Apparatus is disclosed for separating sludge, oil and the like from contaminated water having walls separating a tank into first and second compartments. The tank has an inlet for carrying the contaminated water thereto, a first outlet for removing separated oil and the like, a second outlet for removing the treated water and an outlet for removing separated sludge and the like. A plate pack is mounted on an inclined wall within the tank with the pack sloping downwardly from a first to a second end. The improved pack includes side walls, a top and a bottom forming a conduit for carrying the contaminated water from the first to the second end. A plurality of plates is mounted one above the other extending between the side walls to provide a plurality of passageways. The plate pack second end defines a substantially vertical plane when the pack is mounted on the inclined wall. The contaminated water passes from the first to the second compartment by flowing down through the passageways and the oil separates from the water during such passage to rise and flow out the first end and the sludge separates from the water to settle and flow out the second end.
