ULTRA-FILTRATION AND MICROFILTRATION PILOT-PLANT INVESTIGATIONS TO TREAT RESERVOIR WATER

Currently the IWW-Rheinisch-Westfaelisches Institut fuer Wasserforschu ng gemeinnuetzige GmbH, an Institute at the University of Duisburg, th e Institute of Hygiene of the University of Bonn and the Wasserwerk de s Kreises Aachen (WdKA) are realising a project supported by the Germa n Federal Ministry for Education, Science, Research and Technology (BM BF). This project is to investigate whether membrane filtration (micro - or ultrafiltration) is able to enhance the particle removal efficien cy of an existing drinking water treatment plant. The first step of th e total investigation programme was to operate three different pilot p lants in parallel with a capacity of about 10 m(3)/h each. This paper presents results concerning the pilot plant investigations.
