At Moleaer Inc., we’re constantly looking for ways to help our partners improve their operations, reduce costs, and contribute to long-term sustainability. One of our most recent projects at Lødingen Fisk, an aquaculture facility in Norway housing over 1.7 million Atlantic salmon, shows how integrating Moleaer nanobubble technology into a well-optimized process can make a real difference. The RAS section at this facility was designed by AquaBioTech Group integrating Moleaer’s technology for Lødingen Fisk.
The results of this study were truly remarkable and I’m excited to share them with you.
With the integration of our Trinity Nanobubble Generator at Lødingen Fisk’s Recirculating Aquaculture System (RAS) and optimizing operating parameters, we saw significant improvements – not just in water quality, but in the efficiency of their biofilter and some very interesting observations related to the growth and welfare of their fish.
Boosting Oxygenation and Efficiency
Achieving efficient oxygen transfer is vital to the success of any aquaculture operation. Through years of research and fieldwork, we’ve developed a proprietary method for optimizing nanobubble concentration and ensuring the right conditions for key biological reactions to occur. It’s not just about adding nanobubbles—it’s about creating the right environment to maximize their impact.
At Lødingen Fisk, this meant reaching an Oxygen Transfer Efficiency (OTE) of 94%. This isn’t just a number—it represents better oxygen availability for fish, which supports their health and growth while maintaining cleaner water. For instance, dissolved oxygen levels rose by 23% and Oxidation-Reduction Potential (ORP) increased by 6.2%—both critical factors in creating an optimal environment for fish welfare.
Improved Water Quality and Biofilter Performance
Water quality is everything in aquaculture. At Lødingen Fisk, we saw a 30% reduction in water turbidity, resulting in a 67% decrease in ozone usage. Improved water clarity supports both fish health and operational efficiency, but the real standout was the performance of the biofilter. With nitrite accumulation reduced by 70% and ammonia nitrification rates up by 60%, the system could process waste more efficiently, providing a cleaner, safer environment for the fish.
These improvements aren’t just the result of introducing nanobubbles —they’re a reflection of how Moleaer’s system, when integrated into the facility’s operating conditions, can enhance overall performance.
Why Optimization is Key
What makes Moleaer’s approach unique is that we don’t just offer nanobubble technology – we’re delivering an integrated solution. Years of R&D and fieldwork have shown us that the real key to success in aquaculture is optimizing how nanobubbles are applied. It’s about creating the right environment, delivering the right technology, and having an intrinsic understanding of the systems’ functions and needs.
By fine-tuning these elements, we help facilities like Lødingen Fisk improve water quality, reduce operational costs, and boost production capacity.
For me, this study is a perfect example of how technology, when applied correctly, can make aquaculture more efficient, cost-effective and sustainable – there is a compelling economic argument for this type of technology.
