A filter device for a water-bearing domestic appliance has a flow-through filter housing with waste water inlet, filtered water outlet and filtrate outlet, at least one panel filter and a mounting therefor in the filter housing, wherein the panel filter has a mesh width and an angle to the horizontal, and a filtrate chamber in the filter housing for collecting filtrate. The panel filter, the waste water inlet and the filtered water outlet are arranged relative to one another such that a flow direction for water from the waste water inlet to the filtered water outlet passes through the panel filter. The filtrate chamber is accessible via the filtrate outlet for removing the filtrate from the filtrate chamber, in particular by backwashing. The at least one panel filter is variable in shape to change its mesh width, and/or an angle of the at least one panel filter to the horizontal can be altered by movement of the panel filter, in particular rotation.

A filtering device and a tableware washing apparatus, the filtering device includes a rotary filter and a drive assembly. The rotary filter includes a columnar filtering screen configured to filter water from a washing process of the tableware washing apparatus; wherein a diameter of an external circle defined by each mesh of the columnar filtering screen is between 0.2 to 0.5 mm. The drive assembly is connected to the rotary filter and configured to drive the columnar filtering screen to rotate relative to contents within the columnar filtering screen at a relative speed of 100 to 1000 r/min, for separating at least a portion of residue on the columnar filtering screen from the columnar filtering screen.

A non-powered drain pump screen device is disposed in a river, a stream, a waterway, or a place in which a significant amount soil is carried by a water flow. Upper and lower impellers are provided with upper and lower blades. The lower blades prevent reentry of impurities while rotating due to resistance to a flow of fluid in a non-powered manner. The upper impellers are rotated in a non-powered manner, so that the upper blades filter impurities. The non-powered drain pump screen device is disposed in a waterway to remove impurities at low maintenance costs.

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.
