Insights into the world of bioprocess engineering

The BPT and TB chairs presented a model of a wastewater treatment plant at the TU Dortmund Open Day

The model, which simulates the processes in the activated sludge and secondary clarifier, i.e. the biological stage of wastewater treatment, met with great interest.

Ronja Weidemann used the biological stage of wastewater treatment to explain the background to her PhosFad research project. This biotechnological approach to phosphate recovery uses a filamentous sulphur bacterium that extracts phosphate from municipal wastewater, for example, and makes it available again for the circular economy after treatment. Visitors were also able to observe the gliding movements of the bacterium, which is unusual in its size, through a microscope.

The laboratory tours, conducted by Jörg Fischer and Jan Graw, through the genetic engineering S2 facility, where the research work on some of the laboratory equipment was explained on the basis of projects carried out at the Chair of Technical Biochemistry, also met with great interest.
