According to one aspect of the present disclosure, a filter assembly includes a filter housing including a housing inlet and a housing outlet, and a filtering section located downstream of the housing inlet and upstream of the housing outlet. The filtering section includes a first filtering portion, a second filtering portion, a wall longitudinally separating the first filtering portion and the second filtering portion, a filtering outlet, and a valve located in the filtering outlet. The valve includes a closed condition and an open condition, and wherein, in the valve closed condition the valve blocks flow from the second filtering portion to the housing outlet.

The invention relates to an apparatus (1, 1′) for filtering a fluid, in particular a Bernoulli filtering apparatus (1, 1′), comprising: a housing (3, 3′), a plurality of filter elements (55), arranged in the housing (3, 3′), for filtering the fluid, an inlet (5) for admitting fluid to be filtered into the housing (3, 3′), and an outlet (7) for discharging the filtered fluid from the housing (3, 3′). The invention solves the stated problem by providing the housing (3, 3′) with a plurality of housing segments (23) which can be connected to adjacent housing segments (23), and by a filter element (55) being arranged at least partially inside each housing segment (23), and by the housing segments (23) and filter elements (55) together forming a modularly assembled filter module (9). The invention also relates to apparatuses of the kind initially specified which further comprise: at least one housing cover (25) for closing the housing, at least one filter cleaning mechanism (11) for cleaning the filter element (55) of residues from the filtered fluid, and at least one backflushing system (13, 13′) in fluid communication with the filter element (55), for conducting and discharging the residues from the filtered fluid. The invention solves the stated problem by the filter cleaning mechanism (11) being associated with the housing cover (25) and in particular being fixed thereto, and by the backflushing system (13, 13′) being associated with the housing (3, 3′), in particular with housing segments (23).

Filters comprising at least one filter arm comprising a plurality of hollow elements in fluid communication with each other, the hollow elements having porous walls, the at least one filter arm having a first end and a second end; and, a hollow base having a side wall, and a base outlet port, wherein the hollow base is in fluid communication with the at least one filter arm, wherein the second end of the at least one filter arm is connected to the hollow base; filter devices including the filters, and methods of using the filters, are disclosed.

Filters comprising a filter arm comprising a plurality of hollow elements in fluid communication with each other, the hollow elements having porous walls, the filter arm having a first and a second end; a hollow transition element comprising a collector having a side wall, a central cavity, an upper closed end and a lower open end; and a hollow transition element arm having a first and a second transition arm end, and a porous side wall; wherein the first transition arm end is in fluid communication with the second end of the filter arm; and the second transition arm is connected to the side wall of the collector, and is in fluid communication with the central cavity of the collector; and, a hollow base having a side wall, and a base outlet port, wherein the hollow base connected to, and in fluid communication with, the collector; filter devices including the filters, and methods of filtration using the filters, are disclosed.

A filter cartridge with easier extraction provided by a roll-out clearance region for a radial seal is provided. The filter cartridge may be a two stage filter with the seal being located between stages and usable in a filtration vessel having a central separation wall with one or more riser pipes. Also, a new vessel is disclosed with multiple diameters for first and second stages of the housing with a larger second stage diameter as compared to the first stage, which can reduce door size and/or cause fluid flow velocities to be slower at the second stage relative to the first stage.

A pipeline filter assembly comprising a base assembly, an outer wall, and a lid assembly. The outer wall has a lower end portion and an upper end portion, wherein the upper end portion comprises a lower collar, and the lower collar comprises at least one lock notch spaced around an exterior surface thereof. The lid assembly is configured to couple to the lower collar of the outer wall. The lid assembly has an upper collar configured to threadedly mate with the lower collar. The upper collar has at least one housing that projects from the upper collar, the housing having an interior surface, and at least one biasing clip pivotally mounted within the housing for releasable engagement with the lock notch. A pair of pipeline filter assemblies, wherein at least one connection plate is used.

A connector assembly for fluid filter elements is provided comprising first and second connector elements each comprising at least two connector snap arches, each of the connector snap arches including a snap tooth lock; and at least two connector snap arms, each of the connector snap arms including a snap tooth; each connector element having a central opening, and an annular channel for receiving an end of a hollow cylindrical filter element; a gasket arranged between the first connector element and the second connector element, the gasket having a central opening; wherein the first connector element and the second connector element are lockably engageable with each other when placed in contact with each other and axial force is applied such that respective connector snap tooth is retained in each respective connector snap tooth.

A filter module for a filter assembly has a primary filter element and a secondary filter element. A water separation interface is provided for discharging water, which has been separated by the primary filter element from a fluid to be filtered, from the primary filter element. A primary filter interface is provided for discharging fluid, which has been filtered by the primary filter element, from the primary filter element. A secondary filter interface is provided for discharging the fluid, which has been filtered by the secondary filter element, from the secondary filter element. The water separation interface, the primary filter interface, and the secondary filter interface are arranged coaxially to a symmetry axis of the filter module. The water separation interface, the primary filter interface, and the secondary filter interface are each designed for outflow of material flows in axial direction of the symmetry axis.

A filter element for use with a filter assembly having a filter housing and a rotationally releasable locking mechanism, the filter element including first and second end plates, the second end plate having a central aperture, a filtering medium arranged between the first and second end plates in a generally hollow cylindrical configuration about a central bore arranged about an axis, the central bore communicating with the central aperture in the second end plate, at least one perforated cylindrical pipe located in the central bore and a locking mechanism rotating assembly, sealingly extending through the central aperture of the second end plate and having a seal mounted thereon, for sealing the filter element in the filter housing.
