The invention provides a method of separating the components of a liquid/liquid dispersion or emulsion, comprising the step of applying simultaneously to the dispersion or emulsion both an electric field and an aligned centrifugal force, in such a way as to set up a bulk interface at right angles to the direction of the electric field and centrifugal force, the bulk interface being located within the electric field between the dispersion or emulsion and one separated component thereof. The combined effects of the electric field and centrifugal force break the liquid emulsion, preventing the formation of a sponge layer at the interface and hence allowing more effective separation of the components than has previously been possible. The invention also provides apparatus for carrying out the claimed method of separation.
