A method of cleaning a regenerative filter having a filter housing having inlet and outlet zones, a fluid path provided between the inlet and outlet zones, and 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, the method comprising draining all fluids from the filter housing, refilling the filter housing with fluid to an optimum level, and initiating a cleaning sequence of the filter housing with the fluid at the optimum level. The cleaning sequence can comprise agitating the tube sheet, initiating a pump to effectively air scour for a first predetermined amount of time, dwelling for a second predetermined amount of time, and repeating the agitating, initiating, and dwelling until a third predetermined amount of time is complete.

The present disclosure provides a method of manufacturing a filter, wherein the filter comprises a filter body formed of a porous filtration material and a plastic support structure, the method including performing a first additive manufacturing step to form an initial portion of the support structure; positioning filtration material above or on the initial portion; performing a second additive manufacturing step to form a secondary portion of the support structure such that the filtration material is between the initial and secondary portions. Additionally, the filter body can be enclosed by positioning a first portion of the filtration material to overlay a second portion of the filtration material; and connecting the first portion of the filtration material to the second portion of the filtration material to define a pocket within the filter body, the support structure configured to maintain spacing between the first and second portions of the filtration material.

A module alignment element, and a filter capsule including the module alignment element, a method of filtering fluid using the filter capsule, and a system including the filter capsule, are disclosed.

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.

The present invention relates to a suction filter unit (1) for filtering liquids. The filter unit (1) comprises: a housing element (3) with an open first side and an open opposing, second side, the housing element (3) comprising a first set of filter element supporting elements (23); a first cover (5) sealingly connected to the first side of the housing element (3); a second, different cover (7) sealingly connected to the second side of the housing element (3), the second cover (7) comprising a second set of filter element supporting elements (25); a filter unit inlet (9); a filter unit outlet; a first filter element (13) for providing a fine filtering property of the liquid; and a second filter element (21) arranged between the first filter element (13) and the inlet (9) for providing a coarse filtering property of the liquid. The second filter element (21) is clamped between the second cover and the housing element (3) by the first and second set of filter element supporting elements (23, 25).

Stormwater drain insert assemblies that reduce or remove environmental runoff during rain storms and the like are disclosed. The stormwater drain insert assemblies include a strainer basket and filter bag that capture sediment, hydrocarbons, heavy metals and other contaminants, but allow water to pass through. The stormwater drain insert assemblies include a top bib of flexible sheet material such as water-impermeable fabric surrounding and supporting the strainer basket. The strainer basket includes at least one raised overflow port extending upwardly from a top panel of the basket. The top bib has a frame that may be adjustable in size in order to fit into various sizes of catch basins, resting on the lip between the top grate and the catch basin.

A water separation element is provided with a cylindrical woven fabric screen for separating water. The woven fabric screen is made of woven fabric yarns positioned angularly relative to each other. A first annular support piece is arranged at a first end face of the woven fabric screen and is fixedly connected to a rim area of the woven fabric screen. The first annular support piece has a lateral edge facing the woven fabric screen. The woven fabric screen is flowed through in radial direction. The woven fabric yarns of the woven fabric screen are positioned, at least over sections, at an angle greater than 0 and smaller than 90 relative to the facing lateral edge of the first annular support piece. A second annular support piece is connected to the second end face. A filter element and a filter device with such a water separation element are provided.

A filter assembly includes a filter holder into which a part of the filter is insertable, and a lock mounted to the filter holder and configured to lock and release the filter to and from the filter holder. The lock includes a guide coupled to the filter holder and configured to be linearly movable to transmit a force in a direction into which the filter is inserted, a pusher configured to transmit a force in a direction opposite to the direction, into which the filter is inserted, by an elastic member, a stopper rotatably received in the pusher to be arranged between the pusher and the guide, and configured to linearly move the filter holder by being linearly moved by the guide and the pusher, and a cam configured to lock and release the filter to and from the filter holder by guiding rotation and linear movement of the stopper.
