At Primozone, we are proud to deliver advanced ozone technology to support sustainable aquaculture across Europe. One of our valued customers is Skagen Salmon, a land-based salmon farm located in Skagen, Denmark. They provide high-quality salmon to nearby markets with full respect for the salmon, the consumer, and the environment.

 A stable operation is essential to ensure an optimal environment for the fish. Reliable water quality and effective disinfection are key to maintaining fish health and production efficiency. To help achieve this, Primozone supplies ozone technology that supports a clean and balanced water system at Skagen Salmon.

 Our modular and adjustable ozone generators are designed to easily adapt to process requirements, ensuring optimum operation and flexibility. With a scalable design, our system can be adjusted to meet the exact capacity needed — maintaining consistent water quality while reducing environmental impact.

 By integrating ozone into the water treatment process, Skagen Salmon benefits from improved hygiene and a chemical-free disinfection method that supports both fish welfare and sustainability goals.

We at Primozone are proud to be part of this process and to contribute with our reliable ozone generator technology to ensure a stable, efficient, and environmentally responsible operation at Skagen Salmon.

The Swiss fish farm Valperca faced challenges with water quality in their recirculation system, which prevented them from producing fish at full capacity. By implementing the Primozone Ozone Water Treatment Solution, water quality improved within just a few days, allowing the farm to maximize production.

Located in the scenic Valais Valley, Valperca produces perch, a delicacy in Switzerland. The high market demand for perch, combined with limited wild supply, makes this fish highly valuable. Valperca has the capacity to produce up to 300 tons of perch per year.

“…the redox value increased instantly and after only a couple of days we had reached the desired water quality.”

In May 2010, Valperca contacted Primozone due to issues with the ozone system they had installed just months earlier. The previous system lacked sufficient capacity to maintain water quality for the designed fish volume. Water was not properly treated, redox values were too low, and the organic load in the tanks was too high, resulting in slower fish growth and limited production.

EASY-TO-USE OZONE WATER TREATMENT SOLUTION AT SALMAR SMOLT HATCHERY

SalMar Settefisk in Follafoss, part of SalMar ASA, is one of the largest salmon producers in the world, with a production of 10 million smolts (fry) per year. When expanding its facility with a new RAS (recirculating aquaculture system), Primozone® was chosen to supply and design the complete ozone water treatment solution for the hatchery.

Preferred Supplier for Sustainable Aquaculture

The Primozone ozone system was specifically requested by both SalMar Settefisk and Nofitech, the designer of the RAS system, as they considered it the best available solution on the market.
SalMar already had a Primozone ozone installation at another hatchery and was aware of its advantages, while Nofitech, with 25 years of experience in designing land-based fish farms, understands the importance of a well-designed ozone water treatment solution.
