Ceramic membranes with an asymmetric structure were obtained by deposition of a heterogeneous polydisperse suspension of reduced hydrophilicity on an aluminosilicate substrate. The average pore size of ceramic membranes is 0.3 - 0.5 microns. The problem of matching the shrinkage of the ceramic substrate and membrane layers has been solved. The technology of obtaining micro- and ultrafiltration membranes using suspensions based on aqueous and alcohol-aqueous solutions of carboxymethyl cellulose is presented.
