Abstract
The scum removal system for liquids is adaptable to wastewater treatment facilities, aquaculture facilities, oil spills, and/or other environments where the removal of a thin, buoyant layer of material from a liquid surface is desired. The system incorporates a geyser pump having one or more inlet pipes, with the inlet pipe(s) collectively having a larger diameter than the discharge pipe. This assures that the volume of water in the inlet pipe is always less than that in the discharge pulse, thus assuring that a steady, constant flow of liquid flows into the inlet opening to assure a uniform inertial flow of the floating contaminants into the inlet. The top of the inlet pipe(s) may be vertically adjustable for variable liquid level. The geyser pump may be submerged within the liquid or may be installed external to the liquid tank with the submerged inlet pipe communicating with the external pump.
