A water filtration system is also disclosed. The water filtration system includes a regenerative media filter vessel, a filtrate line, a feed line, a recirculation line, a gas line, and at least one pump. A method of filtering water in a system comprising a regenerative media filter is disclosed. The method includes operating the system in a filtration mode, operating the system in a cleaning mode responsive to a differential pressure measurement across the regenerative media filter, operating the system in an aeration mode, operating the system in a pre-filtration mode after operating the system in the cleaning mode, operating the system in a drain mode, and operating the system in the filtration mode following the drain mode. A controller and non-transitory computer-readable medium having computer-readable signals stored thereon that define instructions that, as a result of being executed by the controller, instruct the controller to perform a method of operating a water filtration system are disclosed.

The invention relates to a candle filter device, primarily for filtration of solids from liquids, and containing one or more candle filter elements and the process of operating the same.

Aspects of the present disclosure relate to an apparatus for filtering a fluid. One exemplary aspect including a casing having an interior cavity and extending between a fluid inlet and a fluid outlet at opposed ends thereof, a tube sheet assembly spanning the interior cavity the tube sheet assembly having a plurality bores therethrough and a plurality of filter media tubes each extending from one of the plurality of bores in the tube sheet assembly. In some exemplary aspects, the tube sheet assembly may comprise a plurality of retaining plates sandwiched together with a tube sheet plate. In some exemplary aspects, the apparatus may further comprise at least one restrictor plate adapted to obstruct at least one of the plurality of bores of the tube sheet.

A backflow of liquid inside a filter device during an operation of an internal combustion engine is allowed to be obviated while air inside the filter device is purged so as not to generate bubbles in the liquid. An outflow portion that includes a cylindrical portion having a substantially bottomed cylindrical shape and a back pressure valve provided inside the cylindrical portion is provided so as to penetrate a bottom surface of a case. In addition, a lid body provided on the case and an upper plate of a filter element so as to cover an upper end of the case has a first hole that communicates between a space inside the case and a space outside the case. When the back pressure valve opens (a valve body does not abut on a first valve seat), a space inside the filter element communicates with the space outside the case via a second through-hole formed in a side surface of the cylindrical portion.

A filter unit is disclosed that increases solids loading capacity, decreases specific flowrate during filtration, and improves backwash effectiveness. A flow shaping plate and/or flow diverting member are used to reduce flow entrance effects during reverse, backwash flow through the filter unit.

A filter device for fluids has a filter housing (1), in which element receptacles (31) for a plurality of filter elements (33) are provided. The filter medium (35) of the filter elements (33) separates in the filter housing (1) a dirt side (5) from a clean side (7). The filter housing (1) can be opened for inserting and removing the filter elements (33). For the filter elements (33), a support basket (19) is provided, which can be inserted into the filter housing (1) and removed from the filter housing (1) and to which the filter elements (33) can be detachably fixed. The filter elements (33) have, in addition to the filter medium (35) for particle filtration, an adsorption medium (36).

A removable and replaceable end cap that selectively lockingly engages a seat ring of a filter housing. The end cap may include a flange that compresses a gasket member between the end cap and the seat ring to form a fluid tight seal therebetween. The end cap may include cam locking grooves that may each receive insertion of a protrusion of the seat ring, and which are structured for at least rotational displacement about the received protrusion as the end cap is rotated between locked and unlocked positions relative to the seat ring. The end cap may also include an opening that accommodates the passage of a fluid to a filter element. The filter element, which may be coupled to the end cap, may be adapted to remove particulate or contaminate from the received fluid.

A filter support element for a candle filter is provided. Methods of making and using the filter support element are provided.

An apparatus for filtering fluid has a container, a platform positioned in the interior volume of the container in a location above a bottom of the container, and a bag filter extending through a hole in the platform. The bag filter has an inlet and an outlet. The inlet is positioned at or above a top surface of the platform and an outlet positioned below the top surface of the platform such that a fluid passing through the fluid inlet of the container flows into the inlet of the bag filter and outwardly of the outlet of the bag filter so as to flow toward the fluid outlet of the container. A retainer plate is positioned over the platform and has an orifice opening to the inlet of the bag filter.

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.
