Flexible operation of a Wastewater Treatment Plant (Id 237)

No current offer!

As part of the Energiewende, the Institute for Fluid Dynamics at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) is adapting energy intensive processes for the production of chemicals to be supplied only with electricity from renewable resources.
Wastewater treatment plants (WWTP) are the single largest energy user of most municipalities in Germany. In recent years a number of initiatives have aimed not only at making WWTP more energy efficient, but energy self-sufficient.
The objective of the thesis is to model a WWTP in Simba#, and assess its feasibility to operate with intermittent electricity, assisted by a number of buffer technologies.
During your thesis, you are expected to perform the following tasks:

  • Collect data on wastewater treatment plants using renewable energies.
  • Model a treatment line for a WWTP capable of removing organic matter and N.
  • Adapt the process for its operation with an intermittent energy supply.
  • Assess the compatibility of the process with flexible water electrolysis and air separation.
