Tubes 13 are provided with flow apertures 11 which are large enough to allow the passage of water and soil particles. The tubes 13 each have an inner space 17. The tubes 13 each hold one of the filter sheets 5 in their inner space 17. A first part of the flow apertures 11 is facing the first side 7 of the filter sheets 5 and a second part of the flow apertures 11 is facing the second side 9 of the filter sheets 5, defining in each tube 13 a flow path 19 for ground water from the first part of the flow apertures 11 through the filter sheet 5 to the second part of the flow apertures 11.

A device for providing purified water from a silt-laden source water having an upper canister, a lower canister, and a filter mounted in the upper canister; wherein the upper canister and the lower canister are fluidly connected via the filter; wherein pre-filtered water is collected in the upper canister and purified water is collected in the lower canister; wherein a pre-filter is fluidly connected between the source water and the upper canister; wherein the pre-filter has a pre-filter canister having an inlet for source water and an outlet for pre-filtered water; wherein the pre-filter canister contains a fine depth filter and a felt filter.

A sanitizing filter for sanitizing a residential water filtering system has a water filter assembly including a cartridge operable for removable attachment to the water filter assembly. When the cartridge is attached to the water filter assembly, a water flow passes into the cartridge, mixes with sanitizing media within the cartridge, and passes back into the water filter assembly. The residential water filtering system is then filled and flushed repeatedly and the mixture of water and sanitizing media sanitizes the portions of the system that are downstream from the sanitizing filter.

The exchange unit includes a first flow path end portion having a first width; a main body portion having a second width larger than the first width; a second flow path end portion positioned on a side opposite to the first flow path end portion; and a slide extension portion including a portion larger than the first width and is configured to cover the first flow path end portion on an outer side of the first flow path end portion, and a portion larger than the second width and is configured to cover the main body portion on an outer side of the main body portion. The exchange unit is removably mounted to an existing pipeline with a distance between an upstream-side end portion of a pipeline and a downstream-side end portion of the pipeline being invariable only by a translational operation without using a rotating operation.

A screen panel assembly includes a screen panel and a raised screen component disposed thereon. The raised screen component includes an inclined screen surface that defines a first plane oriented at a first angle relative to the screen panel and a wedge surface positioned at a back side of the raised screen component. The inclined screen surface has a front edge that is aligned with a top surface of the screen panel and is substantially perpendicular to a longitudinal axis of the screen panel, the first plane being substantially perpendicular to a displacement vector along which the screen panel assembly is accelerated by a vibratory separation device. The wedge surface is adapted to disrupt a flow path of a flow of a material mixture flowing in a longitudinal direction across the screen panel by redirecting the flow around opposing sides of the raised screen component.

A screen panel assembly includes a screen panel and one or more raised screen components, wherein at least one of the raised screen components is disposed on the screen panel. Furthermore, each of the one or more raised screen components includes at least one inclined screen surface that defines a first plane that is oriented at a first angle relative to said screen panel. Additionally, the first plane is substantially aligned with a second plane that is oriented at a second angle relative to a third plane that is perpendicular to a displacement vector along which the screen panel assembly is accelerated by a vibratory separation device.

A water quality purification assembly includes a first water port, a second water port, an inner housing, an outer housing, a water filtering unit, and a flow guide member. The water filtering unit is provided in the inner housing; the flow guide member is provided between an outer wall surface of the inner housing and an inner wall surface of the outer housing. A first flow guide channel is defined between the inner housing and the outer housing; the first water port, the first flow guide channel, the inner housing, and the second water port are sequentially communicated. The first flow guide channel guides water in an extending direction of the first flow guide channel; and one of the first water port and the second water port is a water inlet, and the other of the first water port and the second water port is a water outlet.

A fuel filter includes a housing including a filter case and a filter element. The filter element includes a first filter including a first filtration section formed in a tubular shape by folding a sheet-like filtration member into pleats, a second filter disposed on an inner side of the first filtration section, and a first plate at which the first filter and the second filter are disposed. The second filter includes a second filtration section formed in a tubular shape by connecting both ends of a mesh-patterned thin plate, a first end portion covering a first end of the second filtration section, and a second end portion covering a second end of the second filtration section, the second end being on a side opposite to the first end. The first plate is disposed in the head and has a first through-hole formed at a center thereof.

A filter media, filter element, filter system and methods are provided. The filter media provides improved filter characteristics including water separation efficiency. The filter media may include one or more of increased surface roughness and/or embossments. The filter media may be provided by pleated filter media.

A fluid delivery system includes a settlement filter that is disposed within a primary fluid passageway and is configured to receive a portion of fluid that passes through the primary fluid passageway. The settlement filter includes a secondary filter fluid passageway having an inlet end that intersects the primary fluid passageway and a blind end opposed to the inlet end. At the intersection of filter fluid passageway with the primary fluid passageway, fluid conditions result in formation of a settlement area in the filter fluid passageway entrance. The filter fluid passageway includes a particle trap in the settlement area that collects particles that settle out of the fluid.
