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

How to apply:

Please upload your CV (max 2 A4 pages), motivation letter (max. 1 A4 page), and a list of the attended courses and the equivalent ECTS via the application form provided below (in English). Feel free to contact Han Liu (han.liu@wetsus.nl) if you have further questions or need more information.

Towards an economy of value preservation | By Niels Faber

Abstract

The realisation of a circular economy has thus far unfolded under the assumption that it would fit within existing economic arrangements. In practice, we witness many circular initiatives struggling to give shape to their ambitions, let alone develop to maturity. These past months, various material recycling organisations terminated their activities, seeing virgin alternatives from other parts of the world flooding the market at prices against they cannot compete. If the transition towards a circular economy (i.e. an economy of value preservation) is to be taken seriously, a new perspective on value in our economic system seems unavoidable, as the rewriting of the rules of the economic game. At this moment, current perceptions of value stand in the way of this transition both at micro as well as macro levels. Several contours for a collective exploration of new directions of value and economic configuration that foster circular transition will be addressed.

Searching Innovation for the Common Good | By Cees Buisman

Abstract

In his key note he will conclude after a life of innovations that it is impossible that humanity will stay within the save planetary boundaries with innovation only. We should be more critical about the behaviour of the rich population in the world and more critical about new innovations that prove to be dangerous, like the PFAS crisis shows at this moment. In his keynote he will investigate how to look at the world that can stay within the save planetary boundaries, how should we change ourselves? It is clear if we only talk about the words of science and systems we miss the essential words of how we should cooperate and change ourselves. And his search for coherent save innovations. Which innovations will be save and will lead to a fair and sustainable world? And will lead to a world we want to live in.

Future-fit economic models: What do they have in common – how can they join forces? | By Christian Felber

Abstract

There is a growing number of new sustainable, inclusive, cohesive, participatory, just and humane economic models. A possible next step in the discourse about them is the comparative analysis in order to find out key commonalities, potential synergies, and “requirements” for a future-fit economic model. The author and initiator of the Economy for the Common Good provides an overview of these „new sustainable economic models“ and compares them according to underlying values, principles, and practical ways of implementation. The keynote addresses the cooperative spirit of the conference and prepares the ground for its public highlight on the eve of June 3rd, the round table with representatives of diverse future-fit economic models.

The era of postgrowth economics | By Matthias Olthaar

Abstract

The scientific debate on whether economies should always continue to grow increasingly becomes a political and societal debate. On the one hand further growth for the most affluent countries seems neither possible nor valuable, but on the other hand there is still lack of understanding and knowledge what a non-growing economy should look like and could best be governed. In this lecture we discuss various policy measures that can be realistically implemented, take into account government finances and aim at a higher quality of life despite a non-growing economy.

Democratic principles for a sustainable economy | By Lisa Herzog

Abstract

Democracy is under pressure, and less and less able to stir the economy into a sustainable direction. Therefore, to stabilize democracy and to make possible the socio-ecological transformation of the economy, democratic principles need to be implemented directly in the economy. This is not only a matter of morality, but also has practical advantages. Democratizing the economy can increase legitimacy and take advantage of the “knowledge of the many” to accelerate the transformation. Democratic practices, especially deliberation, allow bringing together different forms of knowledge, which is crucial for the local implementation of principles of social and ecological sustainability. This talk explores what this idea means in more concrete terms, from democratic participation in the workplace to the democratization of time.

Market, state, association, and well-being. An historical approach | By Bas van Bavel

Abstract

Over the past decades, markets have conventionally been seen as the best instrument to stimulate economic growth and enhance prosperity and well-being. The automatic link between markets and economic growth is increasingly questioned, however, as well as the automatic link between economic growth and enhancement of well-being. This has led to attempts to capture well-being development more directly than through GDP per capita figures and has produced a more variegated picture of well-being growth. Also, this has led to a shift of focus to other coordination systems than the market, as primarily the state but increasingly also the association. Analyses of the historical record suggest that especially the latter could be a vital component in future well-being.
