 Abstract:\nIn this project we propose to develop “gravity-driven membran
 e (GDM) ultrafiltration”. GDM filtration is an innovative technology tha
 t can be applied to the production of drinking water (SAFIR process) or to
  the on-site treatment of grey water for reuse (Blue Diversion Toilet deve
 loped in the Reinvent The Toilet Challenge). Instead of trying to remove t
 he biofilm\, the focus in GDM filtration is to engineer the biofilm struct
 ure so that biofilm accumulation has only a limited influence on the quant
 ity of produced water (i.e.\, the water flux). GDM filtration systems are 
 thus operated without energy\, without chemical addition\, etc\, and repre
 sent a relevant technology for developing and transient countries. In fact
 \, we observed that biological processes in the biofilm help to significan
 tly improve the quality of the permeate (e.g.\, in terms of organic substr
 ate removal\, virus retention\, degradation of microbial toxins\, etc). Th
 is novel concept of focusing process operation on peaceful “biofilm-memb
 rane” coexistence is the base of two new processes developed at Eawag (t
 he SAFIR process and the Blue Diversion Toilet) that were successfully tes
 ted in developing countries (e.g. Uganda). In this presentation I will pre
 sent some fundamental aspects of our research on GDM filtration as well as
  some examples of application.\nMore information on GDM filtration applied
  to drinking water production and on Blue Diversion Toilet (project leader
 : Tove Larsen):Short biography:\nNicolas Derlon hold a MS of Process Engin
 eering from the National Polytechnic Institute of Grenoble (INPG\, France\
 , 2005) and a PhD in Environmental Science (INSA\, University of Toulouse\
 , France\, 2008). Nicolas joined the Advanced Water Management Centre (Uni
 versity of Queensland\, Brisbane\, Australia) in January 2009 as Research 
 Officer working on anaerobic sewer biofilms. Since September 2009\, Nicola
 s is researcher at EAWAG in the Process Engineering Department. His resear
 ch interests include the biological treatment of wastewater (biofilm syste
 ms\, granular sludge system)\, the decentralized production of drinking wa
 ter (e.g. gravity-driven membrane filtration) and excess sludge reduction.
