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 device and a method for filtering viscous or highly viscous liquids, in particular plastics melts, includes use of an oscillating filter plate.

The invention is related to a method and vibratory apparatus for the improved solid-liquid filtration of filter cakes, especially for dewatering finely divided thixotropic filter cakes, with the aid of a vibratory apparatus. Further, the invention relates to a filtration apparatus having a vibratory apparatus as described herein, and to the use of the vibratory apparatus for the solid-liquid filtration of filter cakes.

A processing system for a slurry material. The system has a vibratory screen disposed atop an open-topped tank. A travel path for a vehicle is disposed directly above the screen and the tank. Slurry material dumped from the vehicle onto the screen is separated at the screen into a particulate-rich stream and a fluid-rich stream. The fluid-rich stream may be pumped to a cleaner so that it may be stored and re-used as drilling fluid. The screen may be a conveyor which removes the particulate-rich stream from above the tank.

The present technology is directed generally to fluid treatment systems. In particular, several embodiments are directed toward filter supports configured to be positioned adjacent a filter belt within a filter belt filtration system. In one embodiment, the filter support can have a longitudinal axis generally parallel to the direction of movement of the filter belt. The filter support can include a plurality of struts spaced apart by a plurality of openings, and at least one of the plurality of struts extends across a portion of the filter support such that a longitudinal axis of the at least one strut is positioned at an angle with respect to the longitudinal axis of the filter support.

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.
