Linde LLC featured its proprietary drop-in oxygenation system designed for easy handling and operation for intensive aquaculture, at the Seafood Expo North America. The new SOLVOX® DropIn system offers a simple solution for seawater species grown in sea cages, which are used throughout South America.
The oxygenation system is part of a family of SOLVOX pure oxygen-injection and diffusion systems that promote fish health throughout the growth cycle, and can boost dissolved oxygen (O2) levels much more efficiently than aeration systems, which require energy-intensive compressors.
The innovative drop-in oxygenation system (patent-pending) is ideal for high-value export species such as salmon, sea bass, sea bream, and arctic char. The SOLVOX DropIn oxygenation system contains a patented O2 dissolver and distribution system featuring a specially designed venturi nozzle.
After the unit is lowered to the desired depth, water is drawn in from below and mixed with O2. Oxygenated water is then distributed throughout the sea cage through the nozzles at the top of the unit. The system creates slow-rising microbubbles which extends O2 residence time. This, combined with the high surface-to-volume ratio of the rising bubbles, increases O2 dissolution efficiency even at low pressures.
