Ultrafiltration membranes were obtained by means of modification of microfiltration ceramic membranes with pyrocarbon from polyisocyanate and sodium carboxymethyl cellulose. For Ca 2+ the retention factor and the specific productivity of the modified membranes depend on their composition and filtration time of the solution being purified and vary from 70 to 2% and from 96 to 4.7 dm 3 /(m 2 ·h) ( P —1.1 MPa). The retention factor of direct scarlet dye is 99.99% at the specific productivity from 2 to 19.7 dm 3 /(m 2 ·h) ( P —1.2 MPa).
