Marine Harvest Dalsfjord
How AnoxKaldnes increased production for Dalsfiord despite capacity challenges
Marine Harvest Dalsfjord Marine Harvests location at Dalsfjord near Volda-Norway, produces salmon smolt. Between 2009 and 2012 Krüger Kaldnes AS planned and delivered two plants to Dalsfjord for the production of more than 4 million salmon smolts per year. Each product line has its own separate water treatment system (RAS1 and RAS2).
They required the design and build of two separate low footprint RAS-plants, both outdoor and indoor.
Facing the challenge of very limited available area, RAS1 was designed as an extremely compact plant. Less than 200 m² is used to treat 2,850 m ³ water. Kaldnes® RAS is located in a separate building, while the fish tanks are placed outside. RAS 2 is an operator-friendly indoor water treatment plant with good access to the equipment in acompact design. Both plants are highly automated.
RAS 1 has a capacity of 3,000 kg per day feeding, with a total hydraulic capacity of 4,275 m³ /hour. It is an extremely compact plant with a foot print of less than 200 m² including deepshaft oxygen cones. RAS 2 has a capacity of 2,000 kg per day feeding, with a total hydraulic capacity of 2,400 m ³ /hour and a foot print of less than 250 m² .
