Membrane fouling which is a very sensitive issue for membrane application is also a very complex
phenomenon, due to its large variety. There are four main categories of fouling: biological, organic,
colloidal and mineral. The autopsy of membranes which is a destructive analytical method is also an
excellent tool to define very precisely the nature of the deposits. Located in the suburbs of Paris, the
Mry-sur-Oise drinking water plant was extended to a 37 mgd capacity nanofiltration (NF) membrane
process four years ago. Membrane studies, which were carried out in a pilot plant, started five years
before the full scale NF WTP. The objectives were to define the treatment process and the operating
conditions which minimize the risk of membrane fouling. Autopsies have been performed on NF
membranes, which have been used for some weeks or for several years and fed by the process waters of
Mry-sur-Oise WTP. This paper presents all the results of the autopsies performed on NF membranes
stemming from pilot units dedicated to antiscalant testing. Includes 7 references, table, figures.
