A dewatering system for separating a slurry into solid material and effluent water. The dewatering system comprises a plurality of support frames arranged to enclose an interior space of the dewatering system, with the interior space being configured to receive the slurry. The dewatering system further includes geo-fabric material positioned on a portion of the support frames, with the geo-fabric material being configured to filter the slurry received within the interior space, such that effluent water permeates through the geo-fabric material and is discharged from the interior space. The dewatering system further comprises a dump door assembly associated with at least one of the support frames, with the dump door assembly including a plurality of hatches configured to selectively open to allow effluent water to be discharged from the interior space of the dewatering system.

A filter arrangement includes a first filter media construction having a burst disc arrangement that is triggerable to rupture and open a flow path through the media construction. The first filter media construction can be oriented within the interior volume of a second filter media construction.

A filter cartridge for a domestic cooling appliance includes a beaker-shaped housing which is provided at an open end with a coupling for securing to a filter head, and a particle filter insert which is received in the housing. The particle filter insert is guided movably along an axis of the housing between an abutment position, in which it is embedded completely in the housing, and a position in which it at least partially protrudes from the housing. A domestic refrigeration appliance having the filter cartridge is also provided.

A single serve pod system, a single serve pod assembly system, a single serve coffee system, a single serve coffee pod apparatus, a filter apparatus, a process of assembling a single serve reusable pod, and methods of use are presented in this disclosure. More specifically, and without limitation, the present disclosure relates to a single serve coffee preparation system for the preparation of a reusable coffee pod in accordance with brewing coffee, tea, and other brewing. More specifically, and without limitation, the present disclosure relates to a single serve pod assembly system and methods of use.

A flow cap may include an outer ring, an inner ring, an inlet portion, and an outlet portion. The inlet portion may include first portions of the outer and inner rings, and a plurality of arms extending between the first portions of the outer and inner rings, wherein the arms at least partially define an inlet aperture configured to provide flow communication between an inlet port of a filter base and an interior portion of a filter element. The outlet portion may include second portions of the outer and inner rings, and a plate including an outlet aperture providing flow communication between an outlet port of the filter base and an exterior portion of the filter element. The outlet portion may also include a wall, wherein the plate and the wall prevent flow communication between fluid entering the inlet portion and fluid entering the outlet portion.

A filter assembly includes a housing and a first filter, a second filter, and a heat exchanger all positioned in the housing. The filter assembly also includes a first inlet and a first outlet and defines a first liquid flow path. The first liquid flow path may extend within the housing between the first inlet and the first outlet through the first filter and along a first side of the heat exchanger. The filter assembly further includes a second inlet and a second outlet and defines a second liquid flow path. The second liquid flow path may extend within the housing between the second inlet and the second outlet through the second filter and along a second side of the heat exchanger.

A control mechanism for self-cleaning filtration systems. One embodiment is a controller for a filtration system that comprises a suction scanner and a screening element having modifiable respective locations therebetween. The controller comprises an input terminal for receiving a relative location signal and additional a differential pressure input terminal. The controller monitors differential pressure and outputs an activation signal after the differential pressure has exceeded a threshold value. The controller outputs a termination signal based on the relative location signal. Another embodiment is a filtration system that comprises: a screening element located within a filtration chamber, and a suction scanner for self-cleaning thereof. A location tracker communicates to a switching mechanism during self-cleaning sessions a signal indicative of a location of the suction scanner with respect to the screening element. The switching mechanism automatically terminates self-cleaning sessions based on the signal.

A filter cartridge 38 includes a first endcap 41 defining a first open aperture and having at least first and second protrusions extending from a wall along the aperture and into the first open aperture. The first protrusion is spaced from the second protrusion in both a vertical direction and a circumferential direction. The filter cartridge also includes filter media 44 and a second endcap 42 . The filter cartridge is mountable in a filter bowl 36 having an inner liner assembly, and the bowl and the inner liner assembly is connectable to a filter head to form a filter system. The filter system can have any one or combination of the following features: a filter lock-out mechanism to ensure that the filter head and the filter bowl are not connectable unless there is a proper filter cartridge installed therein; an automatic drain mechanism to drain the filter bowl of liquid before the filter cartridge is removed from the bowl; and a cartridge retention mechanism, to ensure that the filter cartridge remains with the filter bowl after the filter bowl has been removed from the filter head. Adaptor rings can be utilized in order to test other types of filter elements in the system, when those other types of filter elements do not have the protrusion arrangement. Assemblies, methods of servicing, methods of installing, methods of use, and methods of retaining can be practiced.
