A filter cartridge for a household appliance, which is provided with a filter housing, the wall of which separates a housing internal side from a housing external side. A filter inlet opening which in the operation of the filter cartridge is open in relation to the external environment of the filter housing is provided, wherein a device for water conduction which comprises at least one filter chamber having at least one filter medium and terminates in a filter outlet opening for suctioning water from the filter cartridge is provided in the interior of the filter housing downstream of the filter inlet opening relative to the flow direction during operation, and wherein a filter connection element having an annular filter port which has an annular filter fixing face for the tight connection of the filter cartridge to a tank fixing face in the water tank is provided.

A device for washing an article in a container of fluid includes a cover having a wash surface, an opposed undersurface, and multiple ducts extending therethrough, where each of the ducts has an internal wall that tapers outwardly as the duct extends away from the wash surface, and a base operatively coupled to the cover, the base having a support surface and an opposed interior surface positioned facing the undersurface of the cover. The device further includes a resilient member operatively coupled between the cover and the base to bias the cover and base apart. Pushing the article against the wash surface presses the cover towards the base and directs a portion of the fluid through the ducts onto the article. Also disclosed are a wash assembly and a washing system including the device.

A wastewater filter cartridge includes a peripheral frame, two filter media sheets, two sets of angled fins, and a filtered water outlet. The two filter media sheets are attached to the peripheral frame in spaced face-to-face relation such that they combine with the peripheral frame to define an interior volume within the filter cartridge. At the same time, the two sets of angled fins are attached to the peripheral frame external to the interior volume and project away from the filter media sheets at oblique angles. As wastewater passes through the two filter media sheets into the interior of the filter cartridge, the two filter media sheets act to reduce the suspended solids in the wastewater. Once in the interior volume of the filter cartridge, the filtered water is collected via the filtered water outlet, which is connected to the interior volume.

The disclosed technology includes systems and methods for water filtration. In one implementation, a system includes a water receptacle to house unfiltered water, the receptacle including an aperture located in a sidewall, a valve component located on an exterior surface of the sidewall in alignment with a filter housing located on an interior surface of the sidewall filtrate the unfiltered water. In one implementation, a method includes filling a water receptacle with unfiltered water, filtrating the unfiltered water through a filter housing in the water receptacle to obtain filtered water, and moving the filtered water from the filter housing and out of a valve component connected to a first end of a filter housing.

Methods and apparatus providing for the isolation of an unknown mutation from a sample comprising wild type nucleic acids and mutated nucleic acids through the application of time-varying driving fields and periodically varying mobility-altering fields to the sample within in an affinity matrix.
