Abstract:
A liquid contaminant separation system that includes a liquid surface skimmer having an interior with a wall perimeter sealed by a vertically sliding float. The float has a tubular body with slots in the tube wall, and a vortex cavity in an upper section thereof. The structure of the float provides for flow of liquid from a supply reservoir through the slots in the float wall, over a top edge of the float into the vortex cavity, and then down into the collection reservoir of the float. The float level is determined by the level of liquid in the collection reservoir. Vertical slots in the wall of the collection reservoir extend above the level of liquid in the supply reservoir. The float body must be sufficiently iong so that lower ends of the slots are blocked by the float body. This ensures that liquid from the supply reservoir will flow into the float only at the top edge of the float, thereby enabling the system to effectively separate the desired liquid from the contaminating liquid. After liquid is accumulated in the collection reservoir of the float, the liquid is pumped at a controlled rate from the collection reservoir to a separation chamber.
