Supporting open water applications in aquaculture
What CWN adds
CWN applies nano cavitation as an additional physical treatment in locations where water actively moves along or through the system. The application is tailored to water movement, system volume, load, placement and the purpose of the treatment.
- Targeted support for critical zones
- More control over local microbiological pressure
- Additional treatment at intakes, basins or circulation points
- Support for fouling- and contamination-sensitive areas
- Technical assessment per location and water movement
- Pilot setup
Frequently asked questions about open water aquaculture
Short answers to frequently asked questions about water quality, fish health, fouling on nets and the use of CWN Free and Tube.
Can CWN help make disease pressure in salmon farming more manageable?
CWN is used to make microbiological pressure in the water more manageable. In open water, we mainly look at zones where water movement, organic load and fish density come together. The goal is not to control the entire open water body, but to assess locally where additional physical treatment can contribute to a more stable living environment for the fish.
Can CWN reduce fouling on nets?
Nets in open aquaculture are continuously exposed to organic load, algae, biofilm and fouling. CWN can be assessed for locations where water actively moves along or through critical zones. The impact on fouling depends on flow, placement, load and the selected configuration. That is why we always assess this per location.
Can CWN help reduce the use of chemicals?
CWN is applied as an additional physical treatment. When water quality, microbiological pressure or fouling become more manageable, this can help reduce dependence on corrective measures. Whether this is possible in your situation is determined based on system design, measurement data and practical validation.
Where is CWN applied in fish farming or open aquaculture?
Possible applications include water intakes, pump circuits, local circulation points, basins, nets, pipes or other zones where water can be guided past the treatment in a controlled way. The right placement depends on flow, volume, load and the purpose of the application.
Is CWN suitable for treating an entire open water body?
Open water is less predictable than a closed RAS system. That is why we do not focus on full control of the entire water body, but on critical zones where treatment is technically meaningful. This makes the application more realistic, more measurable and easier to validate.
How do we demonstrate the impact of CWN?
We define together in advance which goals are important for the fish farm. During a pilot, we monitor these through measurements and practical observations, for example water quality, fouling, microbiological load, net contamination, fish condition and maintenance needs. This makes the contribution of CWN in the selected zone visible.
