1.Fish Tanks
Inlets and outlets are designed to ensure fast removal of feces and uneaten feed pellets and provide optimal conditions for the fish. Fish tank sizes can vary from a few cubic meters to several thousand cubic meters of water. The most commonly used materials are fiberglass, concrete and PE.
2.Mechanical Filtration
Particles such as feces and uneaten feed pellets are removed from the water using drum filters with a typical mesh size of 40-90 μm, depending on fish size and species. This process is vital for fish welfare and the stability of other water purification processes.
3.Water Reservoir 1
After passing through the mechanical filtration process, water is accumulated in Reservoir 1 and is then directed to the biofiltration system.
5.Biological Filtration
BA fixed bed biofilters break down soluble organics and ammonia to their lowest possible level, thus providing excellent water quality for the fish. The bioreactor is the heart of our RAS solution, as it maintains microbial stability in the system and captures fine solids, making the Billund Aquaculture RAS best-in-class when it comes to water clarity.
