The mechanisms of mass transfer under the action of the 
hydrostatic-pressure, temperature, and dissolved-salt concentration 
gradients and electroosmosis in swollen heterogeneous organic materials 
have been considered. Mass transfer is similar to the migration of 
water and solutes in ordinary solutions and represents discrete translational 
displacements of particles. It is accompanied by ion-exchange processes 
and leads to a change in the structure of the material.
