Improving microbiological control of irrigation and drain water

In recirculating irrigation and drain water systems, water is reused again and again. This is efficient and increasingly necessary, but it also makes microbiological stability more important.

CWN assesses per installation whether nano cavitation can contribute to better control of recirculating water, as an addition to existing filtration, UV or oxidative treatment.

Why recirculating water requires attention

In recirculating water systems, water, nutrients, organic matter and microorganisms remain present in the system for longer periods of time.

As a result, microbiological build-up can occur in basins, pipes, filters, silos and other wet parts of the installation.

When the water load increases or conditions become favourable for microbial growth, water quality can become less predictable. This is often reflected in fluctuating analyses, recurring contamination or an increased need for corrective treatment.

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 water treatment and critical zones.

More control over recirculating irrigation water
Additional treatment of drain water flows
Support during fluctuating microbiological load
Reduced dependence on corrective peak treatments
Technical assessment within existing installations

From water reuse to more stable system control

Reusing water requires more than disinfection at a single point in the system. CWN looks at the complete water circuit and determines where additional physical treatment can contribute most effectively.

If CWN is technically suitable, we validate this with a pilot under practical operating conditions. This allows you to see in your own installation whether nano cavitation contributes to more stable water quality and better control of the recirculating water circuit.

Frequently asked questions about irrigation and drain water

Short answers to common questions about recirculation, water quality and the use of CWN.

Does CWN replace existing water treatment such as UV, filtration or H₂O₂?

No. CWN is applied as an additional system technology. Existing technologies continue to serve their own function. The added value lies in the additional physical treatment within the water circuit.

Is CWN suitable for every irrigation water system?

Not automatically. Suitability depends on system volume, flow rate, water load, existing technology and the locations where microbiological build-up occurs.

Can CWN support the reuse of drain water?

CWN can be relevant when drain water is reused and microbiological load or system contamination becomes difficult to predict. We assess this per installation.

Where is CWN installed?

This depends on the installation. Possible locations include basins, silos, pipes or other zones where recirculating water and microbiological load come together.

How do we demonstrate the impact of CWN?

We define together which goals are important for your installation before starting. During a pilot, these are monitored 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.
