Responsibilities/Job Description

We are looking for a junior researcher to study both the fundamental and applied side of iron removal in water treatment. Currently, soluble iron(II) is converted to insoluble iron(III) during aeration forming aqueous iron flocs. This is removed upon filtration, which requires frequent backwashing and generates large sludge streams. In our idea, iron is removed anaerobically by forming the iron-phosphate mineral vivianite. It has shown to reduce the sludge volume to a third, while a valuable product is formed instead of a waste product. This novel concept has been awarded an NWO Open Mind grant, allowing to continue this research for an additional year. The title of the project is ‘From waste to value: vivianite precipitation to recover iron from anaerobic groundwater’. See article and pitch. The next steps will be to test this concept in different process conditions and to make the transition from lab scale to pilot scale. Another possible application which will be investigated is the removal of iron from anaerobic membrane concentrate streams.

It is a completely new approach of water treatment, which might become more popular in the future. You will take the lead in the experimental lab work and have the option to work both in the Waterlab of Civil Engineering and Geosciences (CiTG) as in the Environmental Biotechnology lab of Applied Sciences (TNW). We are looking for an enthusiastic researcher with preferably experience in (chemical) lab work. At the end of the project, it is likely a scientific publication will follow.

You will be working together and guided by PhD candidate Ir. Roos Goedhart (CiTG), Associate Professor Dr. Ir. Doris van Halem (CiTG) and Professor Dr. Ir. Mark van Loosdrecht (TNW).

What we offer

  • Working on a novel research theme
  • Great opportunity to position yourself in the field, collaboration with experienced researchers.
  • Independent research opportunity – research open to your ideas
  • Collaboration with Dutch drinking water companies
  • Possible co authorship for scientific publication.
