Zeolites are crystalline aluminosiUcates characterized by a structure comprising a three-dimensional pore system and regular framework formed by linked TO4 tetrahedral (T = Si, Al) with different morphological and physico-chemical properties. Due to their impressive selectivity and uniform pore structure, they have very efficient molecular sieving properties, and are able to separate molecules based on size and shape. Zeolite powders, films and membranes are widely used in catalysis, adsorption and separation applications (McLeary et al, 2006 Pina et al., 2011). Zeolites are cheap and widely available due to their abundance in both natural and synthetic forms. The application of zeolites in the membrane field is growing very fast, and has been the subject of increased research focus during the last few decades (McLeary et al., 2006).

Due to low water contents, high specific surface areas and pore structures (see the previous section), the water-rock interactions within the Tournemire shales must be characterized by strong short range (nanometre-scale) water (or solute) molecules-mineral interactions. Therefore, the physico-chemical characteristics of the water and its solutes will be different from that of free water which is conventionally considered to take part in water-rock interactions (Horseman et al. 1996). The difference arises from factors such as the very low mobility of water in thin films, the high suction potentials developed owing to water-mineral surface electrostatic interactions and the membrane filtration of anions. The 9% porosity given above must be considered as a maximum value since waters bound chemically to mineral surfaces are included in the estimates in reality free waters are of most importance to the present study.
