Direction:Dipl.-Ing. Hans-Gerd Hammann
Coordination:Prof. Dr. Ulrich Szewzyk
Participants:8 research parters (among: HAMMANN GmbH)
5 industrial partners
Type of participation:Participation as research partner
Project:Sub project 8: Effectiveness of the COMPREX®-process for removal of ochre from raw water pipelines, well pipelines and risers


From 2011 to 2014, we participated as research partner in the joint project „Microbiology of ochre formation in technical systems“ funded by the Federal Ministry of Education and Research. Key objective of the project was reenabling installations, blocked by ochre, to preserve resources – with less demand of water for cleaning and energy savings by regularly cleaned installations and pipes.

For that purpose, a test rig with transparent pipes has been installed. On these pipes, magnets with different but defined forces were installed. Further, iron elements were fed into the pipe to simulate ochre impurities with different adhesion forces.

In this research project, we succeeded to prove the effectivity of our COMPREX®-technique for the removal of ochre from raw water pipelines, well pipelines- and risers.

In the context of this project, two patents were granted.
