Stabilising water quality in aquaculture

In aquaculture, water quality has a direct impact on system stability, fish condition, maintenance and operational reliability. Due to recirculation, feed load, organic matter and microbiological activity, water behaviour can change over time.

CWN assesses each installation to determine whether nano cavitation can contribute to a more stable and better controlled water system, as an addition to existing filtration, biofiltration, UV, aeration or other water treatment.

Why water quality can fluctuate

Aquaculture systems are constantly changing. Feed load, excretion, organic matter, temperature, oxygen, pH, biofiltration and microbiological activity all influence each other.

When one or more factors change, water quality can become less predictable. This may become visible through turbidity, contamination, biofilm, fluctuating measurements or a greater need for corrective measures.

For stable operations, it is therefore important not only to measure individual parameters, but also to look at the behaviour of the complete water system.

What CWN adds

CWN applies nano cavitation as an additional physical treatment within the water circuit. The application is tailored to system volume, flow rate, water load, existing filtration, biofilter, oxygen management and critical zones.

  • More control over microbiological pressure in the water system
  • More stable water quality under fluctuating load
  • Support for existing filtration, UV or water treatment
  • Less recurring contamination in basins, pipes and tanks
  • Technical assessment based on your installation and measurement data

From fluctuations to better system control

Stabilising water quality requires insight into the complete system. CWN looks at the interaction between water load, fish density, feeding regime, flow, existing treatment and critical zones.

If CWN is technically suitable, we validate this with a pilot under practical operating conditions. This makes it visible whether nano cavitation can contribute to more stable water quality, less recurring contamination and better control over system behaviour.

Frequently asked questions about water quality in aquaculture

Short answers to frequently asked questions about water quality, microbiological pressure and the use of CWN Free and Tube.

Which water quality issues can CWN help make more manageable?

CWN is assessed in cases of recurring microbiological pressure, contamination, biofilm-sensitive zones, fluctuating water quality and systems where corrective treatment is needed more frequently. The exact application depends on your installation and objectives.

Does CWN replace existing filtration or biofiltration?

No. CWN does not replace mechanical filtration, biofilter, UV or aeration. The technology is applied as an additional physical treatment within the water circuit.

Does CWN fit within my aquaculture system?

CWN can be flexibly integrated into different aquaculture systems. Together, we assess where the technology can technically contribute the most, based on system volume, flow rate, water load, fish density, existing technology and critical zones. This results in a solution that fits your installation.

Does CWN affect the biofilter?

In aquaculture, we always assess how CWN can be positioned without unnecessarily disrupting the function of the biofilter. The biofilter retains its own role within the nitrogen cycle and biological stability.

How do we demonstrate the impact of CWN?

We define together in advance which goals are important for your installation. During a pilot, we monitor these through measurements and practical observations, for example water quality, microbiological load, contamination, biofilm-sensitive zones, maintenance needs and system stability. This makes the contribution of CWN visible within your own aquaculture system.

Would you like to know whether CWN can contribute to more stable water quality in your aquaculture system? Based on system volume, flow rate, water load, existing filtration and measurement data, we assess whether a pilot is technically relevant.
