Abstract: A foam removal apparatus for a vessel which contains a liquid as well as foam bubbles has a cover inclined with respect to the horizontal, a screen, and a trough, the trough being located beneath at least a portion of the screen for removing foam pushed through said screen. The apparatus can be used in conjunction with any shaped vessel and requires no energy for foam removal. Either a rising liquid level in the vessel or a continuous generation of foam forces the foam against the inclined cover and through the screen which causes a substantial amount of foam bubbles to collapse and fall as liquid into the trough.
