  • Patent number: 5512171
    Abstract: This invention relates to a separator device for the separation of fine particles from a contaminated liquid. The device utilizes the process of electrolysis to produce small gas bubbles which attach themselves to the fine particles and move the particles to the top of the liquid surface where they can be easily removed. The separation is facilitated by the use of baffles which prevent the formation of convection currents in the body of the separator device, and by inclined plates which direct the rising particles towards the removal point.
