Abstract

An apparatus is provided herein for separating a light liquid (e.g., grease) from a heavy liquid (e.g., water] in a mixture of such liquids. The apparatus is provided with enhanced gravitational separation of such liquids. The apparatus includes a separation chamber for receiving the mixture of liquids, the separation chamber being defined by a plurality of walls and a separation chamber bottom. The separation chamber includes an inlet section, the inlet section comprising an inlet port for introducing the mixture of liquids into the separation chamber. The apparatus includes a level control for maintaining a pre-selected fluid level of the mixture in the separating chamber. The apparatus includes a discharge section, the discharge section comprising a first exit port for removing the light liquid from the separation chamber, the first exit port being positioned near the top of a wall of the chamber. The first exit port comprises a slat. An enclosure, which is connected to the outside of the apparatus, encloses the slot, the enclosure being connected to a second conduit through which the light liquid is discharged. The apparatus includes a downstream section, the downstream section comprising a second exit port in a downstream section of the separation chamber for removing the heavy liquid from the separation chamber. The apparatus includes a heater element which is operatively-associated with the separation chamber, the heater element being capable of heating the mixture of liquids which is contained in the separation chamber. The apparatus includes a skimmer which is suspended in the separation chamber by means of a rotatable shaft which is connected to the separation chamber. The skimmer is configured to direct the light liquid to the first exit port. The skimmer comprises at least one blade which is capable of moving the mixture of liquids, the skimmer being positioned to rotate in substantially the same plane as the first exit port, the plane being parallel to the fluid level. In a preferred practice of an aspect of this invention, a skimmer and a series of liquid flow obstacles are also employed along the heater element to achieve optimal separation.
