ABSTRACT:
A method of augmenting the separation of immiscible heavier and lighter components of an emulsion including the steps of conducting the emulsion into a treatment vessel, providing an AC voltage source, employing from the source an AC voltage of at least one selected frequency F1to establish at least one electric filed within the vessel through which the emulsion passes, and cyclically modulating the AC voltage with a method of modulation selected from: (a) amplitude modulation; (b) frequency modulation; and (c) combined amplitude and frequency modulation.
