scale investigation of micro-pollutant removal using biological oxygen-dosed activated carbon (bodac) filters

Type of Project: Internship
Duration: >4 months, starting November 2023
Location: Wetsus – European center of excellence for sustainable water technology (Leeuwarden, 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).

*The Wetsus Grant allowance is not guaranteed and must be approved by the Grant Committee.

Project description:

A pilot scale Biological Oxygen-Dosed Activated Carbon (BODAC) filter is being tested for its performance in removing micropollutants, primarily pharmaceuticals, from secondary wastewater treatment plant (WWTP) effluent. The tests include varying the empty bed contact time (EBCT) to allow for higher loading while maintaining relatively high removal efficiencies and varying the oxygen concentration in the BODAC filters. In the BODAC filter, adsorption, biodegradation and later bio-regeneration were thought to be the main processes involved in the micropollutant removal mechanisms.



You will work in a highly-skilled environment for water research and contact with different topics and people. A compensation of €200 – €400 per month for living expenses will be provided, depending on your situation. You will also have opportunity to learn about other emerging micro-pollutants related topic, other than pharmaceuticals, in your project, such as Per- and polyfluoroalkyl substances (PFAS).
