An interface seal assembly for sealing a tubular filter element relative to a first component and a second component of a fluid filtration system. The interface seal assembly comprises an body located between the first and second components, and having: an aperture extending through the body for communicating with an internal cavity of the filter element; a first mounting surface comprising a first seal groove; and a second mounting surface opposite the first mounting surface, comprising a second seal groove. One of the first and second seal grooves has a circular shape, and the other has a non-circular shape. A first seal is located in the first seal groove, for sealing the interface body relative to one of the first and second components. A second seal is located in the second seal groove, for sealing the body relative to the other of the first and second components.

In this infiltration intake system, a structural body integrally includes a waster discharge direction control portion controlling a discharge direction for wastewater discharged from a filter toward a raw water side at a backwash time with a backwash mechanism portion in a prescribed wastewater discharge direction.

Provided is a filter apparatus, comprising two or more filter cartridges having a first end with an inlet and screen and a second end with an outlet and screen, and walls to contain a filter media held in a housing for holding the two or more filter cartridges in about the same orientation, and an attachment clamp connected to the housing. Also provided is a housing for holding two or more filter cartridges in about the same orientation and a method of using the filter apparatus and housing.

The present invention provides a portable high throughput liquid filter system.

Provided is a filter apparatus, comprising two or more filter cartridges having a first end with an inlet and screen and a second end with an outlet and screen, and walls to contain a filter media held in a housing for holding the two or more filter cartridges in about the same orientation, and an attachment clamp connected to the housing. Also provided is a housing for holding two or more filter cartridges in about the same orientation and a method of using the filter apparatus and housing.

A system includes a sand filter disposed within a tank. A pipe connected to the tank is configured to flow fluid in or out of the tank. The system includes a valve configured to selectively allow fluid to flow through the pipe and a flowmeter configured to measure a flow rate of fluid through the pipe. An automatic control unit includes one or more processors and a non-transitory computer readable medium storing instructions executable by the one or more processors to perform operations including determining a debris accumulation status for the sand filter based in part on flow measurements from the flowmeter, and determining a failure status of the valve based in part on flow measurements from the flowmeter.

The present disclosure is directed to fluid filtering systems and methods for use during semiconductor processing. One or more embodiments are directed to fluid filtering systems and methods for filtering ions and particles from a fluid as the fluid is being provided to a semiconductor wafer processing tool, such as to a semiconductor wafer cleaning tool.

A device and method for increasing the area available for passing contaminated stormwater through a granular media. The device comprises of one or more elements of predetermined size and shape. The increased area available for flow is obtained by introducing a first media into predetermined areas of the device, introducing a second media into predetermined areas of the device, and bringing into contact the first and second media.

A filtration device comprising a media basket, a baseplate, and a canister. The media basket is affixed to the baseplate. The canister has a cavity therein and is detachably coupled with the baseplate to enclose the media basket. The media basket contains a porous filtration material that efficiently removes contaminants from liquid. The device is configured to establish a first siphon to convey liquid from outside the device into the canister cavity through a canister pipe when a liquid level outside the filtration device is higher than the top of the weir in the canister pipe and configured to establish a second siphon to convey liquid from canister cavity through the top of a center riser pipe and out an outlet pipe when the first siphon has been established and the liquid level outside the filtration device is higher than the top of the center riser pipe.

In this infiltration intake system, a structural body integrally includes a waster discharge direction control portion controlling a discharge direction for wastewater discharged from a filter toward a raw water side at a backwash time with a backwash mechanism portion in a prescribed wastewater discharge direction.
