SalMar Settefisk, part of SalMar ASA, one of the largest producers of salmon in the world, produces 10 million smolts (fry) a year and is now expanding its facility with a new recirculating aquaculture (RAS) system.

Primozone has been chosen to supply and design the ozone water treatment solution for the new RAS plant. The ozone solution includes a Primozone GM18 ozone generator, a system controller and the design and construction of the dissolution system

SalMar has already had a Primozone GM18 ozone generator installed for two years.

Good water quality is a prerequisite for good smolt quality, and in the same way, good smolt quality is one of the main prerequisites for the safe and efficient production of farmed salmon. Research shows that the water quality improvement gained from ozone water treatment at RAS improves smolt growth and thus increases productivity, says Primozone.

The comparably low energy consumption of the Primozone GM ozone generator goes well with the SalMar environmental policy. The plant at Follafoss heats the water by heat exchange of the wastewater from the nearby pulp and paper industry and the surplus heat from the tanks is in turn used for power production.
