A device for separating oil-in-water emulsions and for regenerating cleaning and degreasing baths by electrocoagulation is disclosed. The device for regenerating cleaning and degreasing baths, in particular by separation in an electrophysical cell (3), is characterised in particular in that at least two independent electrode devices (1, 2) have their own independent and separately adjustable current circuits (7-10). The formation of coagulation seeds and the electrocoagulation process may thus be both independently adapted to operation conditions and optimised. The separate circuits for both electrode devices (1, 2) allow the process to be carried out with a small gap between electrodes, low voltages and high current densities, when coagulation seeds are to be formed on the soluble electrodes (2), and allow the electrocoagulation process on the permanent electrodes (1) to be carried out with a larger gap between electrodes, high voltages, high field intensities, low current densities and little gas generation. |
