Norwegian Greentech (NGT), a supplier of high-efficiency water treatment and other water purification systems for use in the aquaculture industry, announced today that it will supply its UV- and filter-based water treatment system to Artic Seafarm's land-based salmon farming facility in Nesna, Helgeland, Nordland County, Norway.
The Norwegian salmon producer will grow its fish on land using a hybrid flow-through system, protecting the fish from sea lice, the external environment, and safeguarding them against escapes. The NGT system will be used to filter and disinfect seawater before it enters the facility.
Specifically, Norwegian Greentech will provide nine individual UV- and filtration-based systems, one for each of the nine inlets that will supply clean seawater to the fish tanks. Although the system is capable of treating large volumes of water, it has been designed to strike the right balance between power and efficiency, thus minimizing operating costs and environmental footprint.
Moreover, its UV- and filtration solution is chemical-free and highly energy efficient. This ties in perfectly with the vision of Arctic Seafarm, which, according to an earlier statement by CEO Magnus Kibsgaard, was founded with the goal of farming salmon in a more sustainable way than traditional aquaculture does today. "This applies to fish welfare and minimizing our impact on the climate and environment," he explained.
As mentioned, Norwegian Greentech will deliver its energy-efficient UV- and filter-based water treatment technology as a subcontractor to Eyvi, which, together with Totalbetong will deliver the hybrid recirculation system where seawater is pumped from the sea for filtration and disinfection before entering the facility.
Participating in Arctic Seafarm's project represents a milestone for Norwegian Greentech in land-based aquaculture. However, the technology to be applied has been used for many years on board approximately 800 vessels, where, the company explained, it disinfects seawater in compliance with much stricter requirements.
"This is our breakthrough contract within large-scale land-based fish farming, but our technology is already installed on board more than 30 wellboats. We are highly familiar with the Norwegian aquaculture industry's technological and biological requirements," stated Børge Gjelseth, SVP Commercial at Norwegian Greentech.
"We are excited to see that activity level in the Norwegian land-based aquaculture market is picking up, and we are proud to be chosen by Eyvi to support their turnkey delivery to Arctic Seafarm," he also said. Deliveries will take place in the second half of 2025 and early 2026.
When construction began in October 2024, Arctic Seafarm noted that building a land-based aquaculture facility "requires the best technology" and that is why they had partnered with Eyvi, Totalbetong, and Johs. J. Sylteren.
"We have set very high standards, both in terms of sustainability and fish health and welfare. Eyvi and Totalbetong have delivered on this and more. The groundwork is already underway, and we look forward to realizing the project," CEO Magnus Kibsgaard then said.
To achieve this, the contract now signed by Norwegian Greentech with Eyvi adds to others already announced for the project such as those signed with SIMONA Stadpipe to supply a complete piping package for the entire water distribution and fish transport at the facility, or with the Swedish-Swiss multinational electrical engineering corporation ABB, which will be responsible for automating the land-based salmon facility in Langsetvågen, a Nesna industrial zone.
In Phase 1, for which it obtained funding last October, Arctic Seafarm plans to produce approximately 10,000 tons (8,000 tons HOG) and employ about 40 people. Nevertheless, the 15,000 tons MAB (Maximum Allowable Biomass) grant will allow the production of up to 25,000 tons of salmon in subsequent phases. Once complete, it will employ around 100 people.
