Abstract

Application of laser interferometry allowed visualization the process of formation and development of
the hydrodynamic instability at the boundary with cation-exchange membrane in a wide range of current
densities. The study of hydrodynamic state in solution at the interphase boundary demonstrated that in the highintensive
current modes the values of the normal components of the flow rate for hydrodynamic pulsations
supplying substance from the bulk of solution to the surface of membrane and intensifying mass transfer were
comparable with supply flow rate of solution into membrane passage flow.
