For commercial aquaculture projects IAS offers a complete range of options for pure oxygen generation, ozone generation, gas diffusion, and off gassing. Speece cones, also called oxygenation cones and down-flow bubble contactors are highly efficient pressurized vessels that are effective for transferring pure oxygen or ozone into the process water stream to achieve high saturation rates. IAS offers oxygen and ozone generators to provide high purity gas for RAS systems. Off-gassing is an important process in recirculating aquaculture systems to keep CO2 within acceptable limits for optimal fish health. Choose from a wide range of options and capacities to meet your project requirements.
