Description

The project focuses on biological filters for drinking water treatment headed by the Technical University of Denmark (DTU). Sand filters for iron- and manganese removal are commonly used in Denmark for drinking water treatment subsequent to aeration, as this is also carried out by BWB in Berlin.

The aim of the project is to improve the performance of these filters by identifying the optimal microbial population and defining a framework for best removal of additionally ammonium, methane and trace organics.

KWB will contribute to this project in three work packages:

  • Presence of the right organisms: a comparative study will be carried out integrating existing results from Berlin and those acquired in the course of the project in DK,
  •  Process understanding: mutual experiments on trace organics’ removal will be conducted in Berlin and in Denmark,
  • Process optimization: Knowledge exchange between researchers from DK and practitioners from BWB to identify practicable possibilities for optimization. If applicable, trials for process optimization will be carried out in Berlin.

The project was approved for funding by the Danish Council for Strategic Research (DSF) in December 2009. KWB will participate with in-kind contributions.
