An outlet piece assembly for a horizontal plate and frame-type filter, such as tower press. The disclosure is based on the idea of providing the outlet piece assembly as having a base removably attachable to a filter press (e.g., to the filter plate or plate frame thereof), and a lid removably fixed to the base, such that an internal conduit of the outlet piece assembly running between a vat end and a discharge end is formed between the base and the lid. This enables a part of an associated filtrate vat component, such as the vat liner, to be received between the base and the lid, thereby ensuring secure sealing between these components.

A filter plate frame assembly with a filter plate frame and a subframe housed within the frame, such that the subframe can be removed from the frame without removing the frame from the filter press. In this way, consumable components can be provided in connection with the subframe, which can be easily removed from the filter press. This, in turn, makes replacement of worn components faster, as the whole frame does not need to be removed from the filter press. An associated horizontal filter press and a method of replacing worn components of such a filter press is also provided.

A filter plate subframe for a filter plate frame assembly having a filter plate frame and a filter plate subframe slidably receivable therein. The subframe comprises separate periphery segments attached to each other so as to form a continuous, generally rectangular periphery region with flank sides and end sides. The flank sides have a linear density lower than that of the end sides, and the end sides have a bending stiffness higher than that of the end flank, while either or both of the first end side and the second end side are provided with a reinforcement bar for increasing the bending stiffness said end sides. A supporting surface is provided on a first planar side of periphery segments forming the flank sides the supporting surface.

A filter diaphragm for a horizontal plate and frame-type filter, such as a tower press, including a sheet like body and at least on a filter plate-facing side thereof, a continuous seal bead. The seal bead includes an inner seal lip on a lateral inside of the seal bead and an outer seal lip surrounding the inner seal lip on a lateral outside of the seal bead. The outer seal lip is elevated from the inner seal lip in a vertical direction perpendicular to a general plane defined by the diaphragm.

A filter element for a filter apparatus includes at least one filter member and a frame member arranged to support the at least one filter member in such a manner that an internal cavity is formed. The filter member includes a permeable membrane layer which has a first filter surface for receiving a pressure and directed towards an internal cavity arranged in-side the filter element, and a second filter surface for receiving solid particles filtered from a feed. The filter member forms a capillary filter.

A vacuum belt filter including a belt with a plurality of vacuum boxes, filter means being arranged to the vacuum boxes, drive means for moving the belt, and a suction station for creating an underpressure to the vacuum boxes at the suction station. In order to enable liquid-solid separation at low energy costs and long service interval of the vacuum belt filter, the filter means is in the form of a capillary filter, each vacuum box being provided with such a filter and each vacuum box being provided with an outlet having a check valve enabling a fluid flow from the inside space of the vacuum box to the outside of the vacuum box for creating an underpressure in the vacuum box when the suction station is connected to the vacuum box.

A ceramic filter plate () is provided with a conductive wiring () extending along the filter plate to form a continuous electrical circuit and arranged to break upon breakage of the filter plate. The integrity of the conductive wiring () is monitored, and the operation, particularly the rotation, of the disc filter is immediately stopped upon detecting a break of the conductive wiring.
