Natural organic matter in drinking water

Occurence and removal of NOM for drinking water production

Natural organic matter (NOM or DOC: Dissolved Organic Carbon) concentrations gradually increase in surface water and interfere with treatment processes. In this international course you will learn about the latest developments and innovations in NOM characterisation and removal.

Innovative NOM removal processes are currently being demonstrated in North Sea region (the Netherlands, Belgium, UK and France), in the DOC2C's research project (, like fluidized or suspended ion exchange and in-line coagulation. The insights of these projects are shared with you by those who worked on the projects.

We will also look into the treatment (and re-use) of brine from the ion exchange processes. The course will offer room for and promotes interactive discussion and will be combined with feasibility studies for full-scale application and a visit to Aquatech (both optional).

Learning goals

In this course you will learn:

  • To understand the behaviour of NOM in natural water and the inference of NOM on treatment processes
  • To understand the principles of NOM removal processes such as ion exchange and (advanced) coagulation
  • To understand the possibilities and challenges with regard to brine treatment (and re-use)
  • To be able to use the obtained knowledge in the conceptual design of a drinking water treatment system
  • To evaluate drinking water treatment systems on its feasibility with respect to NOM removal



This course is targeting scientists, engineers, decision makers concerning drinking water treatment in the North Sea region.
