AeroBoost airlift pumps provide a low-cost, decentralized approach to water reuse for aquaculture systems. These air lift pumps use air injection to circulate and aerate the water, allowing for increased fish production with less influent water. Mounted directly inside the culture tank, AeroBoost can be easily installed into existing systems or integrated into new designs.
Benefits of an Air Lift Pump
- • Reduces influent water use and effluent volumes
- • Reduces energy use relative to traditional water pumps
- • Increases rearing capacity without increased water use
- • Increases dissolved O2 and reduces dissolved CO2
- • Improves tank circulation and fish fitness
- • Reduces labor required to clean tanks
- • Increases production flexibility (unit may be moved to highest density tank)
- • Ideal for direct installation into new or existing circular tanks
AeroBoost Airlift Pump Features
- • Fish friendly design; no moving parts, noise, or vibration
- • Mounts from tank wall without tank modification
- • Internal components are easy to access and clean
- • Durable aluminum construction
- • Screened intake and adjustable discharge vane
- • Configurable to suit tank rotation direction
- • May be operated from a centralized air supply
- • Multiple units may be used in larger tanks to fit production needs
- • Manufactured in North America with factory-direct service and support
Description of Operation
An air lift pump is a simple device that uses pressurized air injected in a column of water to pump water. Air is injected with a diffuser below the water surface. The bubbles generated reduce the density of the water, causing the water to rise with the bubbles. Higher density water rushes in from underneath to fill the void, effectively pumping water from high density to low density. While the primary purpose of an airlift is to generate flow, a secondary benefit is that the water is aerated in the process, adding oxygen and driving off carbon dioxide.
The AeroBoost CT airlift pump effectively replaces influent water by aerating and mixing the water in a circular tank. Its effectiveness increases the further the tank is operated from the saturation DO and DCO2 levels.
