BACKGROUND
Xenobiotics are constantly introduced into the Baltic Sea, thus there is a need for eco-technology based treatment systems for removing them. Biofilters (slow filtration systems) are a method where untreated water i filtered through a biofilm grown matrix. It is low cost, and requires little process control. First tests of removing xenbiotics from wastewater using biofilters seems promising, however there is a need for pilot testing under realistic conditions.

AIM
The aim of this project is to explore and develop intensified biofilters for decentralised treatment of wastewater and stormwater for removing xenobiotics in particular pharmaceuticals. 

RESEARCH OUTLINE
Using laboratory set-ups, I will study removal rates, kinetics, and formation of transformation products using different biofilter materials in dependence on environmental parameters (redox, TOC etc.). In addition I wish to optimise, and test realistic conditions on pilot plants (1m3) located on Avedøre wastewater treatment plant. 

COLLABORATORS
The work is performed under the BONUS project CLEANWATER
