A vacuum belt filter device includes an endless moving filter belt, a vacuum arrangement having a vacuum box having suction openings, and a guide part on opposite sides of the suction openings. Each guide part is arranged between the vacuum box and the endless moving filter belt. Each guide part has a first groove, and an endless seal belt configured to run in the first groove in contact with the low pressure side. A detachable wear strip is arranged in the first groove of each guide part between the endless seal belt and the guide part.

The invention relates to a pressing device (1) with an endless conveyor (2) which comprises a plurality of conveying elements (3) which are connected to each other in an endless circulating link and adjacent conveying elements (3) are pivotably connected to each other in each case via a pin (10) forming a pivot axis, and with at least one press roller (7) which is provided in a pressing zone (PZ) in order to apply pressure to the material to be pressed, which is conveyed on the endless conveyor (2), between the press roller (7) and the endless conveyor (2). According to the invention, the pressing device (1) is characterized in that adjacent conveying elements (3) of the endless conveyor (2) have intermeshing fingers (8, 9) and the pin (10) connecting the conveying elements (3) penetrates said fingers (8, 9), and that in the pressing zone (PZ) the conveying elements (3) assume a pivot position with respect to each other in such a way that the outer side of the endless conveyor (2) in this region (PZ) forms a closed, plate-like surface without protrusions or recesses, and that the pressing zone (PZ) follows a break open zone (ABZ) in the circumferential direction of the endless conveyor (2), in which break open zone (ABZ) the endless conveyor (2) is deflected in such a way that the outer side thereof is concavely bent (cf. Fig. 2).

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.

A screening system comprises a tank (20) containing a sewage screen (30), wherein the tank is configured for attachment to a sewage channel, and to receive sewage flow from an upstream point of the channel, and then to direct the sewage flow through the sewage screen (30), and then to return the screened sewage flow back into the channel, at a downstream point, or directly to a downstream treatment, and wherein the tank (20) is configured to decrease the velocity of the sewage flow in the tank relative to the channel, such that grit can settle at the bottom of the tank, and wherein the sewage screen (30) comprises a working screening surface (31), a portion of which lies in a substantially horizontal plane, and is positioned below the invert level of the sewage channel at the upstream point, when in use. Screen and tank used within the before mentioned system as well as the method of screening sewage using the system are also disclosed.

This invention relates to a sieve cloth and a method of connecting the sieve cloth to a sieve apparatus having an endless sieve cloth supported by a support belt which, in operation, is structured to rotate around at least two spaced-apart turning rollers. The method includes the steps of providing at least one sieve cloth sheet having an upper side, a lower side, two side portions and a first end portion and a second end portion extending between the side portions; bringing at least a portion of the sieve cloth sheet into engagement with a portion of the support belt; positioning the sieve cloth sheet against the support belt by moving the support belt around the turning rollers; bringing at least two adjoining end portions into engagement with each other until the at least one sieve cloth sheet forms an endless sieve cloth.
