A water separation group is for a fuel filtration and separation assembly of a vehicle fuel circulation system. The assembly extends along a longitudinal axis positionable in the vehicle in a horizontal position having a filtration group. The water separation assembly is associable to the filtration group for receiving filtered fuel, being positioned in series along the longitudinal axis. The water separation assembly has a main body defining a separation chamber and at an axial end, an outlet wall with an outlet mouth. A separator is accommodated in the separation chamber. A blocking device is below the separator to prevent the return of water to the separator. The blocking device has a blocking surface extending longitudinally forming an angle that inclines at least a portion of the blocking surface to allow water separated from the fuel to flow towards the outlet wall from which the blocking surface extends.

A filter cartridge for a fuel circulation circuit of a vehicle.

The filter cartridge comprises a cartridge body identifying a filtration chamber. In said filtration chamber, the filter cartridge further comprises at least one filter insert which divides said filtration chamber into a dirty chamber containing fuel to be filtered and a clean chamber containing filtered fuel.

The filter cartridge further comprises a ventilation device suitable to ventilate in the dirty chamber, wherein the ventilation device comprises at least one ventilation duct placed in an upper area of the filtration chamber in which the air floating in the fuel accumulates. Said ventilation duct has a plurality of ventilation holes mutually spaced from one another through which the air is removed from the filtration chamber.

A rotary vacuum filter for separation of bisphenol A-phenol adduct crystals from a crystallization liquor is provided. The rotary vacuum filter includes a filter drum with a perforated sector on a lateral surface of the filter drum; a non-polymeric filter cloth attached to the filter drum and covering said perforated sector; and a vacuum pump in fluid communication with an interior surface of the perforated sector. Methods and uses of thereof are also provided.

A filter apparatus positionable outside a washing machine and connectable to a drain device of the washing machine, the filter apparatus including a filter case including a case inlet a case outlet; a filter detachably installable inside the filter case, the filter through which water flowing from the case inlet to the case outlet passes; a sensor to detect water entered into the filter apparatus from the drain device and to produce a corresponding signal; and a filter cleaning device to clean the filter in accordance with the signal produced by the sensor.

A filter apparatus is for use with a hydraulic machine. The filter apparatus includes a connecting part and a filter cartridge. The connecting part includes a sealing face, which is configured for sealing abutment on the hydraulic machine. An input connector and an output connector are arranged within the sealing face. The filter apparatus further includes a separate retaining part on which the filter cartridge is fixedly received. The connecting part has a pivoting appendage extending along a pivot axis on a side of the connecting part facing away from the sealing face. The retaining part is fluid-tightly adapted to the pivoting appendage such that (i) its pivoting position with respect to the pivot axis is continuously adjustable relative to the connecting part, and (ii) between the retaining part and the pivoting appendage, a first and a second pressure chamber are arranged.

A filter sector assembly for a disc filter, which disc filter has a fiber suspension containing bath and a core assembly adapted to rotate on a horizontal axis. The filter sector assemblies are rotatably supported with relation to the bath on the core assembly. The filter sector assemblies are spaced along the core assembly and supported on the core assembly. Each filter sector assembly (50) has two adjacent filter sectors (10A; 10B) releasably fixed to a bent support plate (30). The two adjacent filter sectors (10A; 10B) are attached as a pair of filter sectors (10A; 10B) by fastening the support plate (30) to the core assembly (21; 21A, 21B) of the disc filter.

The present invention provides a multi plate screw press sludge dewatering machine and a helical shaft thereof. The multi plate screw press sludge dewatering machine includes fixed rings, movable rings, the helical shaft, a sludge inlet tank and a sludge discharging tank; the helical shaft adopts a variable diameter variable pitch helical shaft, a lead angle arrangement sequence of a helical blade of the whole helical shaft is gradual reduction from the sludge discharging tank to the sludge inlet tank, and the lead angle arrangement sequence is gradually reduced from 16-22 to 6-14; a pitch of the helical shaft is gradually increased along a direction from the sludge inlet tank to the sludge discharging tank; a diameter of a shaft body of the helical shaft is gradually increased along with a direction of the sludge discharging tank from a position of a shaft length; and blockage prevention plates are arranged on two sides of the bottom of the helical blade. The helical shaft in the present invention is specially designed, so that the pitch is more reasonable, a helical angle is gentler, frictional resistance when sludge passes through the helical shaft may be effectively reduced, and phenomena of shaft blockage and shaft sticking of the sludge may be reduced.

A filter device comprises a first filter mechanism and a second filter mechanism, the first filter mechanism is connected to the second filter mechanism, wherein the first filter is configured to filter disinfectants, impurities, and organic matters in water, and the second filter is configured to filter germs in the water. A faucet water purifier comprises above filter device.

The invention relates to a filter panel (1) for a drum filter (2) which is used for filtering off solid particles from a liquid. The filter panel (1) comprises a first side (3) being adapted to be attached to a drum (4) of said drum filter (2), a second side (5) being adapted to receive a filter cloth (6), and a plurality of through holes (7) extending from said first side (3) to said second side (5), each hole (7) defining one or more side walls (8). The filter panel (1) is characterized in that at least one of said holes (7) comprises an inclined side wall (8). The invention also relates to a drum filter (2) for filtering liquid.

A filter for a non-plumbed appliance is provided. The filter includes a filter housing having a sidewall extending along a longitudinal direction between a first end wall and a second end wall. A flow distribution channel is also defined by the sidewall of the filter housing, the flow distribution channel extending outwardly from the sidewall along the radial direction and along the longitudinal direction between the flow aperture and the first end wall of the filter housing. The flow distribution channel equalizes the pressure gradient on the outer surface of the filter media, resulting in an improved flow pattern, increased clogging resistance, and improved filter performance capacity.
