Abstract:
An apparatus for electrochemically removing fine metal particles in an oil in water emulsion, the apparatus comprising:a container for accommodating the oil in water emulsion; a supply port for delivering the oil in water emulsion to the container; a plurality of cathode plates and anode plates located in the container in a facing relationship, wherein the water and fine metal particles in the emulsion are electrolyzed to produce hydrogen, hydroxide ions, and metal ions when a predetermined direct voltage is applied between each anode plate and each cathode plate, wherein the hydroxide ions and the metal ions react to form metal hydroxide, and wherein the metal hydroxide and fine metal particles, which are insoluble in the oil in water emulsion, along with sludge, grease and lubricating oil which is the main cause of odor float with hydrogen generated by the electrolysis; and a discharge port located in the lower of the container for discharging emulsion from which the metal hydroxide and the insoluble fine metal particles have been removed.
