The Salsnes Filter SFK Series is a rotating belt filter designed for installation in concrete channels or custom-made steel- or plastic tanks.
The SFK Series is specifically designed for filtration of water from fish tanks in RAS and flow-through land-based aquaculture plants, or other industrial application with low particle load.
As the SFK Series is design for installations within channels or tanks, the filters do not have integrated overflow protection. This must be included in the channel-/tank design upstream of the filters. Likewise, the filters in the SFK Series are not supplied with integrated sludge handling.
The SFK Series consists of three different models, SFK200, SFK400 and SFK600, with different treatment capacities. For removal of sludge from the filter belt, the filters can be equipped with air-knife or water-knife (specifically for aquaculture installations). For maintenance cleaning, the filters can be equipped with either low-pressure hot- or cold-water wash, or high-pressure cold-water wash.
