A fluid filter element for use with a filter housing having a selectably blockable outlet channel for unfiltered fluid, the filter fluid element including first and second end caps, a filter medium joined to the first and second end caps and defining a cylindrical configuration arranged about a central bore extending between the first and second end caps, a water separator operative to separate water from filtered fluid, a water collector arranged for collecting water separated from the filter fluid and a plug mounted on the second end cap and separate from the water collector and being configured for selective blocking of the selectably blockable outlet channel, when the fluid filter element is mounted in the filter housing in an operative orientation.

Systems and methods for disposing of blackwater are disclosed. A first vessel contains a screw running through the vessel from a first end to a second end. The screw is surrounded radially by a filter. The first vessel has a blackwater inlet adjacent the first end. An extrusion plate is adjacent the second end of the first vessel. A combustor vessel is configured to receive a solids component from the extrusion plate. A blackwater stream, consisting of a liquid component and the solids component, is passed through the blackwater inlet into the first vessel, is conveyed by the screw from the first end to the second end, and is pressurized against the extrusion plate. The liquid component is thereby forced from the blackwater stream through the filter and the solids component is forced through the extrusion plate into the combustor. The combustor is configured to combust the solids component.

A filter device, comprising a filter housing (1) having a fluid inlet (8) for unfiltered matter and having a fluid outlet (9) for filtrate and having at least one one-piece or multi-part filter insert (05, 17) held in the filter housing (1), which filter insert (15, 17) can be cleaned using a backwash device (25) having at least one backwash element (31) in counter flow to the direction of filtration, which backwash element can be moved along the inside of the relevant filter insert (15, 17) by means of a fluid-conveying drive shaft (29) of a rotary drive (69, 71), wherein the individual backwash element (31) has, at the end adjacent to this inside, at least one gap-shaped passage opening, which extends in parallel to the axis of rotation of the drive shaft (29) and which opens into a flow chamber connected to the drive shaft (29) in a fluid-conveying manner, is characterized in that at least one further backwash device (27) having at least one further backwash element (31) is present, in that the fluid-conveying drive shaft (29) is divided into chambers (73, 75) separated from each other, and in that in each case one backwash element (31) of one backwash device (25) is connected to one of the chambers (73, 75) and the other backwash element (31) of the other backwash device (27) is connected to another chamber (73, 75).

A filtration assembly includes a housing. The housing includes a first housing for fluid and a second housing opening for fluid. A containment cover is removably coupled to the housing. The containment cover defines a cover opening, a cover surface, and a flow passage. The cover opening is in fluid communication with the housing. The cover surface is substantially continuous around a circumference of the containment cover. The cover surface includes an open portion in fluid communication with the second housing opening. The flow passage is formed by a first passage surface and a second passage surface. The flow passage includes a first end in fluid communication with the cover opening. A second end is in fluid communication with the second housing opening through the open portion of the cover surface. The flow passage extends radially outward from the cover opening.

A high pressure filter assembly with minimal pressure drop includes a filter assembly with a cylindrical filter element housing having a central inlet at one end and an angled peripheral outlet on an opposite end, and an inside-out flow filter element coupled to the inlet having a lower endcap and an upper endcap assembly and filter media extending between the upper endcap assembly and the lower endcap, and wherein the upper endcap assembly includes an upper end cap and a diverter plate coupled to and spaced from an upper endcap of the upper end cap assembly with at least one vertical strut, wherein the diverter plate is angled in the direction of the angled peripheral outlet in a centerline plane of the peripheral outlet.

A fuel filter assembly includes a filter bowl body including a bottom wall, the bottom wall having a concave feature. The fuel filter assembly includes an electro-static discharge (ESD) pin at least partially positioned within in the concave feature. A method for discharging electro-static in a fuel filter assembly includes providing a filter bowl body including a bottom wall, the bottom wall having a concave feature. The method includes discharging electro-static by positioning an ESD pin at least partially within the concave feature.

A filter assembly includes a filter housing, a filter housing lid, a filter cartridge, an endplate, and a seal member. The filter housing defines a first cavity and comprises a return passage in fluid communication with the first cavity. The filter housing lid is selectively coupled to the filter housing and defines a second cavity coextensive with the first cavity. The filter cartridge is positioned within the first cavity. The endplate is coupled to a first end of the filter cartridge. The endplate is configured to interface with the filter housing. The seal member is coupled to the endplate and is configured to be received in the return passage. The endplate is configured to partially separate the filter housing from the filter cartridge.

An automated organic closed-loop grow enclosure that has rows of hydration trays that support removable (three across) grow containers for microgreens such as broccoli. Each grow container has a layer of soil. The seeds are treated with mycorrhizae and mixed with enriched top soil having a wicking agent. The grow containers are automatically watered once a day from the bottom and the capillary action of the soil lifts and holds the water in the grow container. LED Lighting is used to stimulate day and night cycles. The water is treated with magnets, turbulence and charcoal filters. The water cascades down the tiered trays using siphons. No other treatment of the water is necessary since almost no micro-organisms or organic material leak from the grow containers due to a filter barrier in the bottom of the grow container. Spectacular consistent growth rates are easily achieved.

The present disclosure relates to a fuel filter (1) for filtering diesel fuel supplied to an internal combustion engine (2). The fuel filter (1) includes a filter element (12, 19) for trapping and decomposing precipitates suspended in the diesel fuel. An solid acid catalyst like a zeolite is provided for decomposing precipitates trapped by the filter element (12, 19). Sterol glycosides (precipitates) are splitted into sterol and glycoside moieties, which are soluble in the biodiesel, thus preventing clogging of the filter by sterol glycoside agglomerates. The sterol and glycoside moieties pass to the engine where they are burnt. The present disclosure also relates to a method of filtering diesel fuel for supply to an internal combustion engine (2).

A skimmer basket assembly has an basket, a circular platform with a magnetically permeable ring supported on a spring, a guide tube having a lowermost end of the guide tube positioned above an uppermost position of the circular platform, and a flag assembly within the guide tube, the flag assembly having a central stem, a flag at an uppermost end, a magnetic tip at a lowermost end, and a float. With the skimmer basket in a housing, with water flowing through, and the circular platform at an uppermost position, the flag assembly is held to the ring, and, with debris collected in the basket, increased force compresses the spring, separating the flag assembly, allowing the flag mechanism to float upward as an alert that there is debris in the skimmer basket.
