Swedish ozone generator awarded water treatment contract


Swedish ozone generator supplier Primozone has been selected to provide a complete ozone solution for the expanding facilities at SalMar Settefisk, Follafoss who is a part of SalMar ASA one of the largest producers of salmon in the world.
SalMar Settefisk in Follafoss, who produces ten million smolts (fry) a year, 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 Primozone system controller and the design and construction of the dissolution system

Primozone was specifically requested as the supplier of the ozone solution by both SalMar Settefisk and Nofitech, the designer of the RAS system, as the best available option on the market. SalMar already has a Primozone GM18 ozone generator installed since two years and Nofitech has 25 years of experience in designing land-based fish farms and knows the importance of a well-designed ozone system.

Pure water a prerequisite

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 a 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.

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.
