The research leading to these results has
received funding from the European Union’s
Seventh Framework Programme (FP7/2007-2013)
under grant agreement nº 280995
Problem
Membrane FoulingMembrane Fouling
is a technical challenge for water filtration processes
�Decrease flux
�Reduce membrane lifespan
�Increase in maintenance costs (cleaning, energy)
Fouling causes:
�Increase in maintenance costs (cleaning, energy)
�Low treatement efficiency
Project OverviewObjectives
To develop a new generation of nanostructured
Low-Fouling and Self-Cleaning
Membranes for Water Purification
possessing several key properties such as:
�catalytic degradation of pharmaceuticals and organics�catalytic degradation of pharmaceuticals and organics
�removal of heavy metals
�scavenging of precious metals and rare earths
