Embodiment Construction
[0097] figure 1 An exemplary embodiment of a membrane filter assembly 10 configured for use in a membrane filtration system (not shown) is shown. Assembly 10 may include one or more membrane rows 12 which may be arranged adjacent to each other in a frame 14 to form assembly 10 . A single membrane row 12, such as figure 2 and image 3As shown, a header 16 may be included having one or more bundles 18 of hollow fiber membranes attached to one or more bundle bodies 20 of the header 16 . The hollow fiber membrane bundle 18 may include a plurality of hollow fiber membranes 32 and is also referred to herein as a fiber bundle. Each hollow fiber membrane 32 may include an exterior surface, a lower end fixed in header 16 and a sealed free-moving upper end suspended by liquid in a tank and adapted to float in the liquid.
[0098] A single membrane row 12 may also include a permeate riser 22 at one end and an aeration riser 24 in fluid communication with header 16 at the other end....

Abstract
A membrane filter assembly configured to treat a liquid contained in a water tank at ambient pressure is disclosed. The assembly may have a header and a membrane bundle containing a plurality of substantially vertical hollow fiber membranes, wherein a lower end of each hollow fiber membrane is secured in the header. The assembly may also have a gasification device adapted to periodically generate air bubbles and configured to release the air bubbles within the membrane bundle. The assembly may also have an enclosure substantially surrounding the membrane bundle by extending from a lower region to an upper region of the membrane bundle, and the enclosure is configured to retain the liquid introduced into the enclosure so that the liquid surrounds the membrane bundle. Each bubble has a cross-sectional area corresponding to a cross-sectional area of the enclosure so that the cross-sectional area of the bubble occupies substantially the entire cross-sectional area of the enclosure when the bubble flows along the membrane bundle.
Description
[0001] The application date of this application is August 10, 2015, the international application number is PCT / US2015 / 044489, the Chinese national application number is 201580057378.8, and the invention name is "Membrane module system and operation using membrane bundle enclosure and pulse aeration method" application. [0002] priority claim [0003] This PCT International Application claims priority to US Provisional Application No. 62 / 067,127, filed October 22, 2014, the subject matter of which is incorporated herein by reference in its entirety. [0004] manual technical field [0005] The present disclosure relates to hollow fiber membrane filtration systems designed for submersion in contaminated water tanks using membrane bundle enclosures and pulse aeration, and methods of operation. Background technique [0006] Various membrane filtration systems have been used for many years to treat sewage, such as blowdown or waste water. These systems vary in complexity ...
