattern coverage
- Motor IP rating and marine corrosion class
- Noise, birds and biosecurity
Fragen, die Käufer stellen sollten
- What is the SAE / SOTR at my salinity?
- What HP/ha do you recommend and why?
- What is your mean time between failure in coastal conditions?
Häufige Beschaffungsfehler
- Buying by HP without oxygen transfer data
- Ignoring altitude correction (0.15% loss per 100 m)
- Under-sizing emergency aeration
RFQ-Empfehlungen
- Tender against kg-O₂/hr required, not HP installed
- Require third-party SOTR test data
