Hydrogen purification devices and their components are disclosed. In some embodiments, the devices may include at least one foil-microscreen assembly disposed between and secured to first and second end frames. The at least one foil-microscreen assembly may include at least one hydrogen-selective membrane and at least one microscreen structure including a non-porous planar sheet having a plurality of apertures forming a plurality of fluid passages. The planar sheet may include generally opposed planar surfaces configured to provide support to the permeate side. The plurality of fluid passages may extend between the opposed surfaces. The at least one hydrogen-selective membrane may be metallurgically bonded to the at least one microscreen structure. In some embodiments, the devices may include a permeate frame having at least one membrane support structure that spans at least a substantial portion of an open region and that is configured to support at least one foil-microscreen assembly.

The present disclosure relates to modular filtration cassettes for filtering liquids including, for example, liquids used in semiconductor manufacturing. A filter housing may define a filter cavity comprising an upstream portion and a downstream portion. The filter may further comprise a filter element disposed in the filter cavity. The filter element may at least partially overlap the filter inlet on a first side of the filter element. The filter element may comprise a rectangular pleated filter with a set of pleats having a first set of pleat tips on an upstream side of the filter element and a second set of pleat tips on a downstream side of the pleated filter.

Plate-and-frame membrane modules, assemblies and processes for separating components of a fluid mixture. The assemblies comprise of a pressure vessel filled with, and able to hold, pressurized fluid being processed. Lightweight membrane plate-and-frame modules are contained inside the vessel. Fluid directing conduits direct the fluid streams being processed into and out of the vessel and across the surface of the separating membrane. Because the modules are surrounded by high pressure fluid, the forces acting on the module are small. This means the modules can be made of lightweight, inexpensive materials, such as plastic. The design of the assemblies is such that it allows for modules to be easily replaced as needed. The assemblies are also designed for pressurized feed fluid separations and separation using a sweep fluid on the permeate side of the membrane. The pressure vessel can contain one or several membrane modules.

Various high performance, high efficiency filter media are provided that are cost effective and easy to manufacture. In particular, various filter media are provided having at least one layer with a waved configuration that results in an increased surface area, thereby enhancing various properties of the filter media. The filter media can be used to form a variety of filter elements for use in various applications.

Hydrogen generation assemblies, hydrogen purification devices, and their components, and methods of manufacturing those assemblies, devices, and components are disclosed. In some embodiments, the devices may include an insulation base having insulating material and at least one passage that extends through the insulating material. In some embodiments, the at least one passage may be in fluid communication with a combustion region.

The present disclosure relates to a filter module for a medical fluid delivery system capable of removing cytokine inducing substances (CIS) from a medical fluid.

The technology disclosed relates to an arrangement for membrane distillation made of at least one plate including a structure having at least one depression or cavity. A membrane is an integral/integrated part of the plate structure or is joined to surface portions of a first side of the structure of the at least one plate so that the joined membrane is substantially parallel with and is facing a relatively thin wall constituting at least some of the more central portions of the plate structure. The surface portions of the membrane are directly joined to the surface portions of the plate structure to form a compartment configured for condensing gas into liquid. Two plates may be directly joined to each other to form a compartment for a warm-liquid channel and/or two plates may be joined to each other to form a compartment for a cooling channel.
