the potential of reusing greywater from the perspective of microbiological safety

Type of project: MSc Thesis/internship
Starting date: September/October 2023
Duration: 6 – 12 months
Location: Wetsus Research Institute, Leeuwarden, the Netherlands

There are a few possibilities for allowances:
– The allowance for students is €200. The student can apply for ‘Wetsus Grant’ allowance (€200 extra; an internal committee decides if the allowance will be granted).
– Students can apply for Erasmus; (if the Erasmus grant is less than €400, the student can apply for the Wetsus Grant).
– Erasmus
*The Wetsus Grant allowance is not guaranteed and must be approved by the Grant Committee.

Project background

This project focuses on the potential of reusing greywater. In a pilot wastewater treatment plant, greywater is treated by aerobic biological processes combined with a nanofiltration unit. Once treated, the greywater undergoes a short storage period before being directed for various reuse purposes in households. However, one critical aspect that requires investigation is the microbial quality of the treated greywater, particularly after a certain duration of storage. In this internship/thesis project, you are expected to investigate the microbiological safety of the treated greywater with an experimental setup and explore the potential of greywater reuse.

Your responsibilities

  • Sampling from the wastewater treatment plant and running the experimental setup
  • Sample analysis, including chemical analysis, culturing, microscopes, and molecular techniques, identifying potential pathogens and contaminants
  • Data analysis and reporting

Our requirements

  • Background in microbiology/environmental engineering or related fields
  • Lab experience is required.
  • Good English communication skills, both writing and speaking
  • Preferably with driving license
  • Currently enrolled in Master’s studies
