Abstract

The invention comprises a device and a method for electrostatic coalescence of fluids. The device comprises a housing (110) having a fluid inlet (111) and outlet (112), electrodes (1; 2; 3) located within the housing and exposed to the fluids. According to the invention at least one electrode (1; 2; 3) comprises several electrode segments. The method is characterised in that it comprises applying a DC and/or a pulsed DC and/or an AC field in the fluid by means of segmented electrodes.
