Abstract of the Disclosure Foam is produced electrolytically in a liquid having foaming tendencies through the use of closely spaced electrodes of opposite polarity that are disposed in substantially upright dispositions within the body of liquid being treated. The electrodes extend from a position deep within the body to a point at or above the surface of the body, and the electrodes are so formed or are associated with such other structure that bubbles generated within the columnar treating region between the electrodes cannot escape from the electrodes until reaching the surface of the liquid, thereby being confined and exposed to the electrodes throughout the full extent of travel by the bubbles to the surface. By regulating the positions of the bubble outlet relative to the surface of the liquid, the characteristics of the foam produced from the bubble discharge may be varied, e.g., locating the point of bubble discharge a very slight distance above the surface of the liquid produces a creamy, relatively viscous foam having small diameter bubbles compared to the foam produced with the discharge at a more elevated position in which instance bubbles of larger diameter appear in the foam.
