Reducing biofilm in basins and irrigation lines.

Reducing biofilm in basins and irrigation lines.

Biofilm in basins, pipes and drip systems can lead to recurring contamination, fluctuating water quality and clogged drippers.

CWN assesses each installation to determine whether nano cavitation can contribute to a more controllable recirculating water circuit, as an addition to existing filtration, UV or oxidative treatment.

Why biofilm keeps returning

Many greenhouse companies clean pipes, flush systems or use oxidative agents such as H₂O₂. Yet biofilm can return over time.

This is often caused by a combination of organic load, stagnant zones, pipe material, temperature, flow and microbiological pressure in the recirculating system.

When conditions remain favourable, microbiological build-up can form again on wet surfaces within the water circuit.

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, flow patterns, existing water treatment and critical zones.

  • Less recurring microbiological build-up
  • More control over contamination in basins and pipes
  • More stable water quality in the recirculating system
  • Support for existing filtration, UV or oxidative treatment
  • Better controlled reuse of irrigation and drain water

From recurring contamination to a targeted approach

Biofilm and microbiological pressure require more than simply cleaning or dosing again. CWN looks at the complete water circuit and determines where additional physical treatment can technically contribute the most.

If CWN is suitable, we validate this with a pilot under practical operating conditions. This way, you do not rely on assumptions, but on measurable practical experience within your own system.

Frequently asked questions about biofilm in basins and pipes.

Short answers to frequently asked questions about biofilm, drippers and the use of CWN Free and Tube.

Does CWN remove biofilm from irrigation lines?

CWN is used to make microbiological pressure and system instability easier to control. The impact on biofilm depends on system design, hydraulics, water load, positioning and measurement strategy. That is why we assess this per installation.

Does CWN replace cleaning, flushing or H₂O₂?

No. CWN is applied as an additional system technology. Cleaning, flushing, filtration, UV or oxidative treatment can each retain their own function within the water system.

When is CWN relevant for biofilm problems?

CWN is particularly relevant when biofilm returns after cleaning, drippers become contaminated, microbial counts fluctuate or corrective treatment is needed more frequently.

Where is CWN installed in biofilm-sensitive systems?

That depends on the installation. Possible locations include basins, silos, pipes or zones where stagnation, organic load and recirculation come together.

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, corrective treatment and system stability. This makes the contribution of CWN visible within your own water system.

Would you like to know whether CWN is suitable for your biofilm-sensitive water circuit? Based on system volume, flow rate, current water treatment and measurement data, we assess whether a pilot is technically relevant.
