Both salmonids and other species have proved to meet the highest quality when farmed in Kaldnes™ RAS systems.At first glance, increased growth rate (SGR) and high survival rate are obvious benefits. Furthermore, reduced stress and increased fish welfare are other advantages that Kaldnes™ RAS provides.
Kaldnes™ RAS meets the demand for flexible and reliable water chemistry. Sudden changes that may provoke potential harmful environmental factors, such as sludge accumulation are eliminated.
A central idea behind the Kaldnes™ RAS is low energy input. Therefore, head loss in Kaldnes™ RAS is kept to a minimum. Typical energy consumption rarely exceeds 2 kw/kg fish produced.
A costly input factor in intensive fish farming is pure oxygen. Kaldnes™ RAS therefore utilizes all available oxygen. Kaldnes™ RAS offer special low head oxygenating cones that ensures a full saturation with minimal pressure. Furthermore, excess available oxygen not consumed by the fish culture is utilized by the AnoxKaldnes™ Moving Bed biofilm reactor.
With proven fundamentals for more than 20 years, Kaldnes™ RAS takes fish farming to a new level!
