The solution for contamination and impurities
We help with comprex®
The fact that comprex® is the optimal solution for a wide variety of contaminations and impurities in drinking water installations is confirmed time and again by our customers in practice.
Read our FAQs to find out how comprex® can help in the case of legionella, pseudomonads and turbidity problems in existing systems.
We also answer how the pulse flushing process can assist in cleaning before commissioning new drinking water systems.
Legionella
Legionella bacteria are ubiquitous in freshwater and can multiply in water-bearing systems. Elevated concentrations may occur if there are defects in drinking water installations. Then quick action is required. This is because legionella poses a serious health risk. The rod-shaped bacteria live in water and can cause the infectious disease legionellosis through droplet transmission.

- Senior centers & nursing homes
- Residential, Office & Commercial
- Hotels & Restaurants
- Swimming pools & gyms
- Public buildings
Pseudomonads
Microbiological contamination can occur in drinking water pipes. The causes are structural, operational or procedural deficiencies. Pseudomonads, especially Pseudomonas aeruginosa are rod-shaped bacteria. They can be dangerous for people with weakened immune systems. They are a dreaded hospital germ with antibiotic resistance. Therefore, quick action is required in the event of contamination.

- Hotels & Restaurants
- Swimming pools & gyms
- Public buildings
Turbidity
The cause of turbidity in drinking water installations is usually corrosion, especially in old steel pipes. This is usually noticeable by a reddish-brown discoloration of the drinking water. Corrosion products can clog filters, strainers, aerators or angle valves. In addition, the cross-section of old steel circulation pipes is decreasing. This reduces the flow rate.

What information you can have ready with your request
Good preparation
What kind of building
Background information, facts and figures about the building help us to understand the situation and provide you with targeted advice.
Number of taps
The number of taps gives us an initial estimate of the time required for comprex® cleaning of the drinking water system.
Pipeline material
The material of the drinking water system also plays an important role in the further procedure.
Place of sampling
This information helps to further isolate the cause of the problem and to initiate targeted measures.
A clean result in just a few steps
Our approach
01
Individual advice
Based on your inquiry, our hygiene experts first discuss the individual task with you and clarify the general conditions. In preparation for the site visit, we ask for building plans in preparation for the site visit.
02
On-site meeting and preliminary planning
The basis for a successful cleaning measure is sound preliminary planning. On site, we identify necessary conversion measures and discuss the implementation of the project with you.
03
Schedule and offer
Depending on your needs, we schedule cleaning on weekdays, weekends, during the day or at night. Based on the preliminary planning, our experts work out the detailed schedule and prepare an offer and for the cleaning measures.
04
Start cleaning
We come to you on schedule with our comprex® technology. We prepare your drinking water installation for cleaning and connect our technology. Based on the schedule, we clean your drinking water installation section by section – one after the other cold water, hot water as well as circulation water pipes.
05
Removal of microbial contamination
The comprex® unit generates controlled pulses with multi-filtered compressed air. Fed into the cleaning section, these pulses generate highly accelerated air and water blocks and enormous turbulence with strong shear and drag forces. These mobilize biofilms and deposits and reliably remove them.
With comprex® , we nevertheless clean gently and always remain below the permissible system pressure.
06
Bleeding the system
As soon as no more turbidity is visible at the sampling points, we deaerate the cleaned strand. The cleaning of this section is completed.
07
Optional: disinfection
At the customer’s request, we can also carry out chemical disinfection in accordance with DVGW W 557 after thorough cleaning of the pipeline. We use hydrogen peroxide or chlorine dioxide for this purpose.
08
Commissioning
After completion of the cleaning and, if necessary, disinfection measures, sampling must be carried out. Care must be taken to ensure that the water does not stagnate in the pipeline. As soon as the result of the sampling is available and faultless, the drinking water installation can be put back into operation.
