Ultra- and Nanofiltration in Water Treatment

Workshop on "Operational experience and research results"

Aachen, December 14th-15th, 2006

Water supply in Europe faces opportunities as well as challenges promoting the application of advanced treatment technologies such as membrane filtration. This technology can improve drinking water quality and tackle pollutants of concern such as disinfection by-product precursors or trace organics. Although membrane filtration is now applied in an increasing number of installations there is still room for improvement with respect to operational issues. Furthermore, baseline recommendations for a good operational practice have to be developed.


On December 14th, 2006 about 67 participants from 14 countries gathered in Aachen (Germany) for the Workshop “Ultra- and Nanofiltration in Water Treatrment - Operational experience and research results”. This workshop in the frame of TECHNEAU Work Area 5 "Operation and Maintenance" envisaged to present opera-
tional experiences and recent results from application oriented research on ultra- and nanofiltration for drinking water production in Europe. This workshop provided a platform for an open exchange of information on current issues between operators, research institutes, consultants, membrane suppliers and project contractors.

A range of European speakers covered the following topics:

  • Operational experiences in different European regions
  • Integration of membrane filtration in water treatment systems
  • Trace contaminants removal
  • Nanofiltration of anaerobic groundwater and natural organic matter rich surface water
  • Future perspectives of membrane technology in  drinking water production

In the context of this workshop a technical visit to the full-scale ultrafiltration drinking water treatment plant in Roetgen was organised on December 15th, 2006.

The event was hosted by the Department of Chemical Engineering (IVT) of RWTH Aachen University, member of the TECHNEAU Consortium.


All presentations are available for  download.
