 Project abstract

 

The main objective of the NAWADES project is to study, design, produce, and test new water desalination filter technology from four points of view:

  1. The structure of multi-layer membrane filter, including UV light distributed by glass fibres inside the membrane stack.
  2. The materials used to build the filter, including fouling and scaling monitoring
  3. The coating treatments applied to the surface of the filter using plasma and nano-TiO2 fibres
  4. The filtration process with integrated removal of bio-fouling.

The new filter technology shall provide long-life and antifouling filters to be used in Reverse Osmosis (RO) water desalinisation processes with a higher efficiency and life-time, less energy consumption (lower pressure), and less maintenance (lower cost).

 

 Objectives

 
  • To establish the analytical base for our innovative and integrative approach.
  • To investigate electric field based repulsion mechanisms that enable the removal of charged molecules and ions away from the membrane surface to allow higher fluxes.
  • Harvesting of clean salts that are not contaminated with chemical cleaning agents used in SoA filter.
  • Applications
  • Surface engineering by plasma treatment as Anti-Scaling technologies.
  • To develop a photo catalytic Anti-Fouling technology based on the integration of glass fiber UV-light distribution and TiO2 catalytic nano-technology inside the membrane preventing biofilm formation in the water desalination processes and distributing the light inside the membrane stacks without damaging the polymere structure of the membranes.
  • To use optimal process parameters in filtration by integration of a sensor electrode structure within the membrane system. This will enable to get a 3 dimensional monitoring of the membrane.
  • To demonstrate filters with longer life, enhanced efficiency, and self-cleaning properties to be intensively tested in Spain under industrial conditions.
  • To integrate the single technologies (anti-scaling, anti-fouling, monitoring) into one robust cost-effective sea water desalination technology.
  • To quantify economic and environmental benefits using the new RO membrane systems compared to conventional RO membrane systems.
