Abstract
A sludge-separating apparatus including a separation tank for receiving a supply of liquid and sludge from an adjacent holding tank. A pump having an outlet disposed at the bottom of the separation tank transports suspended sludge from the adjacent holding tank to the separation tank. A baffle plate disposed in the separation tank adjacent the outlet deflects the suspended sludge entering therethrough toward the surface of the liquid held in the separation tank. A divider in the separation tank allows relatively sludge-free liquid to pass into one of the regions defined by the divider. A liquid return returns the sludge-free liquid to the holding tank. An automatic skimmer is associated with the sludge-containing region of the separation tank for skimming floating sludge and discharging the sludge over an upwardly inclined end panel. 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.
