Abstract
An apparatus electrochemically removes fine metal particles from an oil in water emulsion. The apparatus has a container for accommodating the emulsion. A supply port supplies the emulsion to the container. A plurality of cathode plates and anode plates are located in the container to face each other. The water in the emulsion is electrolyzed when a predetermined direct voltage is applied between the plates. The fine metal particles float with hydrogen generated by the electrolysis. Al(OH).sub.3 attaches to H.sub.2 bubbles. A discharge port is located in a lower part of the container for discharging the emulsion from which the fine metal particles, sludge, oil and greese have been removed.
