As in the first two years of this project, research during the third year covered three major areas: preparation and characterization of supports for the membranes; preparation and characterization of the membranes themselves; and determination of the behavior of systems in which the membranes are attached to supports. The primary interest in supports was to develop formulations which would provide more reproducible permeabilities (flux of water through the support). Several different clay formulations have been shown to give quite reproducible permeabilities, with the actual permeability varying by nearly an order of magnitude among the different formulations. Supports with smoother surfaces were also fabricated, but rejection studies which compared membranes coated on these supports to membranes coated on rougher supports did not show any significant differences. Ceramic membranes have been prepared which are composed of three different materials: alumina, titania and silica.
