A regenerative filter that includes a filter housing having inlet and outlet zones; a fluid path provided between the inlet and outlet zones; a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path; and a tube sheet that is supported across the filter housing, that is disposed just before the outlet zone and that provides the support for the plurality of filter elements. The plurality of filter elements are disposed in an array and includes bridging members or elements that connect between adjacent filter elements, and that forms with the filter elements, a closed interstitial space between adjacent filter elements for liquid flow; a nanoscale barrier on interior surfaces, including that of the regenerative media itself, providing a mechanism to disrupt the cell wall of microscopic viruses and organisms.

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 fuel filter device includes a bag-shaped filter member filtering fuel that is drawn into a fuel pump, an inner frame member retaining the filter member in an expanded state, and a mounting member connected to the inner frame member and serving to communicate an internal space of the filter member with an outside. A valve chamber is defined by the inner frame member and the mounting member, and a check valve serving to prevent backflow of fuel is disposed in the valve chamber. The check valve includes a flat-plate shaped valve body having elasticity. The check valve opens against its weight when the fuel pump is operated, and the check valve closes due to its weight when the operation of the fuel pump is stopped.

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. More specifically, and without limitation, the present disclosure relates to a single serve pod apparatus, process of assembling and methods of use of the apparatus.

A method for pre-wetting a polypropylene (PP) filter for filtering slurry and a PP filter package are provided. The method for pre-wetting the PP filter for filter slurry consists of steps of: pre-wetting a PP filtering media of the PP filter and packaging the pre-wetted PP filter in a packaging member sealingly. A PP filter package includes a cartridge, a PP filtering media and a packaging member. The PP filtering media is disposed in the cartridge to form a PP filter. The PP filtering media is pre-wetted, and the PP filter is sealingly packaged in the packaging member.

A filter press includes a frame, a hydraulic system for compressing and releasing filter plates, the filter plates, a filter chamber, a feed pump, a high-pressure clean water pump, a control system, a rotating plate, a cake removal knife, a squeeze disc, a squeeze disc sleeve, a drive shaft, a brake, a left pull rod, a right pull rod, a pull rod disc, a connector and clutches. The filter cake in the entire filter press can be removed without opening the filter plates in sequence. The filter cake washing is carried out in an enclosed room in a normal direction and a reverse direction, which can not only maintain the dryness and cleanness of the working environment, but also can effectively collect, process treat and recycle the washing water, thus achieving the zero discharge of waste water to meet the environmental requirements at a low cost.

A dishwashing appliance with a shrouded filtration assembly for removing dishwashing sediment from recirculated dishwashing fluid is provided. The dishwashing appliance may include a tub, a spray system, a recirculation pump, a drainage pump, and a shrouded filtration assembly in fluid communication with the spray system, the recirculation pump, and the drainage pump. The shrouded filtration assembly may include a lid, a filter frame, and a sump housing.

A water providing station having a housing that supports a basin. A water dispensing mechanism is associated with the basin and is coupled to a water supply line located within the housing. A filter is also coupled to the water supply line. Mounted to a portion of the housing is a door that is moveable between open and closed positions. The filter is mounted to and supported by the door for movement moved with the door between the open and closed positions.

A replaceable water filter includes a filter assembly having a filter structure with first, second, and third filtering elements sharing a common axis, the first filtering element for removing and/or reducing particulate contaminants in the water, the second filtering element for removing and/or reducing particulate and organic contaminants in the water and the third filtering element for removing and/or reducing at least one of fluoride and arsenic in the water. The filter further includes a housing that contains the filter assembly. The housing includes a first end adapted to removably attach the filter to a filter mount of the refrigerator where the filter communicates with the water supply of the refrigerator. The first filtering element can be fabric, the second filtering element can be a carbon block, and the third filtering element can be activated alumina.

A flat filter for water treatment is provided. The flat filter for water treatment according to one embodiment of the present invention comprises: filtration members formed in the shape of a plate having a predetermined area; support frames, which are coupled to the rim sides of the filtration members so as to support the filtration members, and have channels into/in which filtered water produced through the filtration members flows and moves; and gap adjustment members coupled to the support frames so as to adjust the gap between the filtration members adjacent to one another.
