A valve-sensor assembly for a filter assembly that filters water from a fluid. The valve-sensor assembly includes a sensor body and a drain valve body. The sensor body includes a filter element engagement portion having a hollow interior that extends longitudinally through a length of the sensor body and a protrusion that extends circumferentially along an exterior surface of the filter element engagement portion. The sensor body further includes one or more water-in-fluid sensors provided at the exterior surface of the filter element engagement portion. The drain valve body includes a main body having a drain port, and a valve extending from the main body and extending at least partially within the hollow interior. The valve has an interior passage in fluid communication with the drain port.

Structures for housing a filtration media for the removal and/or solidifying of synthetic ester-based fluids from liquids are provided. The structures disclosed include: a stormwater insert container for installation within a storm drain designed for intake of high volumes of water; an angling filter plug mounting structure and pre-filter basket for a flush installation on a planar floor, such that the filtration media rests beneath the floor and releases filtered liquids into a drainage area; a trench filtration assembly for installation into a trench below surface level, such that the unfiltered liquid passes through the trench and a trench box disposed within the trench filtration assembly prior to passing through the filtration media into a drainage area; and a liner box assembly for installation over an opening made in a non-permeable liner for purposes of pre-filtering contaminated liquids as it flows through the liner box and subsequently the filtration media.

A liquid treatment cartridge includes a housing, the housing including a housing part forming an axial end of the housing and including a connecting head at the axial end of the housing. The connecting head includes at least three liquid ports, each at an end of a respective channel defined by the housing part. The connecting head is configured for insertion into a head part of a liquid treatment system such that the liquid ports of the connecting head are in sealed liquid communication with respective liquid ports in the head part. The liquid treatment cartridge includes at least one separate flow conductor part on the inside of the housing, attached to the housing part and including at least one conduit for conducting liquid so as to separate interior ends of at least two of the channels from those of at least one other of the channels.

A fluid degassing device includes a first housing, a second housing disposed within the first housing, a first flow circuit defined by the second housing and the first housing between a first flow circuit opening and a second flow circuit opening of the first flow circuit, and a tube bundle of selectively permeable membrane tubes disposed in the first flow circuit between the second housing and first housing. The tube bundle is disposed at least partially around a circumference of the second housing and the first flow circuit is defined between the first flow circuit opening of the first flow circuit and the second flow circuit opening such that fuel flows rotationally around the second housing through the tube bundle.

A water purification system for an ornamental aquarium is easily assembled as either a canister or a hang-on-back type model with a water tank or aquarium without compromising with an aesthetic appearance and low noise. The filtration element includes filtration blocks connectible in series for function and can be disassembled into a plurality of blocks that are reassembled to form the canister model and the hang-on-back model with a secure positioning feature.

The invention relates to a filter element assembly for filtering a fluid, optionally including water separation. A filter element has at least one annular filter bellows which is flowed through in the radial direction, and at least one end plate arranged on the filter bellows on the end side. At least one circumferential sealing element is arranged on the end plate. The sealing element seals the clean side from the raw side of the filter element. The sealing element is compressed between a first housing part and a second housing part of the filter system, sealing a housing interior from the environment. The invention also relates to a filter system having the filter element assembly with the sealing element.

An embodiment an apparatus, including: a housing that permits airflow there-through; an air permeable filter disposed in the housing; where the air permeable filter is angled such that it does not sit in a horizontal plane across the housing; and an attachment mechanism for securing the housing to an enclosure that houses heat generating electronics. Other embodiments are described and claimed.

A valve-sensor assembly for a filter assembly that filters water from a fluid. The valve-sensor assembly includes a sensor body and a drain valve body. The sensor body includes a filter element engagement portion having a hollow interior that extends longitudinally through a length of the sensor body and a protrusion that extends circumferentially along an exterior surface of the filter element engagement portion. The sensor body further includes one or more water-in-fluid sensors provided at the exterior surface of the filter element engagement portion. The drain valve body includes a main body having a drain port, and a valve extending from the main body and extending at least partially within the hollow interior. The valve has an interior passage in fluid communication with the drain port.

A modular filtration platform having at least one manifold head and at least one respective filter cartridge assembly. Each manifold head is connected to one another to establish a water flow in a series or parallel manner. Each filter cartridge assembly is releasably secured from rotation relative to the manifold head by a locking mechanism. An aperture on the filter cartridge assembly annular collar mates with a protruding resilient extension on either the manifold head or support bracket. Alternatively, an aperture on the filter cartridge assembly annular collar and an aperture on the manifold head annular collar mate with a protruding member from a locking ring extending through both apertures. An integrated sensor package may be integrated with the system for true managed water visible/audible indications and Wi-Fi interface to facilitate virtually instantaneous response times for filtration needs.

A water filtration system includes at least one filter cartridge, a seat body and a flow guide adapter. The seat body has a connecting portion defining two passages respectively connected downward to water inlet and outlet of the filter cartridge. The seat body further has a main passageway that has two apertures in communication with the passages of the connecting portion. The flow guide adapter is inserted in an entrance of the main passageway of the seat body, and has a tube fitting portion, a flow guiding portion integrally extending from the tube fitting portion, and an interior tunnel extending through the tube fitting portion to the flow guiding portion for receiving water flow from a conduit. In particular, the flow guiding portion guides water flow from the interior tunnel to the filter cartridge and then back to the main passageway of the seat body.
