Decontamination consultancy

We work with an innovative decontamination tool. This means that a simulation model of the water system is being built. With this simulation model it is possible to quickly identify the cause of the contamination “virtually”. After all, if the cause is not tackled, the Legionella concentration in the system will come back and even increase over time. Several proposals will be made to tackle the cause by implementing a renovation measure. The simulation model predicts in advance the effects of the various renovation measures. So no time is wasted testing individual measures in practice. In addition, proposals for energy savings can be made.

Step 1

Notification of Legionella problem

In the first step, we receive a notification from the customer of a Legionella problem. This report will be treated discreetly.

Step 2

Study the hydraulic scheme

Then, we will study the sanitary hot water system on the basis of the hydraulic scheme. Questions and ambiguities are listed here.

Step 3

Site visit

During the 3rd step, we go on a site visit. Hereby, the questions that remained after studying the hydraulic scheme are answered.

Step 4

Perform additional measurements

If necessary or desired, we can perform additional measurements. This can range from measurements of temperatures, flow rates to Legionella concentrations.

Step 5

Compiling a simulation model

With the help of our decontamination tool, the case-specific simulation model is built and calculated within 24 hours after obtaining the necessary data (hydraulic schedule and site visit). Our case-specific simulation model allows us to identify the causes of the contamination in existing contaminated buildings, and to choose suitable decontamination measures for the contaminated system.

A case-specific simulation model can be compiled for any building with a hot water demand, such as sports complexes, hotels, residential care centers and hospitals.

Step 6

Calculate variants in terms of renovation measures and/or controls

The entire hot water system of your building is dynamically simulated, which makes it possible to predict the temperatures and Legionella concentrations throughout the system at any time. For example, the contamination risk associated with a particular part of the installation can be assessed, temperature regimes can be optimized and the risk of contamination can be reduced. In addition, the simulation model can also be used to propose energy saving strategies.

Now that the simulation model has been drawn up, we can test the effectiveness of various renovation measures and/or controls "virtually" before implementing these measures in practice (e.g. insulating certain pipes, adjusting flow rates of certain circuits, etc.).

Step 7

Advice on the most effective measure(s)

Based on this, we provide advice on which case-specific measure(s) will ensure that the contamination disappears and does not recur. The measures we propose are sustainable and effective on the long-term. Important parameters here are health, energy use, water use and/or cost.

Step 8

Support during implementation

The customer chooses which measure is most feasible for him, we offer support during the implementation of this/these measure(s).
