A system for further filtering a liquid extract material after an initial extraction process. In an embodiment, the system includes a semi-rigid filter cup that is substantially cylindrical, the filter cup having a top and a bottom, wherein the top is oriented to receive filter media prior to a filtration process, and material to be filtered during the filtration process. The filter cup includes an integrated deformable flange at the top of the filter cup, an integrated top o-ring that is integrated into the top of the integrated deformable flange and an integrated bottom o-ring that is integrated into the bottom of the integrated deformable flange.

Modular fluid processing apparatuses, modular components and related methods are provided. A fluid processing apparatus for use in fluid processing systems can include a housing comprising first body half and a second body halves that are secured together. The first body half has one or more half bores that extend along a length of the first body half and the second body half has one or more half bores that extend along a length of the second body half with the one or more half bores in the first body half aligning with the one or more half bores in the second body half forming one or more full sleeve-receiving bores. The fluid processing apparatus can include one or more sleeves that are securable between the first and second body halves within the one or more sleeve-receiving bores to form piston pathways within the housing for receiving pistons.

A water-treating ceramic filter unit comprising a filter having pluralities of flow paths partitioned by porous ceramic cell walls and plugs alternately sealing the one-side or other-side ends of the flow paths; a housing containing the filter such that water to be treated is supplied from one end of the filter, and that the treated water is discharged from the other end of the filter; and seal members disposed on the outer edge portions of both end surfaces of the filter for longitudinally sandwiching and fixing the filter to the housing; the maximum of a gap between a side surface of the filter and the housing being equal to or less than the equivalent diameter of the flow paths.

The disclosure pertains to a spin-on fluid treatment device, including a treatment medium disposed within a housing, a top surface having an internally threaded bore and an outlet tube at least partially disposed inside said threaded bore in a concentric position. The outlet tube can have an externally oriented sealing portion for engaging with a complementary element of an inlet spud of an entity that receives said treated fluids. The outlet tube can be configured as an alignment feature to guide the treatment device onto the inlet spud during installation. The outlet tube can be configured with both an externally oriented sealing portion and an alignment feature. The disclosure also pertains to a system comprising a machine having a treatment device head and a spin-on fluid treatment device, a kit, a spin-on fluid filter cartridge, and a method of mounting a spin-on filter cartridge onto a filter head.

Embodiments for a fuel filter are provided. In one example, a diesel fuel filter comprises a header having an inlet port, an outlet port, a recirculation inlet port, and a recirculation outlet port; and a filter body made having different material than the header, the filter body coupled with the header and housing a filter membrane. In this way, electrostatic discharge may be reduced.

A grease trap or solids collector for separating waste from waste water has a tank having a multilayer outer wall made of an outer layer of un-foamed plastic, an intermediate layer of foamed plastic, and an inner layer of unfoamed plastic; an inlet invert in the tank for receiving incoming waste water; and an outlet invert for removing water from the tank. An extension collar made up of segments can be included.

A rotary pressure filter, comprising a filter drum and a housing. A sensor is attached to the housing and emits light through a light-permeable section of the housing in the direction of a filter cake. The sensor receives light reflected from the filter cake through the light-permeable section of the housing. A processing unit compares properties of the emitted light with those of the received light and determines an absolute thickness of the filter cake and/or a change in the thickness of the filter cake over a pre-determined time. The invention further relates to a corresponding method.
