A separator system (1) and method for separating a mixture including said one or more liquids or semi-liquids and a loose, solid material substantially into liquid and solid phases. The system includes the components of: a compression separator (100) for separating the liquid from the solid material by compression; a vacuum supply (200) for generating suction to draw mixture into the separator via a feed line. The liquids are captured in a collection tank (301) and the solids in a hopper (320).

A filtering plate and a method for making the same and a filtering device having the same are provided. The filtering plate includes: a plate body, integrally formed of metal as one piece; a plurality of holed units, each holed unit penetrating the plate body and including a big hole and a plurality of small holes communicated with the big hole, the small hole being formed by laser processing and having a first end communicated with the big hole and a second end, the first end being greater than the second end in cross-sectional area.

A liquid filtering system for a dishwasher, having a housing defining a filter chamber and configured to be fluidly coupled to a recirculation flow path of the dishwasher, a filter located within the filter chamber and having a first end axially spaced from a second end and defining a filter there between that has a first surface and a second surface, the filter being positioned within the recirculation flow path to filter soils from liquid flowing through the recirculation flow path as the liquid passes through the filter and a flow diverter to aid in cleaning the filter.

A dewatering screw press has an auger within a case and driven by a motor. Influent material is received through an intake into the case near a proximal end of the auger, where it is driven toward a distal output by the auger. While the influent is driven along the exterior of the auger by a first spiraled fin of the auger, the influent passes by mesh screens in the case and the auger. As the influent material passes by the screens, liquids in the material pass through but solids are prevented from doing so. A second spiraled fin, internal to the auger and spiraled inversely to the first spiraled fin, impels liquid received into the cavity of the auger backward toward a proximal output located at the proximal end of the auger.

In a solid-liquid separation apparatus, which comprises multiple movable members and screws that extend and pass through the movable members without contacting the movable members and which dehydrates sludge while conveying same by means of the rotation of the screws, to apply a wringing action on the sludge and increase sludge dehydration efficiency. (Solution) A first movable unit 41 is configured by linking multiple movable members 4A and 4B as a unit with a linking rod 44, a second movable unit 41A is configured by linking multiple other movable members 4C and 4D as a unit with a linking rod 44A, and the movable members 4A and 4B of the first movable unit 41 and the movable members 4C and 4D of the second movable unit 41A are reciprocated with a phase difference.

A washing machine including a tub disposed inside a main body, a drainage pump configured to cause the received water inside the tub to flow to an outside of the washing machine through a drainage passage, a first filter, arrangeable along the drainage passage, to filter out foreign matter equal to or greater than predetermined size from the water, and a second filter, arrangeable along the drainage passage, to filter out foreign matter smaller than the predetermined size from the water. The drainage passage includes a first connecting hose to guide the water to flow from the tub to the first filter, a second connecting hose to guide the water to flow from the first filter to the second filter, and a drainage hose to guide the water to be discharged from the second filter to the outside of the washing machine.

A fluid filtration device is provided that can be used for separating solids from fluids. In some embodiments, the fluid filtration device comprises a hollow housing and a hollow filter assembly located within the housing. Fluid to be filtered is provided to the inside of a filter material in the filter assembly and passes outward toward the housing. In some embodiments one or more flow-directing features are located between the filter assembly and the housing, and may aid in the flow of fluid to a filtered outlet after passing through the filter. The flow-directing features may comprise, for example, channels that extend the length of the filter.

A liquid filtering system for a dishwasher, having a housing defining a filter chamber and configured to be fluidly coupled to a recirculation flow path of the dishwasher, a filter located within the filter chamber and having a first end axially spaced from a second end and defining a filter there between that has a first surface and a second surface, the filter being positioned within the recirculation flow path to filter soils from liquid flowing through the recirculation flow path as the liquid passes through the filter and a flow diverter to aid in cleaning the filter.

A system and a method for removing solid buildup from a filter media is disclosed. A slurry is passed parallel across a cross-flow filter, the filter comprising a conductive filter media and the slurry comprising a carrier liquid and solids. A portion of the carrier liquid crosses through the filter media as a permeate while a thickened slurry continues parallel to the filter media. A blockage of at least a portion of the filter media is detected. The blockage comprises a portion of the solids. At least a portion of the filter media is heated to a melting temperature of the solids, such that a portion of the blockage melts, whereby the blockage is cleared.

A food processing apparatus includes a pressure vessel defining a compartment having an inlet end for receiving food product and an outlet end for discharging food product, an open-top screen mounted within the compartment and movable relative to the compartment between a first position, for food processing, and a second position, to facilitate cleaning, a rotatable auger mounted such that at least a portion of the auger is within the screen, the auger being operable to advance food product within the compartment from the inlet end of the pressure vessel toward the outlet end, and a transfer mechanism including a conduit in communication with the compartment, a fluid discharge positioned substantially within the conduit, and a pressurized fluid source in communication with the fluid discharge and operable to propel a fluid through the fluid discharge to move food product through the conduit.
