Calculateur de débit d'eau et d'oxygène RAS — estimation préliminaire
Le débit de conception est le plus élevé entre le débit porteur d'oxygène (demande ÷ baisse d'O₂ admise) et le débit de renouvellement. La demande part de l'aliment × kg d'O₂ par kg d'aliment ; le 0,25 proposé est une valeur publiée de planification modifiable.
Estimation préliminaire. Les résultats ne sont ni une conception, ni un devis, ni une prévision et doivent être revus par un ingénieur qualifié avant toute décision d'achat ou de financement.

Méthode et formules
Toutes les données sont les vôtres. L'outil ne contient ni rendements, ni survie, ni indice de conversion, ni prix, ni énergie, ni taux de financement.
- Demande O₂ (kg/j) = aliment (kg/j) × kg O₂ par kg d'aliment
- Débit oxygène (m³/h) = demande O₂ (kg/h) × 1 000 ÷ (O₂ entrée − O₂ sortie) [mg/L = g/m³]
- Débit de renouvellement (m³/h) = volume (m³) × renouvellements par heure
- TAN (kg/j) = aliment × part protéique × 0,092 (Timmons et Ebeling 2010)

How does FishMatch Group source suppliers for this requirement?
You submit one structured request. We translate it into a technical RFQ, run it against qualified manufacturers and integrators in the relevant categories, and return normalised quotations you can compare side by side on scope, lead time and total cost of ownership.
Do buyers see supplier names during the sourcing process?
No. Supplier identities stay confidential during discovery and evaluation. You receive anonymised, comparable technical and commercial packages, and introductions happen only after both sides are qualified and agree to proceed.
Before you request quotes
Equipment scope
What equipment does a commercial aquaculture project actually need?
A grow-out project typically needs holding infrastructure (tanks, ponds or cages), water movement (pumps, piping, valves), aeration or oxygenation, water treatment appropriate to the system, feeding equipment, grading and handling gear, monitoring and alarms, and backup power. RAS adds mechanical filtration, biofiltration, degassing, disinfection and tighter process control. Hatchery and processing scopes are specified separately.
Which equipment should be specified before requesting quotes?
Specify the items whose sizing changes everything downstream: design biomass and stocking density, water exchange or recirculation rate, oxygen demand at peak temperature, and installed pumping head. With those four fixed, suppliers can quote aeration, filtration, pumps and power on the same basis. FishMatch calculators produce these figures and attach them to the RFQ.
Can equipment be sourced in stages?
Yes, and phased procurement is common. The usual sequence is water supply and holding infrastructure, then aeration and treatment, then automation and monitoring, then processing and cold chain. Staging works when interfaces and capacity headroom are defined at the start; otherwise later phases force replacement rather than addition.
