Separation of Dispersed Particles from Oil-in-Water Emulsions Impressed with Voltage

Abstract

A particle in an emulsion has ζ-potential. Therefore, electrophoresis can be used to increase the separating rate of dispersed particles. Emulsions containing very fine particles which are very difficult to separate from emulsions are effectivelly separated to two phases by impressing voltage on these emulsions.
In order to apply the above-mentioned characteristics to actual separator, it is very important to obtain the data for this method.
In these studies, characteristics of the separation of dispersed particles from emulsions are investigated for batch operation and continuous operation. Benzene, kerosene, aniline and nitrobenzene-in-water O/W emulsions are used for these experiments.
As the result, very excellent separating efficiency was obtained by impressing voltage on emulsions.
