Description
The technology has undergone successful testing over the past five years. The initial
batch was implemented in a large post-smolt system in Norway, which, for the past two years, has been producing Atlantic salmon fry.
The system operates with a salinity level of 0,5% and a range of 11-14 °C achieving a 98% water recycling rate.
Biofiltration is fully integrated with the SCADA system for automated control, with backwashing scheduled every four weeks.
