Pyrocarbon modification of microfiltration ceramic membrane from aluminum oxide by carbonization of polyisocyanate has been carried out. The structure of pyrocarbon was regulated by means of water, glycerin and nickel chloride. Water of purified of dyes by pressure-driven method at the pressure in the range 0.5–1.1 MPa. The retention coefficient and specific capacity of modified membranes for direct scarlet varies respectively from 84.3 to 99.99% and from 0.8 to 32.5 dm 3 /(m 2 •h) and brilliant green—from 45 to 99.99% and from 2.5 to 8.8 dm 3 /(m 2 •h) and they are determined not only by working pressure, but the structure of pyrocarbon too.
