Fish farming in recirculating systems is expanding in the aquaculture industry. In Recirculating Aquaculture Systems (RAS), effluent water is treated to restore its quality and allow the reuse of more than 90% of intake water.
A key point is particle removal. Hydrotech filters have particle removal efficiencies of over 90%.
Our team of biologists and engineers work together with your design teams to ensure particles are not dissolved or destroyed before they reach the screen – and to make sure the system brings maximum efficiency.
The steps usually required in a modern RAS are:
- Solids removal
- Ammonia and organic matter removal
- Carbon dioxide degassing
Our microscreens remove major loads from the biofilter and act as an absolute filtration step, removing parasites from the recirculation loop. This feature has become a crucial success factor in some installations such as eel farms.
The benefits of Hydrotech filters:
- ALPHAFLEX™ patented screens with high efficiency
- Small footprint
- Low impact and load on the natural environment
- Reduced energy costs
- Easy maintenance and monitoring of performance
- 30 years of experience in the aquaculture industry
