The joint R&D project REINER was performed by Hammann GmbH (Annweiler am Trifels, Germany) in cooperation with RWW Rheinisch Westfälische Wasserwerksgesellschaft mbH (Mülheim Ruhr, Germany) and the University of Duisburg Essen (Duisburg).
Fouling occurs in pipelines during operation. This fouling material decreases the hydraulic performance of the pipelines.
Increased friction leads to an increased pressure drop and to an increased demand of energy for the transport of water.
Effective cleaning improves the hydraulic performance and decreases the demand for energy.
This research project was running from 2015 till 2017 and had two key objectives:
The first objective was the control optimization of the COMPREX®-process. The performance of cleaning will be increased significantly by adjusting the operational parameters. Therefore, a box for mesurements and control will be developed to conduct the COMPREX®-process. With a precise control circuit.
The second objective was to improve the hydraulic performance of water pipelines with an optimized COMPREX®-process. By means of analysis indicators for the hydraulic state and to prove energy savings new tools for measurement and were used.
Based on these results, a service package will be designed. This contains the analysis of the pipeline network, calculation of potential energy savings, the optimized COMPREX®-process and documentation of energy savings.
Further, pipelines as well as pipeline networks will be able to be analyzed. Thus, the crucial parts of a complex pipeline network will be identified and cleaned.
