In this paper we present the first results of the characterization of fouled desalination RO membranes with STEM-EDS. This technique permits to visualize the cross-section of the fouled membrane with taking advantage of the very high resolution of transmission electron microscope (TEM) and getting its chemical composition with the energy dispersive...

This work examines the interaction between organic matter and metal oxides in ceramic membrane treatment and indicate that both size exclusion and adsorption phenomena occur (on surface, inside pores)....

Fouling of RO membranes is examined one at lab scale with the emphasis on investigating the changes in the relative composition of foulant material as a function of running time for a given feed water quality. Fouling characterization was performed by ultra-structural, chemical and microbial analyses. This comparative analysis of fouled membranes h...
