摘要： Embodiments of the present invention provide surface mount filters including low-profile surface mount filters. One embodiment of the present invention includes a filter housing adapted to mount on a substrate block having a plurality of flow paths and a filter cavity defined therein. The filter cavity is defined to extend in a generally horizontal direction when the low-profile filter is in use. A first flow passage is defined to connect an inlet of the filter housing to a first section of the filter cavity and a second flow passage is defined to connect a second section of the filter cavity to an outlet of the filter housing. A filter assembly is disposed in the filter cavity and sealed to the surface of the filter cavity separating the filter cavity into adjacent sections including the first section of the filter cavity and second section of the filter cavity.

摘要： A multilayer porous membrane formed of an extrudable polymer is provided. The membrane is formed by co-extruding at least two compositions, each of which comprises a heated porogen and polymer while in contact with each other under conditions to minimize or prevent unstable interfacial flow between extruded layers. In a preferred embodiment, the two compositions are different such that the layers have a different average pore size.

摘要： Disclosed is a shell side contactor which can be used to form ozonated water. The contactor includes a shell and a plurality of porous perfluoroalkoxy resin thermoplastic hollow fibers that are potted at each end of the shell. The perfluoroalkoxy resin hollow fibers can be unskinned, skinned on their inner surface, or skinned on their outer surfaces. The contactor is provided with a spacer that spreads the hollow fibers adjacent an inlet to the shell, thereby permitting liquid flow at desirably high flow rates with acceptable pressure drop through the shell. The mass transfer efficiency of the contactor can be enhanced by jetting water into the fiber bundle and introducing gaps into the bundle.
