Wastewater treatment

With comprex® we efficiently remove deposits in pipes throughout the wastewater treatment process.

Wastewater treatment plants require properly functioning pipelines. After all, these are the connecting lifelines between the various treatment steps in the process for treating wastewater and the sludge produced in the process.

We help maintain or restore operational safety for your wastewater treatment process.

comprex® enables simple and risk-free, condition-based maintenance – and maintenance produces availability.

The problem

Every major wastewater treatment plant has hundreds of meters of piping to transport water and sludge through the various treatment stages.

All wastewater treatment processes produce large quantities of sewage sludge. Particularly in the primary sludge pipelines, but also in surplus sludge pipelines, as well as special pipe sections such as grease pipelines, thick sludge pipelines and centrate pipelines, the formation of deposits, some of which adhere very firmly, occurs again and again during operation in many places.


The consequence

Wastewater treatment creates deposits that narrow the cross-section, build up pressure, and reduce the flow rate of the pumps. If no action is taken, complete clogging of the pipe and failure of aggregates or cleaning stages are the result, which requires cleaning of the pipe sections.


The procedure

Pipes at wastewater treatment plants can usually be cleaned quickly and easily with comprex®. The necessary connections are usually already in place and impulses of air and water (service water) can be used to effectively remove deposits.

For particularly stubborn deposits or hard, crystalline consistency, adding rock salt to your pulse flush is another way to restore your plumbing.


The result

comprex® represents an effective contribution to condition-based maintenance. Early action allows a trouble-free cleaning process and enables an optimal cleaning result. Do not let it come to a complete pipe blockage with the consequence of an average and interruption of operation. Contact us in time!

We have years of experience in the municipal sector

Comprex® in wastewater treatment - this is how it works!

comprex® maintains or restores performance – without the risk of sticking as with the use of pigs.

Pipes at wastewater treatment plants can usually be cleaned quickly and easily with comprex®. Storz-C flush connections are usually already in place at the required locations or nearby. In addition to our comprex® air, only your process water is used as the working medium. The discharge is easily done into manholes, basins or tanks.

As a rule, comprex® cleaning does not require any conversions or decommissioning. The pumping times and feed rates of the various clarification processes are taken into account.

To ensure cleaning success, cleaning should be performed regularly. It has been shown that deposits not only increase over time, but also solidify and then become much more difficult to remove.
