Disclosed is a double-water-output cylindrical integrated water purifier. A clean water flow channel, a pure water branch flow channel and a waste water bypass flow channel are further provided in the base, and a clean water outlet in communication with the clean water flow channel is provided at a side of the base; the pure water flow channel is communicated with the clean water flow channel via the pure water branch flow channel, and a second check valve for controlling water to flow into the clean water flow channel unidirectionally is disposed in the pure water branch flow channel; the waste water outlet end face is further communicated with the clean water flow channel via the waste water bypass flow channel, and a third check valve for controlling water to flow into the clean water flow channel unidirectionally is disposed in the waste water bypass flow channel.

Disclosed is a filter device having a filter housing (10) that comprises at least two ports (12, 14), such as an inlet for unfiltered matter and an outlet for filtrate, and accommodates a replaceable filter element (16), which is characterized in that by a shut-off device (18) a fluid-conveying connection between the inlet (12) and the outlet (14) that exists in an open position, is blocked in a blocking position, and in that by an actuation device (20) the shut-off device (18) can be brought into these individual positions.

A filtration system comprises a housing and a shell housing removably coupled to the housing. A valve comprise a valve housing and a plunger. The plunger comprises a seal member structured to seal an opening in the valve housing. The plunger is axially movable between a closed position, in which the seal member seals the opening, and an open position, in which the seal member does not seal the opening, thereby permitting fluid to flow through the valve housing. A filter element comprises filter media and an endcap. The endcap comprises an alignment tab configured to rotationally secure the filter element with respect to the shell housing when the shell housing is received in the housing. The endcap comprise a valve interaction projection structured to transfer rotation of the filter element and the shell housing to the plunger during installation of the filter element.

A water drain assembly for draining water from a filter assembly comprises a conduit, a water canister, and a venturi. The conduit fluidly connects a bottom portion of the filter assembly to a bottom portion of the water canister. The venturi comprises a first venturi inlet that allows fluid to flow from the fuel tank and into the venturi, a second venturi inlet that allows fluid to flow from the water canister and into the venturi, and a venturi outlet that allows fluid to flow from the venturi and into the filter assembly. The second venturi may comprise a capillary.

A fuel filter element has a screen fabric as a filter medium and a support tube supporting the screen fabric. A valve body guide for guiding a spherical valve body is provided. The valve body guide has a fluid channel and one or more support ribs for supporting the spherical valve body. The support ribs extend along a longitudinal direction of the fluid channel and project radially into the fluid channel. A filter assembly with such a fuel filter element is provided. The filter assembly has a ball valve with spherical valve body and a filter housing with a valve seat for the spherical valve body of the ball valve.

A liquid filtration system comprising a filtration tank with: a separating roof on which are mounted groups of hoses fixed to respective support plates; a fluid distributor plate comprising a central portion without perforations, and a peripheral portion with a plurality of perforations, said distributor plate being located between the hoses and a lower inlet duct for the water to be filtered comprising an upper opening for supplying liquid to the holes near the central portion of the distributor plate and a lower opening for supplying liquid to the holes of the peripheral portion which are furthest from the central portion. The filter comprises a filter material, an outlet duct for the filtered water at the upper area of the tank, a regeneration circuit of the filter medium; a filter self-cleaning circuit and a control panel.

A method and apparatus for monitoring a water pressure in a filter tank are disclosed. The apparatus may include a pressure sensor disposed within a housing and configured to monitor the water pressure in the filter tank. The apparatus may also include a controller disposed within the housing, the controller communicatively connected to the pressure sensor and the controller configured to receive a sensor signal from the pressure sensor, and to determine the water pressure in the filter tank based on the sensor.

An upper plate provided on upper ends of a filtration member and an inner tube includes a tubular portion along the inner tube, a rib formed so as to protrude inward in a radial direction from an inner circumference of the tubular portion, and a hole formed in the rib. A gripping member has a protrusion portion that protrudes downward from a body portion having a thick plate shape inserted into a hollow portion of the tubular portion. When the gripping member is mounted on the upper plate, the protrusion portion is inserted into the hole.

The invention relates to a device for separating solid materials out of liquids or gases and for discharging solid material. The device comprises a pressurised container and at least one filter element, the at least one filter element being arranged in a flexible container which is arranged in the pressurised container and is sealed tightly relative thereto. The pressurised container comprises at least one outlet for discharging the solid material and the flexible container comprises at least one discharge connection, the discharge connection of the flexible container being guided through the outlet of the pressurised container and sealed tightly relative to the pressurised container. In this case the outlet and the discharge connection of the flexible container can be closed and sealed by means of a closure mechanism relative to the environment outside the flexible container and the pressurised container.

A side-flushing mechanical filter system includes a spring positioned within a pipe and a plurality of plates attached to the spring, each plate defining at least one hole, and a rod positioned partially within the pipe, a proximal end of the rod attached to a distal-most plate and a distal portion of rod extending from the distal end of the pipe. A major face of each plate is configured to arrest sediment from water flowing into the pipe via a first water inlet while the holes defined by the plates enable filtered water to flow therethrough and out of the first water outlet when the first water inlet and first water outlet are opened. During cleaning of sediment, graywater flows into the pipe via the second water inlet and over the plates while a user moves the rod to dislodge sediment from the plates and toward an outlet.
