Abstract
Sludge removal apparatus is provided for new or existing spray coating booths, degreasing tanks, phosphate tanks, plating tanks or the like to remove sludge from the surface of a liquid in the tank. Preferably, a sludge removal tank is disposed adjacent the water holding tank of the coating booth and communicated therewith through an inlet opening. Water jets in the holding tank are directed at the inlet opening creating a current which carries floating sludge to the removal tank. Preferably, air is entrained into water and aids in floating particles. The bottoms of the tanks are preferably swept by water to remove particles settling to the bottom of the tanks. A reciprocating skimmer pushes floating sludge from the sludge removal tank up an inclined beach and into a collection bin.
