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

Project description:

Biological oxygen-dosed activated carbon (BODAC) filters were operated as one of the treatments to further remove nutrients and micro-pollutants from the municipal wastewater treatment plant (WWTP) effluent in Emmen, the Netherlands, to produce ultrapure water.

In parallel, a BODAC pilot-scale filter was tested for its performance in removing micro-pollutants, mostly pharmaceutical, from WWTP secondary effluent. The tests also include varying empty bed contact time (EBCT) to allow higher loading while maintaining relatively high removal efficiency. In the BODAC filter, adsorption, bio-degradation, and later bio-regeneration were thought to be the main processes involved in the micro-pollutant 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).
