A high-pressure filter is provided, which belongs to the field of filter device technologies, and comprises a trough, a filter disc, a power device, a spiral stirring device, and a compressed air storage tank. A sealed housing is disposed outside the trough, and an inner wall of the sealed housing is connected to an outer wall of the trough to form a sealed cavity. The compressed air storage tank is in communication with the sealed cavity, and compressed air is supplied to the sealed cavity to form a high pressure environment in the sealed cavity. Therefore, a pressure difference is formed between the interior and the exterior of the filter disc to improve the filtering efficiency.

A rotary disc filter includes one or more filter discs secured to a rotary drum and include a series of circumferentially spaced backwash guides disposed in the filter disc. During backwashing, the backwash guides function to engage a mixture of backwash and suspended solids and guide or direct the mixture to a sludge trough disposed in the disc filter. The backwash guides generally assure that a greater percentage of the backwash and suspended solids mixture end up in the solids trough.

A modular support structure comprising multiple chord or arc modules configured to selectively fixedly engage adjacent modules to define a completed annular support structure configured to support a rotary element of a rotary filter. The modular chord or arc segments may fixedly engaged an adjacent chord or arc segment through a fixing mechanism selected from the group consisting of: fasteners, clamps, pins, bolts, locks, locking mechanisms, key and socket mechanisms, spot welding, welding, adhesives, and other fastening mechanisms configured to engage and disengage adjacent chord or arc modules with ease.

The invention relates to a system for detecting damages of filter fabric (8) with continuous disc filters (1) where the system comprises of pressure sensor element (41) that is attached into a filter sector (5) so that it measures the pressure inside (11) the filter sector and is connected with a CPU (42) and a radio unit (43) that periodically transmits the measured pressure values to a receiver (R) that receives the transmitted measurements and compares the measurements using processing means (55) with previously received values and detects damages by detecting significant pressure difference.

A filter includes a filter assembly deployed within a pressure vessel. The filter includes a series of filter configurations arranged along a central flow path connected to an outlet. Each filter configuration has filter screens overlying at least one filtrate channel which directs filtered fluid to the central flow path, A partition is deployed within the pressure vessel so as to subdivide the pressure vessel into a first filter chamber and a second filter chamber, each containing a number of the filter assemblies. A flow diverter is deployed in the central flow path for diverting a flow of filtered liquid passing along the central flow path from the first filter chamber so as to flow outwards from the central flow path to undergo a second filtering in the second filter chamber. Also disclosed is an outlet flow throttling arrangement to avoid overload of a backwash cleaning system.
