Abstract

The transport behaviour of membranes composed of a parallel array of elements was studied on the basis of two assumptions-the equality of force for all elements and additivity of flow. It was shown that under certain conditions the practical phenomenological coefficients exhibit marked deviations from additivity indicating strong circulation of flow among the membrane elements. The behaviour of such membranes was calculated for a special case based on the Teorell and Meyer and Sievers model. It was found that in a parallel combination of positive and negativ membranes there may develop a marked increase in salt permeability which will also be expressee by a pronounced negative anomalous osmosis.
