AeroBoost Airlift Pumps provide a low-cost, decentralized approach to water reuse for aquaculture systems. AeroBoost uses air injection to circulate and aerate the water, allowing for increased fish production with less Tinfluent water. The AeroBoost RC is designed specifically for raceway applications.
• Reduces influent water use and effluent volumes
• Ideal for direct installation into new or existing raceway tanks
• Increases rearing capacity without increased water use
• Increases dissolved O₂ and reduces dissolved CO₂
• Improves mixing for even water quality and better fish distribution
• Makes raceways self-cleaning; reduces labour
• Reduces energy use relative to traditional water pumps
• No reduction in raceway water level or rearing volume
• Fish friendly design; no moving parts, noise, or vibration
• Durable aluminum construction
• Both pump and baffle are easily removable to minimize impact to fish handling
• Internal components are easy to access and clean
• Standard and custom baffle mounting available to fit any raceway
• Adjustable spacing and baffle height to fit application needs
• Uses centralized air supply for multiple raceways
• Manufactured in North America with factory-direct service and support
Description of operation
An airlift is a simple device which 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. When used in a raceway with a baffle, the airlift pump provides improved flow dynamics, dissolved gas levels, and solids removal.
The AeroBoost RC system effectively replaces influent water by aerating and mixing the water in a raceway tank. The system improves mixing and increases flows rate in all installations. However, the gas transfer effectiveness increases the further the tank is operated from the saturation DO and DCO₂ levels.
