An object of the present invention is to provide a separation membrane module in which an end member is prevented from coming out even at the occurrence of a reverse pressure or the like. The invention relates to a separation membrane module which is equipped with a cylinder-shaped housing and a tubular separation membrane and which takes out a fluid which has permeated the tubular separation membrane. An end pipe is connected to one end portion of the tubular separation membrane; the end pipe is supported by a support plate which is disposed so as to traverse the housing; and an end plug is connected to the other end portion of the tubular separation membrane. The separation membrane module is further equipped with a coming-out preventive member.

A filter device includes an inlet manifold, an outlet manifold and membrane filter units. Each membrane filter unit has an inlet opening for a fluid flow to be processed, a first outlet opening for a retentate portion of the fluid flow, and a second outlet opening for a remaining portion of the fluid flow. Each inlet opening is fluidly connected to the inlet manifold, and each first outlet opening is fluidly connected to the outlet manifold. The two membrane filter units are staggered and are not axially aligned with respect to each other. One of the membrane filter units is fluidly connected to the inlet manifold and to the outlet manifold via a first set of conduits, and the other membrane filter unit is fluidly connected to the inlet manifold and to the outlet manifold via a second set of conduits.

Provided herein are tubular membrane filter elements, tangential flow filtration systems comprising such filter elements and methods of using such filter elements and filtration systems.

A water treatment system includes a coagulating and flocculating system, an ultrafiltration membrane, and a fluid driver. The coagulating and flocculating system includes a first inlet for receiving water and a second inlet configured to receive a coagulating and flocculating agent. The coagulating and flocculating system is configured to precipitate dissolved phosphorous from the water, and to provide a flocculated effluent at an outlet of the coagulating and flocculating system. The ultrafiltration membrane includes an inlet that is fluidly coupled to an outlet of the coagulating and flocculating system. The ultrafiltration membrane is configured to separate the precipitated phosphorus from the flocculated effluent. The fluid driver is adapted to transfer the flocculated effluent from the outlet of the coagulating and flocculating system to the inlet of the ultrafiltration membrane at sustained flux rates of at least 150 LMH.

Provided herein are tubular membrane filter elements, tangential flow filtration systems comprising such filter elements and methods of using such filter elements and filtration systems.

A device for mass transfer between blood and at least one gas/gas mixture, includes first and second chambers through which blood is able to flow and in each of which a respective plurality of mass-permeable hollow fibers are disposed around a respective axially extending core element, wherein a gas/gas mixture is able to flow through, and blood is able to flow around, the hollow fibers, wherein the second chamber follows the first chamber in the blood flow direction, wherein the first and second chambers are disposed next to one another, and in particular disposed spaced apart between the core element center axes thereof, and the two chambers have a connection in an axial end region by which the chamber volumes through which blood is able to flow are connected, and in particular are connected in the direction of the spacing.

An oxygen removal system for removing dissolved oxygen from fuel within a fuel system includes a first housing, a second housing, a membrane filter, a piston assembly, and an outlet cap. The first housing extends along a first axis between a first housing first end and a first housing second end. The second housing is disposed about the first housing. The membrane filter is disposed between the first housing and the second housing. The piston assembly has a piston housing that is disposed about the second housing. The piston assembly is arranged to generate a vacuum to remove a fluid from the membrane filter.

The process of producing concentrated maple sap can include concentrating the maple sap using membrane filtration to a sugar content of approximately 30? Brix, circulating the maple through a maple sap passage of a membrane, wherein the membrane contains the maple sap in a vacuum cavity, and evaporating the water from the maple sap across the membrane into the cavity. The concentrated maple sap having a sugar content above 50? Brix.

A fluid degassing device includes a first housing, a second housing disposed within the first housing, a first flow circuit defined by the second housing and the first housing between a first flow circuit opening and a second flow circuit opening of the first flow circuit, and a tube bundle of selectively permeable membrane tubes disposed in the first flow circuit between the second housing and first housing. The tube bundle is disposed at least partially around a circumference of the second housing and the first flow circuit is defined between the first flow circuit opening of the first flow circuit and the second flow circuit opening such that fuel flows rotationally around the second housing through the tube bundle.
