Abstract
Supported gamma-Al2O3 ceramic membranes have been prepared by sol-gel techniques from alkoxide precursors. Permeability and rejection characteristics of these membranes have been used to determine the effect of sol concentration on membrane thickness. Rejection coefficients of poylethyleneglycols of different molecular weights and of several protein streams of possible industrial interest were also determined. Permeabilities were also measured for several feedstocks. Initial studies of protocols for regenerating membranes have been carried out.Keywords
