A monolithic membrane filter for the filtration of liquids includes a support formed from a porous inorganic material of permeability K.sub.s, the support exhibiting a tubular shape having a main axis, an upstream base, a downstream base, a peripheral surface and an internal portion; channels parallel to the main axis of the support, formed in the internal portion of the support, the channels separated from one another by internal walls formed from the porous inorganic material; a formed in the internal portion of the support and opening onto the peripheral surface so that the filter has an external surface formed by the peripheral surface of the support and the surface of said at least one slot; and a membrane of permeability K.sub.m and of mean thickness t.sub.m covering the internal surface of the channels.

Apparatus and methods for use in water processing include housing sections that house in their interiors water treating membranes, the respective interiors being separate from one another. A distributor chamber for containing a flow of water to be treated conveys water to be treated from a feed inlet and distributes the water to be treated into the interiors of the housing sections. A collector chamber for collecting treated water from the interiors of the housing sections is provided to communicate a merged flow of the treated water to an extraction outlet. The device may be employed in subsea systems or in a topside water processing system.

The present invention relates to a tangential flow separator element for separating a fluid medium for treatment into a filtrate and a retentate, said separator element comprising a monolithic rigid porous support (2) of rectilinear structure with a plurality of channels (3) formed therein for passing a flow of the fluid medium for treatment between an inlet (6) and an outlet (7) for the retentate, in order to recover a filtrate from the outside surface (5) of the support. According to the invention, the monolithic rigid porous support (2) defines obstacles (9) to the flow of the fluid for treatment, which obstacles extend from the inside walls (31) of said channels, are identical in material and porous texture to the support, and present continuity of material and of porous texture with the support, the obstacles (9) generating variations in the flow sections of the channels.

In order to produce a tubular filter membrane element for microfiltration purposes, a plastic section of a small membrane tube is sealed at one axial end thereof and is fitted with a plastic adapter piece at the opposite end. The adapter piece is injection-molded onto the section of the small membrane tube and is preferably welded thereto. The section of the small membrane tube is sealed at the one axial end thereof by bringing this end into contact with a hot stamp.

A membrane filter includes a plurality of honeycomb ceramic filtering elements, each element including a plurality of parallel ducts separated by walls and open on a face for introduction of the liquid to be filtered, an interstitial volume between the filtering elements, a filtration membrane positioned on the inner surface of the walls of the ducts, wherein the filtering elements are joined together by a curable material that forms after curing a sleeve in the form of a single part joining together, by sealing, all of the filtering elements separated the interstitial volume, the sleeve having a thickness e between 1% and 10% of the length of the filter, and the curable material being present in the open porosity and through the entire thickness of each porous wall forming the elements, over a minimum non-zero height h.

The present invention relates to a permeate tube member correction device used to improve the quality of permeate tube members and prevent deformation issues. The device comprises two fixed supports, one connected to a rotating shaft and the other mounted with a fixed plate. A hollow mandrel is rotated, causing a correction roller to roll along the inner wall of the permeate tube member, correcting its roundness and straightness. This prevents deformation caused by weight-induced cooling during production, ensuring better subsequent processing, installation, and use. Multiple correction rollers are inserted into the permeate tube member and expanded to contact its inner wall. This correction method applies circumferential rotation force, avoiding axial deformation caused by contact friction between the correction rollers and the inner wall when they enter the permeate tube member.

Embodiments described herein are directed to methods of manufacturing a multi-leaf membrane module for filtering product fluid flow (e.g., food products or wastewater) and such multi-leaf membrane modules. In an embodiment, a multi-leaf membrane module is disclosed. The multi-leaf membrane module includes a permeate fluid flow tube defining a permeate fluid flow channel for permeate, and a membrane sheet spirally wound about the permeate fluid flow tube.
