The procedure for purifying water polluted by oil in emulsion form consists of passing the water in a tank (1) between electrodes (3, 4) so that the current destabilizes the bonds between surfactants and oil molecules, and the oil molecules can float to the surface. The procedure for purifying water polluted by oil in emulsion form consists of passing the water in a tank (1) between electrodes (3, 4) so that the current destabilizes the bonds between surfactants and oil molecules, and the oil molecules can float to the surface. The floating oil layer (5) is evacuated through an aperture (7), while the water from which the oil has been removed is drawn off at a lower level through an outlet (6) into a compartment (11). The water then passes through a passage (16) at the bottom of the compartment into a second compartment (13) and removed through a spillway (2) in the form of an orifice of variable height.
