thesis/intership project: identifying the role of biological mnox/feox from drinking water treatment plants in affecting the removal efficiency of organic micropollutants (omps) in surface water, as an oxidant, adsorbent, or bioaugmentation?
Type of project: MSc Thesis/internship
Anticipated start: from July/August 2025
Duration: >5 months
Location: Wetsus, European center of excellence for sustainable water technology (Leeuwarden, the Netherlands)
Project description:
In the Netherlands, 60% of the drinking water is produced from groundwater. To ensure future groundwater extraction, aquifers must be actively recharged with surface water to maintain sufficient groundwater. However, this must occur without introducing organic micropollutants (OMPs) from surface water in the aquifer. Engineered abstraction sites and nature-based systems like constructed wetlands can remove OMPs effectively. The aim of this project is to develop engineered constructed wetlands (CWs) for optimal OMPs removal, utilizing biological FeOx & MnOx, a by-product from drinking water treatment plants, as substrate material. However, a better understanding, specifically its role as an oxidant, adsorbent or bioaugmentation agent, of biological FeOx and MnOx is required before its larger-scale application.
Tasks are:
- Maintain an OMPs removal experiment in a size of approximately 40 batch bottles for at least 4 weeks, and use a nitrogen gas exchanger to maintain an anaerobic condition in certain setups.
- Take samples every 3 – 5 days from batch bottles and process samples for HPLC and ICP analysis.
- Data analysis.
- Writing a report.
Your profile:
- Background in environmental science/technology/engineering, chemistry, or related fields.
- Basic experience or knowledge in batch degradation/adsorption study is required.
- Established hands-on laboratory and instrument experience would be a plus.
- Analytical skills in LC-MS and ICP will be a plus, and a huge plus in experience with transformation compounds screening.
- Fluent in English and good English writing skills
- EU citizen or non-EU citizen already enrolled in a Dutch university and living in the Netherlands.
Offers & benefits:
- Allowance: The allowance for students is €425 per month. If the student receives a Erasmus or other grant, this allowance is not applicable.
- Collaborative interaction within a dynamic, multidisciplinary and multinationals research team between Wetsus and Wageningen university.
- You would be part of a big EU project with industrial partners where you have the chance to expand your network and improve your skills
