The present invention relates to a filter device for separating debris from a fluid. The filter device includes a housing having at least one inlet, at least one first outlet, and a second outlet. The filter device further includes a filter cartridge that allows fluid to pass therethrough but prevents passage of debris therethrough. The filter cartridge is positioned within the housing so as to define an upper chamber and a lower chamber within the housing. The at least one inlet is positioned so as to allow contaminated fluid to enter the lower chamber of the housing. Fluid must pass through the filter cartridge in an upward direction to reach the upper chamber, and the first outlet is positioned so as to allow filtered fluid to exit the upper chamber. The second outlet is positioned to allow debris accumulated within the lower chamber to be discharged.

The following summary of the invention refers to the development of a multiple filtering device composed of three filtering elements (01 to 03) that are concentrically mounted on the lid (09) in the sequence EF1 (01), EF2 (02) and EF3 (03) with mesh measurements of different microns, forming four filtering chambers, with the purpose of retaining solids from agricultural spraying mixtures, monitoring the restrictive framework of the filtering elements through pressure switches (69.2) and pressure transducers (77) and alerting the obstruction through audio visual signaling (83, 83) so that the operator knows the exact moment to clean the multiple filtering device.

A multi-stage filter for filtering and removing fluids includes (1) a filtering base, and (2) a fluid transfer cap. The filter base includes: (i) a cover; (ii) a second stage filter positioned inside the housing of the cover; and (iii) a first stage filter positioned inside the housing of the second stage filter. The fluid transfer cap attaches to the first end of the cover and includes: (i) a first closed end; (ii) a second end having an opening that is positioned opposite the first end; (iii) an annular skirt that extends between the first and second ends; (iv) an annular shaped barrier member positioned inside and spaced apart from the annular skirt; (v) a fluid inlet comprising an extension member that extends through a side of the annular skirt to the annular shaped barrier member; and (vi) a fluid outlet.

This disclosure generally relates to perforated filter media and coalescing filter elements utilizing perforated filter media. One example coalescing filter element is structured to separate a dispersed phase from a continuous phase of a mixture. The filter media includes a first coalescing layer. The first coalescing layer includes a first filter media. The first filter media has a plurality of pores and a first perforation. Each of the plurality of pores is smaller than the first perforation. The first perforation is formed in the first filter media and extends through the first filter media. The plurality of pores are structured to capture a portion of the dispersed phase. The first perforation is structured to facilitate the transmission of coalesced drops of the dispersed phase through the first coalescing layer such that the coalesced drops of the dispersed phase are separated from the portion of the dispersed phase captured in the first coalescing layer.

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.

A filter assembly of a fluid filtration system includes a filter housing and a filter element. The filter housing includes an engagement member. The filter element includes a media pack and a sealing member. The media pack includes filter media that is configured to filter a fluid passing therethrough. The sealing member is coupled to the media pack and is engageable with the engagement member. The sealing member is formed in a Reuleaux shape.

A pool filter system includes a filter housing with an open interior. A pleated filter container in the open interior of the filter housing has a pleated filter side wall and divides the interior of the filter housing into an pleated filter compartment and an particulate filter compartment surrounding the pleated filter side wall. The pleated filter side wall has a plurality of pleated filter container openings. A particulate filter medium is within the particulate filter compartment, and a pleated filter is within the open interior of the pleated filter compartment. A water inlet communicates with the particulate filter compartment, and a water outlet communicates with the pleated filter compartment. The pleated filter container openings in the pleated filter container side wall have a dimension that is less than the diameter of the particulate filter medium. A backwash assembly and a method of filtering pool water is also disclosed.
