Cleaning and flushing of pipelines

we secure the municipal water cycle

Welcome to comprex® Municipal

Municipal networks are your core business. Ours too.

For decades, we have been successfully working for numerous municipal supply and disposal companies throughout Germany and beyond. Our goal is to clean drinking water, raw water and wastewater pressure lines efficiently and sustainably, as well as to provide competent service around the network on a regular basis. Good planning is the be-all and end-all. That’s why we get a precise picture of the area to be flushed in advance – directly on site or using Planwerk.
Together with you, we determine the individual flushing routes with feed-in and feed-out points. Then we provide a suitable team from our qualified technicians who not only make optimum use of our comprex® and extraQt® processes, but also bring with them a high degree of experience, know-how and professionalism. On time at the agreed date we are at your place, so that it can start.

Our processes for municipal pipe cleaning are versatile:

We are specialized in these cleaning applications

We operate throughout the municipal water cycle and specialize in versatile purification applications. Find out here how our processes are used successfully and efficiently from drinking water production to wastewater treatment.

Water extraction

Raw water is the source of our drinking water. From wells it reaches the waterworks with the use of pumps via raw water pipes for treatment. We restore the capacity of your raw water and well lines by efficiently removing sediment.

Applications:

Water distribution

The highest hygienic requirements apply from the waterworks to the end consumer. Our goal is to ensure that you can continue to supply consumers with hygienically safe drinking water from clean pipelines.

Applications:

Wastewater disposal

In areas with flat topography, pressure pipes transport wastewater from the pumping station to the treatment plant. We ensure that you restore and maintain the full capacity and efficiency of your wastewater pressure lines.

Applications:

Wastewater treatment

Deposit formation in the treatment of wastewater significantly affects the function and capacity of pipelines at wastewater treatment plants. Our process effectively cleans the versatile piping systems and effectively removes existing deposits.

The advantages at a glance

comprex® process

comprex® is a patented impulse rinsing process developed by us and proven in practice and works entirely without chemicals, instead on a physical basis – using only air and water. comprex® nectcare is condition-based gate valve maintenance for water distribution and an optional additional service to our municipal pipe cleaning.

Applications:

Additional service:

extraQt® process

In lighter cases of pipe network maintenance or as a maintenance measure of thoroughly cleaned networks, our water suction flushing extraQt® is the appropriate solution. In addition, we offer a condition-based network evaluation with extraQt® netcare, which allows us to give you an objective overview of the condition of your drinking water networks.

01

Individual preplanning

Every cleaning measure requires careful pre-planning. With our needs analysis, we have tailored various offerings to keep your municipal networks running efficiently and safely. We work with you to create an optimal application plan and decide together which of our processes, from comprex® to extraQt®, are best suited for you. We also offer additional services ranging from the inspection of network gate valves to the technical condition survey of the pipe network.

02

Defining the flushing and cleaning sections

We carefully define with you the sections to be cleaned and determine the optimal feed and discharge points. With the schedule worked out in this way, nothing stands in the way of an optimal execution of the rinsing and cleaning measure.

03

Execution of our cleaning service

For the cleaning offers we use our self-sufficient extraQt® or comprex® trailers. This gives us the flexibility to adapt to local conditions. Depending on the pipeline dimension of the section to be cleaned, we work with several synchronized trailers if necessary. We also offer our comprex® netcare for the effective maintenance of gate valves in drinking water distribution.

04

Rinsing / cleaning process

With comprex® , compressed air is introduced into the pipeline, which expands inside to generate impulsive blocks of water and air. These cleaning-effective packages flow through the pipeline at velocities of up to 20 m/s.

With extraQt® , our suction pump increases the flow rate, effectively removing light deposits.

05

Debris removal

With our flushing and cleaning processes, we specifically generate high shear and drag forces on the inner surfaces of the pipelines. In this way, biofilms and deposits can be mobilized and reliably discharged. Our processes have a high cost-benefit factor and work without chemicals with low water consumption.

06

Turbidity monitoring

Appendix of the turbidity monitoring we can document the condition of the pipes as well as the cleaning effect. At extraQt® we even record the turbidity online with our measurement technology and evaluate the data accordingly.

06

Recommissioning

After completion of the cleaning or flushing measure, we make the pipeline ready for regular operation again. In the case of comprex® , the first step is deaeration. Finally, all fittings are returned to their intended position.
