Vortex®

Semi-closed system. Salmon lice thrive best in the upper layers of the ocean, and this is why there is a cover on the upper water layer that stops the lice from entering the net-pen. In order to get enough fresh seawater, Vortex® pumps fresh seawater up from the depths below the net-pen.

Function

The thrusters create a vortex that lifts the water from 25-30 meters depth. The water flows through the center of the pen all the way to the surface. The constant circular flow forces used water to sink down the side walls. At a depth of 12 meters the water hits a “terrace” and it is pushed out through the side wall.
