ABSTRACT A sludge-separating apparatus that includes a separation tank for receiving a supply of liquid and sludge from an adjacent holding tank. A pump is utilized for transporting suspended sludge from the adjacent holding tank to the separation tank, with the pump having an inlet in the holding tank and an outlet disposed at the bottom of the separation tank. A baffle plate is disposed in the separation tank adjacent the outlet for deflecting the suspended sludge entering therethrough toward the surface of the liquid held in the separation tank. A divider isolates the separation tank into two regions. The outlet of the pump is in the one region, while the divider allows relatively sludge-free liquid to pass into the second region. A liquid return associated with the second region returns the sludge-free liquid to the holding tank. An automatic skimmer, including a carriage that has a pusher plate mounted thereon, is associated with the first region of the separation tank for skimming floating sludge from the surface of the liquid and discharging the sludge over upwardly inclined end panel bounding the first region of the separation tank. A drive means for reciprocating the skimmer allows both reciprocating motion of the skimmer and tilting and pivoting action of the skimmer as it travels upwardly and downwardly along the inclined end panel. The preferred drive means includes an endless chain trained about -two sprockets, one of the sprockets being rotated by a motor. An actuator ball secured to the chain is captured within a channel secured to the carriage so that the channel is perpendicular to the direction of skimmer travel.
