A filter arrangement for the filtration of oil or an ATF fluid, in particular a transmission oil filter, has at least a first and a second filtration layer which are arranged spaced apart by at least one spacer in a filter housing to form at least one intermediate chamber. At least one magnet or a magnet arrangement for keeping iron particles out of the oil flow are provided between the first and the second filtration layers.

A device and method for removing debris from a process fluid are described herein. Specifically, a sanitary disc strainer includes a strainer body, a moveable guide rod assembly, moveable within the strainer body, a plurality of grooved discs stacked on the moveable guide rod assembly, and an actuator for moving the moveable guide rod assembly to compress and decompress the plurality of grooved discs.

The invention relates to a bioactive filter for the disinfection of liquids, in particular water or aqueous solutions in containers. A structure that is advantageous in terms of filter efficiency is obtained by forming a spherical or oval filter body (1), which is coated with noble metals (FIG. 1).

A flat membrane support plate includes a connection portion, a honeycomb structural portion and a support portion. The connection portion is configured to connect a diaphragm to the flat membrane support plate in a sealing manner, is arranged at a periphery of the flat membrane support plate, and is provided with at least one water outlet. The honeycomb structural portion is arranged on the flat membrane support plate in an area enclosed by the connection portion, is provided with a first flow channel for communicating with an interior of the entire honeycomb structural portion and communicating the honeycomb structural portion with the water outlet. The support portion is configured for reinforcing the honeycomb structural portion and is arranged between the honeycomb structural portion and the connection portion.

A support grid assembly for use in a vessel. The support grid assembly includes panels each including a first wall including a media-supporting screen and a second wall to be supported by the vessel wall inner surface. A manifold is coupled to the panels and is in hydraulic communication with vessel outlet. The manifold and the panels permit fluid to flow through the screen in each panel, through the panels, into the manifold, and through the manifold to the outlet of the vessel, as well as in the reverse direction. At least a portion of the first wall may slope downward toward the manifold, and at least a portion of the second wall may form a bottom surface that is curved to substantially conform to a curvature of the vessel wall inner surface. The panels may be arranged in a circular configuration extending radially from the manifold.

A fluid control device includes a support structure configured to be deployed in a borehole, and a filtration component disposed at the support structure, the filtration component including a porous medium made from a thermoplastic polymer material, the porous medium including an open cell foam. The porous medium has a porosity selected to cause the porous medium to exhibit shape memory behavior, and the porous medium is configured to be compacted from an initial shape to a compacted shape, deployed in the borehole, and subsequently expanded due to a downhole temperature to conform to a surface of the borehole.

A system and method for a vibrating paint strainer stand that enables the user to effectuate the flow of paint through a paint strainer by vibration whereby the paint strainer is positioned in a paint strainer holder on the stand such that one or more vibration motors attached on a neck opposite of the holder can provide vibration to the paint strainer.
