    摘要： The present technology relates generally to fluid filtration systems. In particular, several embodiments are directed toward compartmentally expandable rotating belt filters and associated systems and methods. In some embodiments, for example, a filtering system for contaminated fluid includes a first fluid filtering chamber having a first filter belt movably positioned therein and a second fluid filtering chamber having a second filter belt movably positioned therein. The first filter belt can be operable in parallel with the second filter belt. The system can further include a sensor configured to sense a condition related a volume of the contaminated fluid, a speed of flow of the contaminated fluid, or a level of contaminants in the contaminated fluid. A controller can be configured to initiate, stop, or adjust fluid flow to the first fluid filtering chamber and second fluid filtering chamber individually in response to the sensed condition.

    摘要： An apparatus for effecting separation of liquid from solids or solids from liquid comprising a frame supporting a belt or belts held by and between rollers with drive means so as to progress each belt through a collection zone to a compression zone, where at the collection zone the belt or belts are positioned and orientated and shaped and caused to be changed in shape from an upstream position to a downstream position, providing thereby a supporting shape to hold liquid, one part of which shape is defined at a downstream location by a coming together of facing surfaces of one or more of the belts.

    摘要： A pulp-filter arrangement (1) comprises a rotatable drum (10) and a non-rotating valve arrangement (30). The rotatable drum (10) has a cylindrical water-permeable pulp-supporting shell (14), a plurality of drain pipes (16) and a rotating hollow shaft (18). The plurality of drainpipes (16) connects the rotating hollow shaft (18) with a collecting channel (22) situated radially directly inside the cylindrical water-permeable pulp-supporting shell (14). The non-rotating valve arrangement (30) is disposed within the rotating hollow shaft (18) for sealing off the rotating hollow shaft (18) from a radially inner outlet (24) of the drain pipes (16) when respective radially inner outlet (24) is situated within a sealed zone. The non-rotating valve arrangement (30) is further arranged to, in a transition zone immediately following the sealed zone, open a throttled passage between the rotating hollow shaft (18) and the radially inner outlet (24).

    摘要： Disclosed herein are a method and apparatus for removing liquid from a permeable material, such as slurries, sludges, porous solids and permeable foams. The method and apparatus involve constraining the material to be deliquified such that the material interfaces with at least one surface which is permeable to the liquid to be removed and then heating the material at one or more locations remote from the permeable surface or surfaces. Such constraining and heating of the material causes the in situ vaporization of the liquid in the vicinity of the remote location or locations. The vaporized liquid expands and forces at least some of the remaining unvaporized liquid through the permeable surface or surfaces. Because only a portion of the liquid contained in the material must be vaporized and such vaporized portion is used to remove at least some of the remaining unvaporized liquid (thereby avoiding the necessity of vaporizing all of the liquid contained in the material), significant reductions in the energy required to substantially deliquify the material may be realized through the use of the method and apparatus disclosed herein.
