Internship Energy neutral wastewater treatment plants – Saur EUROPE – Doetinchem



In the future, municipal wastewater treatment plants should become energy and carbon neutral. To meet this requirement, a process is required in which most of the organic pollution is converted into energy, instead of being oxidized and lost to the air. This

can be achieved by using a digestor producing energy, instead of an aerobic bioreactor oxidizing COD. This digester should be operated with a concentrated feed and therefore, the wastewater treatment plant of the future will start with the concentration or harvesting of COD for the digester. Two promising processes have been identified for this concentration step.

Your goal

The goal of this project is to compare a high loaded bioreactor to a fine sieve and find the best solution for concentrating COD. Parameters to take into account for this comparison are the removal efficiency, costs, floc stability, biogas production and carbon footprint.

What will you be doing? We have listed it for you:

  • Performing laboratory experiments.
  • Making a comparison based on your experimental results, previous pilot results and theoretical calculations.
  • Giving an advice based on your final evaluation.

Internship available from November 2024 onwards.
