Degassing Towers
Degassing Tower Solution for Fish Farming and Aquaculture Applications
Pureflow Degassing Towers effectively strip harmful gases like carbon dioxide (CO₂) and nitrogen (N₂) from recirculating water. These towers enhance oxygenation, stabilize pH, and prevent gas supersaturation, ensuring optimal conditions for aquatic life. Built with corrosion-resistant materials such as FRP and PVC, they are suitable for marine and freshwater environments. The open-column design promotes high-efficiency gas exchange while maintaining low operational cost. Ideal for fish hatcheries, RAS facilities, and public aquariums, our degassing towers improve water quality, boost fish health, and increase overall system efficiency—making them a vital component in modern aquaculture engineering.
The Degas Tower receives the pre-filtered effluent wastewater and trickles it through aerated fixed bed solid media (PE bio balls), for nitrification and gas exchange – deaeration.
Biomedia is installed inside the Degas Towers to offer the maximum surface area not only for the microorganisms’ nitrification activity but also for the gas exchange process for restoring the levels of CO2 and O2 up to the required values.
Degas equipment design includes a service hatch on top, manway on the side, two grating layers to hold the biomedia packing volume stable inside the tower, level indicator, drain valve, and brackets for stilling well on the external sides of the Tower. The Unit is hydro tested prior to the second layer welding and at the end of production as a complete product.
