LbLBRANE will apply the layer-by-layer technology (LbL), for the development of a novel generation of low-cost, stable and chemical resistant polyelectrolyte membranes. These PEM membranes shall show superior performance, an extended lifespan and a competitive price compared to commercially available ones.

The ultimate goal would be the production of a high performance, regenerable membranes to be cleaned in-situ, and hybrid membranes with extremely high flux or high permselectivity and mechanical robustness.

LbLBRANE thus looks into the full range of relevant aspects: exploring the technology of membrane modification, through to structural module design and finally pilot plant testing by end-users, also having regard to life cycle assessment and nanosafety issues.



  • Regenerable membranes with enhanced performance for water treatment
  • Consolidate and strengthen the European membrane market
  • Knowledge transfer between world-class experts on LbL and experienced membrane manufacturers and SMEs
