Provided is a sludge separation and removal device, which suctions and discharges sludge-containing cutting fluid from a supply pipe that supplies sludge-containing cutting fluid into a container. The device is capable of limiting clogging of the filter. The device is provided with: a suction pipe (2) that suctions sludge-containing cutting fluid stored in a storage tank; a filtering unit (3) that separates and removes the sludge from the sludge-containing cutting fluid (Sc) supplied from the suction pipe (2); an efferent pipe (6) that returns the cutting fluid (c) filtered by the filtering unit (3) to the storage tank; and a pumping unit (4) that suctions sludge-containing cutting fluid stored in the storage tank and returns the cutting fluid filtered by the filtering unit to the storage tank. The filtering unit (3) has at least a bottomed circular pipe-shaped first filter (33f) for separating and removing the sludge. The discharging end (2a) of the suction pipe (2) is faced toward the side wall of the first filter (33f) and sludge-containing cutting fluid (Sc) is discharged from the discharging port of the suction pipe (2) at the side wall of the first filter (33f).

Provided is a floating oil recovery apparatus which makes it possible to recover floating oil with a greatly reduced amount of water mixed therein. The floating oil recovery apparatus is provided with: a suction pipe wherein one end serves as a suction port-side end that opens upwardly and the other end is coupled to the intake port of a pump; a float which allows the suction port-side end to follow close to the liquid surface of the liquid in a storage tank; a liquid surface following-type suction apparatus provided with an adjustment pipe which is loosely inserted in the suction port-side end of the suction pipe in such a way that the adjustment pipe can move up and down, the upper end opening edge of said adjustment pipe serving as a suction port; a separation tank into which the oil-water liquid mixture in the storage tank flows for the separation of the oil-water liquid mixture into oil and water; a pump for sucking the oil-water liquid mixture from the storage tank and feeding the oil-water liquid mixture to the separation tank; and a deaerator for removing air from the oil-water liquid mixture sucked from the storage tank.
