Aquaculture aeration and blower sizing calculator.
Estimate an air-flow and blower-power screen from biomass, oxygen-demand assumption and equipment efficiencies.
Aquaculture aeration and blower sizing inputs
Planning tool only. Monitor water quality and animal behaviour, validate species-specific limits and follow the direction of a qualified aquaculture professional before changing stocking, feed, aeration or water chemistry.
Method: Oxygen demand is biomass multiplied by the entered demand rate. Required air flow uses oxygen content in air and the transfer efficiency you enter; power is an idealised efficiency screen.
Inputs used: Standing fish biomass = 500 kg; Planning oxygen demand = 0.3 g O₂/kg/h; Oxygen transfer efficiency = 15 %; Blower efficiency = 65 %
Assumptions: The result uses the values, units and options shown in the input snapshot.
Scope and warnings: Planning tool only. Monitor water quality and animal behaviour, validate species-specific limits and follow the direction of a qualified aquaculture professional before changing stocking, feed, aeration or water chemistry. Rounding and excluded real-world terms can make an external result differ.
How this aquaculture aeration and blower sizing calculator works
Oxygen demand is biomass multiplied by the entered demand rate. Required air flow uses oxygen content in air and the transfer efficiency you enter; power is an idealised efficiency screen.
A worked example
500 kg at 0.3 g O₂/kg/h has a 150 g O₂/h planning demand before transfer losses.
Does it select a blower?
No. Transfer efficiency changes by diffuser, depth, fouling, temperature and installation. Size redundancy, piping, back-pressure and emergency power with an aquaculture professional.
Calculations run on your device. Review your results before exporting or sharing them.
Keep oxygen demand and oxygen transfer separate
Fish biomass drives the demand screen, while diffuser type, water depth and fouling affect how much oxygen actually transfers from supplied air.
Provide redundancy and outage protection. Final blower selection requires measured back-pressure, equipment curves, piping layout and a site-specific design.
