Abstract
PURPOSE: To enhance the vacuum dehydration capacity of a title apparatus by a mechanism wherein a duct comminucated with a filter chamber of a filter material bottom surface is connected to a vacuum tank through a first openable valve and to a pressurized fluid supply system through a second openable valve and both valves are selectively opened and closed.
CONSTITUTION: The sludge completely molten in a freezing and melting tank 10 is introduced into a receiving tank 18 by opening an exhaust valve 12. In this tank 18, the molten sludge is naturally precipitated and is layered to a sludge A with large particles, a sludge B with small particles and water C successively. Subseqnently, a vacuum pump 32 is operated to recover water in a receiving tank 18 to a tank 30 through a vacuum tank 30, a duct 26, a filter chamber 24 and a filter material 22. The recovered filtrate is appropriately exhausted to the exterior portion. When the layer B is clogged and the dehydration becomes impossible, a vacuum pump 32 is stopped, a first openable valve 28 is closed and a second valve 36 is opened to pass a pressurized fluid of a pressurized fluid supply source 38 through the layer A, B, thereby water passing pores are formed. Thereafter, a valve 36 is clossed and a value 28 is opened to operate a pump 32 and a good dehydration is carried out.
