Nanobubbles lead to significant oxygen savings in salmon farms


Moleaer has tested its nanobubble technology with Grieg Seafood BC and CPI Equipment. The project, known as the CO²L Flow (pronounced cold flow) system, was led by Grieg using Moleaer’s patented nanobubble technology and CPI’s ODiN system, for the development of a salmon farming system in semi-closed confinement. Using Moleaer’s nanobubble generators resulted in a 75% reduction in oxygen consumption compared to existing technologies, according to a press release from the California-based company.

The generators work by injecting trillions of oxygen-rich nanobubbles into water supplies, increasing dissolved oxygen (DO) levels at the highest transfer efficiency and lowest cost, thereby reducing the operational expenses of salmon farms.

“We are committed to implementing long-term sustainable solutions to address some of the challenges we face as aquaculturists. Using Moleaer’s technology, we can safely deploy sea lice barriers up to 15 meters without compromising the mixing and dissolved oxygen levels inside the mesh enclosure. This is important to us, as maintaining optimal conditions within the new CO²L Flow System when the barriers are lowered is critical to the health and well-being of our fish,” said Dean Trethewey, production manager at seawater from Grieg Seafood, in a press release.

“Technology and innovation are the backbone of the aquaculture industry. We work closely with our customers, especially Grieg Seafood BC, to always listen to farmers’ problems and recommendations to improve our technology and create innovative solutions. Our latest collaboration with Moleaer’s nanobubble technology has been a huge success and, if deployed, will be a game-changer for other fish farming companies in all regions of the world,” said Kris McNichol, President of CPI Equipment.

“The aquaculture industry needs sustainable solutions that increase production without jeopardizing our environment. Our technology is unique because we provide nanobubbles with proven benefits in terms of reducing oxygen and energy costs, while cleaning up the environment and producing better water quality and higher fish production. said Nicholas Dyner, CEO of Moleaer.
