An endless elongate structure adapted to circulate around a path. The endless elongate structure comprises a central longitudinal portion and two lateral longitudinal portions on opposed sides of the central longitudinal portion for supporting the central longitudinal portion therebetween. The central longitudinal portion and two lateral longitudinal portions are connected together by joiners. The central longitudinal portion is adapted to be assembled into a movable tubular formation which is adapted to be continuously assembled at one end thereof and continuously disassembled at another end thereof during movement of the elongate structure along the path. The central longitudinal portion has two longitudinal edge sections adapted to be releasably connected together for assembling the tubular formation by a slidably interlocking connector. The slidably interlocking connector is integrated with the two longitudinal edge sections by joiners.

A solid-liquid separation device of the present invention is a solid-liquid separation device, in which a filtration belt (1), a seal belt (8), and a squeezing belt (15) are wound around an outer circumference of a separation roll (7) rotated in a circumferential direction and are able to run along a rotational direction of the separation roll (7), an object (P) to be processed supplied between the filtration belt (1) and the seal belt (8) is sandwiched between the filtration belt (1) and the seal belt (8) on the outer circumference of the separation roll (7) and squeezed by the squeezing belt (15), and the object (P) to be processed is dehydrated by being ventilated by ejecting a ventilation gas toward a radially outer side of the separation roll (7) via a ventilation gas chamber (10) formed in an inner circumferential portion of the separation roll (7), in which the seal belt (8) is a woven fabric of multifilament or a woven fabric obtained by combination of multifilament and monofilament and is a thinner than the squeezing belt (15).

A pressing device having an endless conveyor which includes conveying elements connected to each other to form and endlessly revolving track. Adjacent conveying elements are pivotally connected together via pins forming pivot axes. A press roller is provided in a pressing zone to apply pressure to the material to be pressed, which is conveyed on the endless conveyor. Adjacent conveying elements of the endless conveyor have intermeshing fingers, and the pin connecting the conveying elements penetrates these fingers, such that in the pressing zone the conveying elements assume a pivot position with respect to each other in which the outer side of the endless conveyor forms a closed, plate-like surface without protrusions of recesses. The pressing zone follows a break open zone in the circumferential direction of the endless conveyor, and in the break open zone the endless conveyor is deflected such that the outer side thereof is concavely bent.

An effluent collector includes a filtrate receiving portion having a filtrate opening, and a pressate receiving portion having a pressate opening. The effluent collector includes a diverter barrier adjustably positioned above the pressate receiving portion. The diverter barrier is configured to adjustably direct at least a portion of a flow path toward or away from the pressate receiving portion.

A sludge dewatering system includes: a concentration apparatus that concentrates sludge while conveying the sludge on a top surface of a filter body; and a dewatering apparatus that subjects the sludge discharged from the concentration apparatus to pressure dewatering. The concentration apparatus includes: a filtering unit that subjects the sludge, which has been added with a first chemical agent, to gravity filtration; a chemical feeder that adds a second chemical agent to the sludge conveyed in the filtering unit; and a moving mechanism that moves the sludge, which has been added with the second chemical agent, in a direction intersecting a conveyance direction of the filter body.

A pair of filter cloths is wound around a first roll a plurality of times by being wound around the first roll, then being wound around a second roll to return to a space between the first roll and the pair of filter cloths wound around the first roll, and being wound around the first roll again. The pair of filter cloths wound around the first roll the plurality of times applies a pressing force to the first roll.

An effluent collector includes a filtrate receiving portion having a filtrate opening, and a pressate receiving portion having a pressate opening. The effluent collector includes a diverter barrier adjustably positioned above the pressate receiving portion. The diverter barrier is configured to adjustably direct at least a portion of a flow path toward or away from the pressate receiving portion.

An apparatus for performing an operation on a fluid material to separate liquid from solid matter within the fluid material The apparatus comprises a belt structure movable along a path. The belt structure comprises a belt portion adapted to be assembled into a movable tubular structure within which at least part of the operation is to be performed. The tubular structure is permeable to liquid for separation of liquid from solid matter within the fluid material. The tubular structure is continuously assembled at one end thereof and continuously disassembled at another end thereof during movement of the belt structure. The path includes a descending portion along which the assembled tubular structure passes, the descending portion being inclined whereby at least some of the solid matter within fluid material in the tubular structure is caused to move downwardly along the descending portion under the influence of gravity to facilitate cleaning of the permeable tubular structure.

The invention relates to a filter medium having a filter fabric on an upper side and a support fabric on a lower side, wherein the filter fabric and the support fabric have different yams and together take the form of a double weave, wherein the filter fabric has a pore count of 4000/cm2 or greater, preferably 5000/cm2.
