  • Publication number: 20230338899
    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.

  • Publication number: 20230182081
    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.

  • Patent number: 10744265
    Abstract: A container is provided. The container includes a body, a first plug, and a second plug. The body has a first end, a second end, and a bypass with a length L disposed between the ends. The first and second plugs are slideably disposed in the body and define a first compartment. A second compartment is in the body between the second plug and the second end. The second plug has a first edge; a second edge; and a plurality of primary conduits, each primary conduit extending from first openings in the side wall to second openings in the bottom surface. The bottom surface does not define a plane oriented substantially orthogonal to the longitudinal axis. A distance D extends longitudinally from the first edge to the second edge. A distance E extends longitudinally from the first edge to the first opening. D?L and E<L.

  • Patent number: 10507286
    Abstract: A container and methods for storing and mixing a two-component composition is provided. The container includes a body, a first plug and a second plug. The body has a first end, a second end, and a bypass with a length L disposed between the first and second ends. The first and second plugs are slidably disposed in the body and define a first compartment. A second compartment is disposed in the body between the second plug and the second end. The second plug has a first edge, a second edge, and a plurality of spaced-apart primary conduits extending through the second plug. Each primary conduit has a separate first opening. A distance D extends longitudinally from the first edge to the second edge and a distance E extends longitudinally from the first edge to the first opening that is nearest the first edge. D?L and E<L.
