Active research partner

As plant construction engineers, we are active in various research projects focusing on membrane development. As plant construction engineers, we consider the application side of research topics, develop plant concepts and implement them in research projects.

In collaboration with numerous partners from industry (VITO, Nickelhütte Aue) and research (Fraunhofer IKTS, TU Freiberg, TU Berlin, RWTH Aachen, Rauschert), we have already implemented various plants. In doing so, a wide range of different processes were utilized.
