Abstract: A contactor module for a contactor panel includes a frame member and a contactor media coupled to the frame member. The contractor module defines a first side and a second side. The contactor media includes at least one first membrane array including a plurality of first hollow fibers extending along a first fiber axis. The at least one first membrane array defines a first axis. Further, the contactor module includes at least one second membrane array including a plurality of second hollow fibers extending along a second fiber axis. The at least one second membrane array defines a second axis. The at least one first membrane array and the at least one second membrane array is disposed such that a first inclination angle is defined between the first axis and the second axis. Moreover, the first inclination angle is greater than zero degree and less than 180 degrees.

Abstract: A membrane contactor includes: a cap has an internally beveled surface and a cap port; a cup body has an externally beveled surface in sealing engagement with the internally beveled surface, a side port on a side of the cup body and an end port located on an end of the cup body; and a membrane cartridge is located within the cup body, is sealed to an open end of the cup body, and is in sealed fluid communication with the end port. A method of making a membrane contactor includes the steps of: sealingly mating a perforated center of a membrane contactor with the end port of a cup body; sealingly joining an end of the membrane cartridge adjacent an open end of the cup body; and sealingly joining a beveled surface of the cap to a beveled external surface of the cup body.

Abstract: A contactor system includes a plurality of contactor panels. Each contactor panel includes a frame member and a membrane array adapted to be received within the frame member. The membrane array defines a first end portion, a second end portion, and a plurality of hollow fibers. The contactor system also includes a first manifold in selective fluid communication with the first end portion of the membrane array of each contactor panel. The contactor system further includes a second manifold in direct fluid communication with the second end portion of the membrane array of each contactor panel. The contactor system includes a controller configured to provide selective fluid communication between the first manifold and the first end portion of the membrane array of each contactor panel.
