NON-EQUILIBRIUM THERMODYNAMICS OF ELECTRO-OSMOSIS OF WATER THROUGH COMPOSITE CLAY MEMBRANES, 2. THE SERIES ARRANGEMENT

In this paper, the electro-osmosis of water through a composite clay membrane consisting of kaolinite and bentonite clay-membrane elements in a series array has been studied and the form of the phenomenological relations ascertained. The electrical flux in the presence of both pressue difference and electrical-potential difference was found to be represented by the usual linear equation. The phenomenological relation for the water flux, though linear, was different from the usual one, because the graphs between water flux and pressure difference, and electro-osmotic velocity and applied electrical-potential difference were found to be straight lines having definite intercepts on the x-axis. The combination rules for membranes in series have been found to be valid only for the phenomenological coefficients representing the hydraulic permeability and not in the case of the other three coefficients representing the electro-osmotic velocity, streaming current and electrical conductivity. The study of directional characteristics of the phenomenological coefficients revealed the anisotropic character of the composite clay membrane in a series arrangement. /AUTHOR/
