A filter for a non-plumbed appliance is provided. The filter includes a filter housing defining a filter chamber. A filter inlet and a filter outlet are positioned along a bottom portion of the filter housing, and filter media is positioned within the filter chamber to remove contaminants from water flowing through the filter media. A divider wall is positioned within the filter chamber to direct the flow of water through a flow aperture at a top portion of the filter chamber, such that the filter chamber remains filled with water during operation. As a result, the filter media remains completely submerged, thereby improving filtration performance, reducing pressure drop, and more evenly depleting the filter media.

Disclosed are filter systems and methods for swimming pools and spas for leaves and other larger debris. The disclosed filtering devices may be provided in-line with a pool cleaning or filtering system such that filtering devices pre-filter the larger debris before the pool cleaning or filtering system filters smaller debris. In some cases, the filtering devices provide an airtight seal that is easy for a user to open or close as desired. In some cases, the disclosed filtering devices include a filter between an inlet and an outlet that are parallel to and offset from a center axis of the filter. In some cases, the filtering devices are configured to generate horizontal cyclonic flow of water.

[Object] A target cell capture filter is provided, having an improved capture ratio per unit area, structured as a filter for extracting and capturing target cells contained in a biological sample such as blood or the like in a simple manner, in a short period of time, and with high efficiency. [Solving Means] A target cell capture filter is structured to have a capture face for capturing target cells in a liquid. The target cell capture filter has multiple notches that allows a part of the capture face to be elastically deformed in a direction that is orthogonal to the capture face, thereby providing gaps. At least part of the plurality of notches are a first notch group including multiple notches designed such that there is a difference between the notches in a shortest distance from a greatest deformation location of the notch to an outer edge of the capture face, and such that the same elastic deformation amount is exhibited with respect to the impulse per unit area.

The present invention relates to a method of cleaning or filtering beer, having the following steps: applying beer onto an obliquely positioned filter (10), so that the beer runs down along the obliquely positioned filter (10) and liquid contained therein passes through openings of the filter (10) into a collecting space (20) beneath the filter (10) and solids contained in the beer slide downwards along the obliquely positioned filter (10), and routing the filtered beer out of the collecting space (20).

The invention also relates to a beer cleaning apparatus.

A filtering device includes a pleated filter that includes a filter base having folds that repeatedly form mountains and valleys and having a cylindrical shape whose direction of an axis is a ridge line direction of the folds and in which the mountains are located outward in a radial direction, an untreated-water nozzle through which untreated water is ejected toward an outer circumferential surface of the pleated filter, a case that includes an outer tubular portion provided so as to surround the pleated filter and including a nozzle opening of the untreated-water nozzle therein, a filtered-water flow path that leads filtered water having passed through the pleated filter from the inside of the cylinder of the pleated filter to the outside of the case, and a discharge flow path through which discharge water that is not filtered by the pleated filter is discharged to the outside of the case. The pleated filter is configured to rotate in a direction about the axis. Ridge lines of the plural mountains of the pleated filter are curved in a shape that expands in a direction opposite to the rotation direction.

Water pumps for an urban water landscape, including a water pump main body, a water pump base, a grille net cover, and a filter component. The water pump main body may include a water pump shell. A water outlet interface may be disposed on a top of the water pump shell. The grille net cover may be located on a front side of the water pump shell. The grille net cover may be fixedly connected to the water pump shell through a filter component pallet on a bottom of the grille net cover and filter component cross bars on two sides of the grille net cover. Two filter assemblies may be inserted in series in the filter component slot. The water pump main body may be detachably disposed on the water pump base.

The present invention provides a multi-structure filtration device for filtering, separating, and dehydrating foreign substances in water, the multi-structure filtration device comprising: a filtration tank filled with filtration target fluid inside; a filtration device unit having a cylindrical double drum structure, installed in the filtration tank so that a part of the filtration device unit is submerged in the filtration target fluid, and including two or more filters having different mesh sizes that are respectively wound on an inside and an outside of the filtration device unit, and one or more washing modules washing foreign substances attached to the filter wound on an outside of the filtration device unit. Accordingly, the multi-structure filtration device can have excellent filtration performance by double-filtering the target fluid using two or more filters, can operate in an eco-friendly manner by recycling filtered water and effectively washing the filters using the filtered water without separate chemicals, can increase the durability of the filters, and can reduce the washing and processing cost by reusing the filters.

A rotary drum filter includes a drum shell configured to rotate through a slurry, the drum shell having areas defining a plurality of drainage holes, at least one divider plate a first end and a second end, the at least one divider plate disposed on an outer surface of the drum shell and extending longitudinally and laterally along the drum shell, the first end being disposed near a drainage hole, and a filter medium disposed on one or more grids that are disposed on the outer surface of the drum shell above the at least one divider plate. The at least one divider plate is configured to direct filtrate on the outer surface of the drum shell filtered through the filter medium into the drainage hole.
