Abstract
Method and apparatus for separating immiscible solid or liquid particles such as oil from a liquid-based mixture or emulsion. The apparatus consists of two spaced apart concentric elongated metal cylinders. The wall of the innermost cylinder contains a multiplicity of spaced apart radially bored holes and its exit end is capped. The outer surface of the innermost cylinder and the inner surface of the outer cylinder consists of an alloy of copper and nickel. Liquid is pumped under pressure into the innermost cylinder causing a multiplicity of jets of liquid to issue from the holes in the inner cylinder wall to bombard the copper-nickel surface of the inner wall of the outer cylinder. Electrons freed from the copper in the wall combine with both liquid molecules and particle molecules, causing the particles to separate from the liquid.
