A filter assembly for filtering a wash fluid to be circulated by a circulation pump in a dishwasher appliance includes a discharge blade defining lateral, transverse and vertical directions. The discharge blade includes a blade hub and a pair of opposing blades, and each of the opposing blades extend outward from the blade hub to a blade tip along the lateral direction. Further, each opposing blade may include a leading edge, a trailing edge, a top surface, and a bottom surface. The trailing edge of at least one opposing blade may be spaced apart from the leading edge along both the transverse and vertical directions, and may define a curve extending between the blade hub and blade tip along the lateral direction. Still further, the top surface of the at least one opposing blade may define a slope between the leading edge and the trailing edge along the transverse direction.

Systems, apparatuses and methods related to treating and/or recycling a wastewater for reuse are described.

A device and a method for thickening a slurry are disclosed. A pump is provided comprising an inner chamber, a pumping apparatus, an external wall, an inlet, and an outlet. The slurry comprises a solid and a liquid. The slurry enters the inner chamber through the inlet and is pumped and pressurized by the pumping apparatus through the inner chamber across a portion of the external wall comprising a porous wall, causing a portion of the liquid to be pressed through the porous wall as a liquid product stream and thickening the slurry into a thickened slurry stream. The thickened slurry stream leaves through the slurry outlet.

A self-cleaning filter apparatus for a wellbore fluid system includes an outer housing in fluid communication with a source of a fluid via an inlet port, a filter element positionable within the outer housing and including perforations through which the fluid may pass while obstructing passage of impurities, an outlet port provided on the outer housing for discharging filtered fluid from the outer housing, at least one data collection device operable to detect a parameter indicative of a flow of the fluid through the filter element, and at least one scraper blade disposed within the outer housing and engageable with an upstream wall of the filter element to dislodge accumulated impurities from the upstream wall in response to detecting a parameter indicative of a reduction in flow of the fluid through the filter element with the at least one data collection device.

A washing pipe is mounted on a washing guide provided on an outer side of an outer cylinder screen of the screw press and includes a washing pipe body and washing nozzles provided in the washing pipe body and configured to discharge washing liquid flowing from an inside of the washing pipe body toward the outer cylinder screen. A washing pipe swing supporter is configured to support the washing guide to allow the washing pipe to swing between a discharge position and a separation position. The discharge position is a position where the washing pipe is mounted on the washing guide and the washing liquid is discharged from the washing nozzles toward the outer cylinder screen. The separation position is a position where the washing nozzles are farther away from the outer cylinder screen than in a state where the washing pipe is positioned at the discharge position.

Disclosed is a blockage-proof water diversion and drainage device for highway tunnel construction. The device may include an inlet cleaning component, a diversion component connected to a bottom of the inlet cleaning component, a debris collection component connected to an end of the diversion component close to the inlet cleaning component, and a pre-storage component connected to a bottom of the diversion component. An outlet end of the pre-storage component may be connected to the debris collection component. An openable baffle component and a screen plate may be provided inside a main pipe of the diversion component which can transfer filtered sludge and other debris to the debris collection component, keeping the main pipe clean, maintaining the drainage speed of accumulated water, and reducing the frequency of manual cleaning. Additionally, the device can scrape and clean a surface of the screen plate to prevent blocked, thus extending device maintenance time.

This descriptive report refers to an invention patent for the improvement in a metallic filtration body, belonging to the area of filtration equipment components for liquids, particularly the equipment named turbo filter (100), formed by: a filter body provided with intermediate filtration chamber (101), with extreme product inlet (102), lower filtrate outlet (103) and an opposite outlet for solids (104); by the metallic filtration body (1); by a rotor (105), provided with a set of fine step paddles (106), laid out at the turbo filter body inlet; and a set of coarse step paddles (107), laid inside and along the filtration body (1); by washing and counterwashing devices in the filtration body; by a motor device (108) for driving the rotor and others; said metallic filtration body (1) comprising basically two or more sections of the coaxial tubular metallic filtration body (1); by a connection device (20) among the sections of the tubular metallic (1) filtration body; and by a regulation device (60) for the product, within the sections of the tubular metallic filtration body (1).

The present disclosure may include a press screw separator configured for separating solid components from a slurry containing solid and liquid components. The separator may include a housing, a frame arranged in the housing, and a cylindrical screen which is arranged at least partially in the frame. The separator may also include a screw adapted for pressing out the slurry, which screw may be arranged within the screen and mounted so as to be rotationally movable about a longitudinal axis of the screen. The frame may be mounted in the housing without any clearance.

A vapor relief strainer cleaning assembly comprising a turbine and dislodger assembly, wherein the turbine is configured to move a dislodger assembly disposed within a vapor screen relief vessel. Exemplary dislodger assemblies are configured to be powered by vapor or gas and to use excess vapor or gas optionally to dislodge non-condensable contaminants from the filter screen or to facilitate contaminant dislodgement from the inner wall of the filter screen.

A pipeline strainer having a body with a straining element therein. A cleaning tool is disposed in the body to dislodge debris from the straining element. The debris may be removed from the body through a debris drain. The cleaning tool comprises a portion within the body and a portion outside of the body. A handle may comprise the portion outside of the body.
