Harmonization of characterization methodologies for porous membranes

Objective



MEMBRANE TECHNOLOGIE LIKE CROSS-FLOW MICROFILTRATION, ULTRAFILTRATION AND NANOFILTRATION HAVE EMERGED AS POWERFUL MILD SEPARATION TECHNIQUES. THEY HAVE THE COMMON POINTS OF BEING PRESSURE DRIVEN UNIT OPERATIONS AND OF USING POROUS MEMBRANES WITH DIFFERENT PORE SIZES. AS MORE COMPLICATED SYSTEMS ARE DEVELOPPED, THE UNDERSTANDING OF PERFORMANCE PROPERTIES OF THE MEMBRAN IN CLOSE RELATION TO THE CHARACTERISTICS OF THE MEMBRANE STRUCTURE IS NEEDED. THIS REQUIRES THE DEVELOPMENT OF CHARACTERISATION METHODS. SEVERAL TECHNIQUES HAVE BEEN STUDIED BUT THERE ARE NO STANDARD DIMENSIONS AND NO STANDARD WAYS OF MEASURING THEM. THIS LACK OF A COMMON LANGUAGE BETWEEN ALL PEOPLE WORKING WITH MEMBRANES I.E. RESEARCHERS, MANUFACTURERS AND END-USERS RESULTS IN A WASTE OF TIME AND MONEY: MANUFACTURERS HAVE TO MAKE A HIGH NUMBER OF CHARACTERISATION TESTS, THEY CAN'TCONTROL THE PRODUCTION PROCESSES OR PROVE THE ANNOUNCED SPECIFICATIONS. END-USERS CAN'T COMPARE THE CHARACTERISTICS OF COMMERCIALLY AVAILABLE PRODUCTS. ON THIS LEVEL, IT IS IMPORTANT TO NOTE THAT THE MEASURMENT METHODS WILL NOT REPRODUCE ANY REAL MEMBRANE SEPARATION BECAUSE THE AIM IS NOT TO CHOOSE THE MAMBRANE BETTER SUITED TO A GIVEN APPLICATION ONLY ON CATALOGUE. RESEARCHERS, MANUFACTURERS AND END-USERS HAVE WELL UNDERSTOOD THE NECESSITY OF AN HARMONIZATION OF THE CHARACTERISATION METHODOLOGIES. LOT OF THEM HAVE ALREADY EXPRESSED THEIR INTEREST. BUT EACH OF THEM HAS SPECIFIC REQUESTS ON SPECIFIC TECHNOLOGIES, AND ALSO SPECIFIC EXPERTISES WHICH DO NOT CONCERN THE WHOLE FIELD OF CROSS-FLOW MICROFILTRATION, ULTRAFILTRATION AND NANOFILTRATION. SO, BEFORE STARTING THE HARMONIZATION PHASE, THESE NEEDS HAVE TO BE WELL ANALYSED SO THAT EACH POTENTIALPARTNER CAN FIND HIS PLACE IN ONE OR MORE WORKGROUPS STUDYING ONE PART OF THE SCIENTIFIC PROGRAMME. THE AIM OF THIS PHASE IS TO PRECISELY DEFINE THE SCIENTIFIC PROGRAMME, TO DEVIDE IT IN SOME TASTS (FROM 3 TO 5). EACH TASK WILL BE IN CHARGE OF ONE WORKGROUP. A SCIENTIFIC AND AN ORGANIZATION COMMITTEES WILL BE CONSTITUTED. THE MISSIONS OF EACH GROUP WILL BE DEFINED. AT THE END OF THIS EXPLORATORY PHASE, WE WILL BE ABLE TO BEGIN A SCIENTIFIC WORK ON GOOD BASES.

Fields of science (EuroSciVoc)

CORDIS classifies projects with EuroSciVoc, a multilingual taxonomy of fields of science, through a semi-automatic process based on NLP techniques. See: The European Science Vocabulary.

Keywords

Project’s keywords as indicated by the project coordinator. Not to be confused with the EuroSciVoc taxonomy (Fields of science)

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Call for proposal

Procedure for inviting applicants to submit project proposals, with the aim of receiving EU funding.
