  4. Dr Jean-Christophe Schrotter Membrane R&D Director Development of advanced solutions to meet future water challenges

  5. Advanced solutions : The outline • Background • Water treatment cycle • Solutions to solve water scarcity issues • Where are we now ? • examples of current water treatment plants • What to expect for the future ? • examples of revolutionary processes

  6. Water treatment cycle Reuse water Reuse treatment Irrigation surface Drinking water Drinking water plant ground Wastewater treatment Common use Other Industry desalination Brackish or Sawater

  7. Water Reuse and Desalination Growth (m3/d) Ref : Global water market 2008, GWI

  8. Desalination and Waste water reuse Plants • Veolia references • More than 150 reuse plants (>3.2M m3/d) • Hundred desal plants (10M m3/d). More than 15% of the world’s desal installed capacity.

  9. Membranes : a Great Evolution ! Membrane: key enabling technology for desalination, reuse treatment process that needs to deliver higher quality product waters from lower quality feed waters.
