Nanobubble Benefits

The Power of Moleaer Nanobubbles: Proven Benefits in Aquaculture

Get Nanobubbles

Healthier Fish, Higher Quality

Nanobubbles help maintain a cleaner, oxygen-rich environment without added chemicals, improving feed conversion and reducing stress. This supports optimal conditions for fish growth, nutrition, and disease resistance, reducing reliance on medicinal treatments.

Efficient, Stable Oxygenation

Moleaer technology delivers over 85% oxygen transfer efficiency, ensuring stable oxygenation throughout the water volume in net pens, RAS systems, waiting cages, holding tanks, flow-through systems, and during fish crowding operations. This efficient transfer maximizes dissolved oxygen levels, creating optimal conditions for fish welfare and growth.

Enhanced Biofilter Efficiency, Cleaner Water

Nanobubbles enhance oxygen distribution, accelerating ammonia and nitrogen breakdown by delivering oxygen directly to the beneficial bacteria responsible for nitrification. The result? Improved biofilter efficiency, higher treatment capacity, and cleaner water – ensuring a healthier environment for fish.

Improved Cleaning and Mechanical Filtration

Nanobubbles help keep pipes clean through a scouring effect caused by their tiny size, surface charge, and hard shell, which reduce biofilm inside piping systems, creating healthier conditions for fish.

They also promote particle coagulation, allowing mechanical filtration systems to capture debris more efficiently. The result is cleaner, clearer water and a more effective filtration process.

Energy Savings and Reduced Carbon Footprint

Moleaer technology optimizes oxygen and energy use, reducing oxygen costs by up to 60%, cutting fuel consumption, and lowering greenhouse gas emissions from generators, compressors, and PSAs. This results in cost savings and more efficient resource use – all while supporting a more sustainable aquaculture operation.

Testimonials

What Our Customers Are Saying

Salmar Innovanor, Norway

“The summer months with high sea temperatures used to be a concern, but after installing Freya, we can fully utilize the capacity of the waiting cages even at high temperatures. With Freya installed on the waiting cages, we can crowd the fish more intensively without compromising fish welfare.”

“The Freya nanobubble generator has a large capacity and gives us quick results. After implementing the system, we’ve seen significant improvements in stress factors and find it easier to remove blood from the fish during processing.”

Thomas Godtliebsen

Manager of Waiting Cages

What Our Customers Are Saying

Australis Seafood, Chile

“After installing the Moleaer nanobubble generators, the CO2 inside the tank remains much more stable compared to the conventional system, and the fish appeared more relaxed.”

Jose Luis Requeros

Manager at the Australis Seafood Dumestre Plant
