LEMA, the four ultrafiltration research missions
  • Evaluation of membrane technologies
    LEMA evaluates different technologies on the demand of Aquasource clients and the Suez Environment group. 
  • Membrane ageing
    LEMA develops predictive and evaluative tests and tools for ageing membranes. 
  • New solutions
    LEMA is on the leading edge of ultrafiltration developments for the future. 
  • Membrane characterisation
    Working alongside private and public laboratories, LEMA participates in methodological and normative projects in ultrafiltration. 

LEMA is the reference in organic membranes, as part of the SUEZ Group.

The LEMA laboratory,

The aquasource® membrane research laboratory (LEMA) is dedicated to making progress in the field of membrane technologies.

aquasource®, pioneer and specialist in ultrafiltration, carries out innovative development of membrane filtration in its research laboratory.

Since its creation in 1984, the LEMA laboratory has placed itself on the cutting edge of industrial and environmental solutions to water treatment problems.
Our laboratory brings together many experts from various fields including chemistry, process engineering, hydraulics and mechanics. We regularly update our analysis equipment, test beds and pilot units.

Via the LEMA, aquasource® interacts with:

  • the scientific network of the SUEZ ENVIRONNEMENT Group: Cirsee, Ondeo Systems
  • private laboratories or organisations, and specialised academics: the French Membrane Club, the laboratory of chemical engineering (CNRS), University Paul Sabatier in Toulouse, University Paul Cezanne of Aix-Marseille (UPCAM), National Institute of Applied Research (INSA)…

LEMA is active in diverse research on ultrafiltration. Its work has been done in cooperation with various scientific and industrial partners

  • scientific group projects co-financed by public (French National Research Agency) and private organisations
  • Cluster organisations (Water Sensor Membrane) and competitiveness hubs (Pôle Eau)
  • Exchange platforms (Normalisation and management of innovation)
