Over the past six years, Mr Michael Rutz has been involved in conventional and experimental investigations into increasing the efficiency of surface filters. He was supervised by Prof Dr Goldmann from Clausthal University of Technology and Prof Dr Folker Flüggen from Nordhausen University of Applied Sciences. In his work, Mr Rutz dealt with the classification and differentiation of circulating dust particles, the creation of a "digital twin" and possible product configurators for dust filters.

The Recycling Technology Research Group Nordhausen University of Applied Sciences and Clausthal University of Technology would like to thank Mr Michael Rutz for his outstanding work as a research assistant and doctoral student and wish him all the best for his professional career outside the university.
