2nd IWA National Young Water Professionals Conference

“Membrane technologies for Wastewater Treatment and Reuse”
Sony Centre Berlin, 4-5 June 2007

lecturesThe conference was attended by approximately 150 participants, with the vast majority of attendees (2/3) being young professionals from Germany, accompanied by young professionals from all over the world and some well-respected international experts in their field.

The technical program of the conference consisted mainly of contributions from German and international young water professionals including students, recent graduates and other professionals under the age of 35.  Over 40 papers and 30 posters were presented during the two days of conference and the workshop.

Content of the technical paper

The keynotes introduced the young water professionals programme of IWA, and Pierre Cote presented an interesting overview of possible future developments in membrane technology.  A current state of the art of membrane technologies for wastewater and reuse applications was also given, but it can be concluded that reuse technology with membranes is still in its infancy in Europe. 

The session of MBR process optimisation and wastewater reuse focused mainly on agricultural reuse in Italy, with regards to removal of persistant organic pollutants.  Nutrient removal and the impact of different recirculation schemes on nutrient removal was also presented. 

Some interesting novel approaches to assess membrane fouling were shown, such as the use of fluorescence spectroscopy for performance monitoring, composition of fouling layers, a metaproteomic approach for biomass characterisation, the use of flux enhancing polymers, etc.  New membrane concepts introduced were for example the use of membranes in lagoons for wastewater reuse in agriculture, also in less developed countries, and new technologies developed by several companies were also shown.

Modelling of membrane processes was shown to be an adequate tool to assist long-term experiments, and could possibly provide a first assessment of the best operating conditions.  Several lectures focused on the use of CFD to assess shear stress at the membrane surface and hydrodynamics.

The final session focused on possible career paths for young water professionals, through lectures by people from German companies such as A3 and Puron, and a project engineer from Erftverband.

3 Papers (mentioned below) and 4 posters were presented by MBR-Train fellows:
