Abstract: A piston press in which hydraulic lines (32) of a hydraulic cylinder (19) move a ram plate (21) up and down with relatively large diameters, and in which use is made of a hydraulic pump (33) with a continuously adjustable delivery flow, in particular with constant output regulation, making it possible to move the ram plate (21) more quickly in the unloaded or less loaded state, by which means the operating time is shortened considerably as compared with known piston presses (10).

Abstract: An apparatus for removing liquid from a composite mixture of liquid and solids comprises a hopper mounted atop a compactor ram assembly. A snout section and an extruder section are mounted axial to the compactor ram assembly. A hydraulically-operated ram compresses wet material into the snout and extruder sections. Under pressure from the ram, liquid in the waste material escapes from drainage holes in the snout section top, bottom, and sides, and the extruder section top, bottom, and sides. A platen, pivotally mounted to the extruder top plate near the exit of the device and biased with a constant pressure, controls the back pressure in the extruder and snout sections. The apparatus has an extruder section and snout section of the same constant cross section and coaxial with each other. In a second embodiment of the apparatus, certain of the walls may diverge to further facilitate access to the first platen through the exit opening.

Abstract: According to a waste water treatment method and apparatus of the present invention, a permeable sheet 3 is fed into a treatment tank 2 in which a stream is formed. The waste water, which flows downstream, is caused to pass through the permeable sheet 3, while the permeable sheet 3 travels in the treatment tank 2 so as to traverse the surface of the waste water on a downstream side in the flowing direction of the waste water. Therefore, not only the sludge in the waste water but also the oily substances floating in the waste water can be collected and removed because they cling to the permeable sheet 3 and are gathered by it. As a result, a waste water treatment tank 2 and the like can be maintained in a usable state for a long time. In addition, there can be obtained a treated water to which microbial treatment can be applied.

Abstract: In a method and apparatus for removing water from sludge the sludge is introduced into an intermediate chamber from which it is fed into at least one sludge chamber having a filter surface. A hydrostatic pressure is built up in the sludge chamber to remove the water. The sludge chamber is then opened and the filter surface moved out of the sludge chamber to remove the filter cake.

Abstract: A metal shavings and chips compactor for extruding oil from metal chips and shavings and compacting the metal into easily transportable pellets. A compactor cylinder contains a piston and has an opening through which an auger feeds metal chips and shavings. A gate closes an end of the cylinder. A first hydraulic drive drives the piston under low pressure to close the opening and apply a first compacting pressure on the metal to form a loosely compacted pellet in the cylinder. High pressure then operates the piston to form a compact metal pellet substantially void of interstices. A second hydraulic drive opens the gate; the piston is operated at low pressure to discharge the compact metal pellet from the chamber and oil is collected below the cylinder. The compacting pressures are achieved through mechanical advantages provided by the size of the piston to that of the first hydraulic drive.
