  • Apparatus for automatically recovering grease from a grease separator
    Patent number: 5705055
    Abstract: An apparatus for separating grease from an effluent stream containing grease and water includes a separation tank, having a separation chamber; in which the grease and water in the effluent separate with the grease floating on top of the water. Grease is heated to a liquid state then pumped from the separation tank when the depth of the grease has reached a predetermined depth below an upper surface of the effluent in the separation tank. The pumping of grease from the separation tank is interrupted after a predetermined period of time. Separated water passes through a relatively low passage to a trap chamber which has a water outlet.
