WP 4: Nitrogen removal by denitrification

In work package 4 we focus on optimizing nitrogen removal by denitrification in the different types of drainage filters. The major research tasks include:

  • Investigating the denitrification capacity in different filter substrates.
  • Quantifying N removal by denitrification.
  • Investigating green house gas emission from drainage filters.

The research in this work package will be conducted both as controlled laboratory experiments as well as field scale experiments and field scale monitoring on drainage well filters and different types of constructed wetlands.

The research activities in WP4 start up August 2010 and runs for 4 years. WP4 collaborates closely with WP2 (filter hydraulics and phosphorus retention), WP3 (filter technology development), and WP6 (modeling).


MSc projects: Several possibilities for MSc projects are available within this work package.

Ph.D. projects: A Ph.D. project on “Nitrogen removal and green house gas emissions” will soon be available within WP4/WP3.
