The fish in the production units consume oxygen from the water. In addition, there is a considerable discharge of food spill, feces and gases in water, all of which can have a harmful effect on the fish. With increasing reuse and recirculation of water – degassing of water become essential in order to keep the water quality at acceptable levels. The project idea of AquaDeGas is to develop a cost effective, reliable, robust, flexible, compact and efficient degassing method, which meets the needs of the aquaculture sector for removing oversaturated harmful gases, i.e carbon dioxide, nitrogen and argon. This will be made possible through development and application of ejector and nozzle technique for formation of micro-bubbles for effective gas exchange in water integrated with sensor- and control technology. The AquaDeGas project is funded under EC's Sixth Framework Program. Participants:
