Cermaq selects BIO-UV group triogen ozone generator for new salmon farm

BIO-UV group has taken a major step forward in Chile’s aquaculture market, supplying its triogen ozone generator to global salmon producer Cermaq. Launched in 2022, the triogen product represents a part of BIO-UV group’s development strategy focused on the aquaculture industry, in which South America is a major market.

The ozone technology used in the triogen Positive Pressure Ozone (PPO) reportedly disinfects, increases water quality and improves process efficiency. With a reduced environmental footprint, ozone can oxidise organic and inorganic contaminants, thereby eliminating the development of waterborne diseases — a requirement in healthy aquaculture.

BIO-UV group also signed a contract with COVEPA, the southern Chile-based provider of solutions and products for the aquaculture, agricultural, and livestock industries. Due to this partnership, BIO-UV group supplied Cermaq a triogen PPO, capable of producing up to 240g/hr of ozone.

A fully owned subsidiary of the Mitsubishi Corporation, Cermaq is headquartered in Oslo and has major fish farming operations and regional offices in Canada, Chile, and Norway. Cermaq Chile is managed from Puerto Montt. It has fish farms, farming centres, and processing plants to produce Atlantic salmon, Coho salmon, and Steelhead trout. The triogen PPO generator will equip a new salmon farm being developed.

Gregorio Jofré, development and project engineer at COVEPA, said, “We have completed our first project with Cermaq. The PPO was installed at the RAS Rio Pescado aquaculture farm, which can produce fry, pre-smolt and smolt with an annual production of 250 tonnes.”

Samuel Gaez, manager of the Rio Pescado fish farm added, “The equipment is user-friendly and, in our process, it plays a crucial role in the disinfection stage, and the performance evaluation over the coming months will be decisive.”

Ozone is a simple chemical-free treatment that breaks down the particles in water recirculation systems used in aquaculture and fish farming, according to deputy general manager of BIO-UV group, Simon Marshall. “The process disinfects and oxidises pollutants present in the water, eliminates organic and inorganic contaminants, and increases the concentration of dissolved oxygen in the water,” he said, “The result is water quality for fish growth and production quality.”

BIO-UV Group has reportedly invested €1m in R&D over the past two years, with a contribution from its ozone engineering team in the UK. Since its launch, the triogen PPO range has been expanded to provide capacities of up to 1.2kg/hr of ozone. The triogen PPO generator offers local and remote control and automation benefits, modular design, a circular ozone module refurbishment and exchange service, fully interchangeable ozone modules and spares, independently controlled ozone circuits, and built-in redundancy and duty standby.
