This invention is directed to electrodialysis, electrochemical cell and membrane cell equipment particularly to components comprising the ion exchange membranes. These membranes are fabricated with the polymer containing occluded particles of activated carbon. The activated carbon lessens the tendency for membranes, especially the anion selective type, to foul when employed in the electrodialysis of solutions containing fouling constituents. The membranes are obtained by polymerizing a mixture of a liquid monomer and activated carbon particles.
