Patent number: 9718714Abstract: A separation-membrane module 1 includes an element block 2 that is formed by arranging, in parallel, a plurality of separation-membrane elements 4 that are formed by arranging a pair of separation-membranes with their respective permeate surfaces in opposition to each other and sealing the edges of the pair of the membranes; and an aeration block 3 that includes an aeration pipe 31 and that is disposed under the element block 2. In the element block 2, at least one upper spacer 8 is disposed in the upper portion of each space between the adjacent separation-membrane elements 4, and a lower spacer 9 is disposed under the upper spacer 8 in each space between the adjacent separation-membrane elements 4. And the leftmost and the rightmost separation-membrane elements 4 of the plurality of the separation-membrane elements 4 are secured to a frame 12 at the lower spacers 9.Type: GrantFiled: November 14, 2013Date of Patent: August 1, 2017Assignee: Toray Industries, Inc.Inventors: Hideaki Ando, Yoshifumi Odaka, Yasuharu Watanabe

Publication number: 20150329381Abstract: A separation membrane module has an element unit. The element unit includes: a shaft; a plurality of separation membrane elements each including a separation membrane pair having two separation membranes disposed so that permeate-side surfaces of the separation membranes face each other and a water collecting flow path provided between the separation membranes, and a sealed portion that seals the separation membranes at peripheral edge portions of the separation membranes; a suspension portion that suspends the separation membrane elements on the shaft; and a water collection nozzle provides communication between the water collection flow path and an outside of the separation membrane elements.Type: ApplicationFiled: July 8, 2013Publication date: November 19, 2015Applicant: TORAY INDUSTRIES, INC.Inventors: Atsushi Kitanaka, Yasuharu Watanabe, Shuji Furuno, Yoshifumi Odaka, Seiko Kantani, Hideaki Ando

Patent number: 8388848Abstract: A liquid separation device is provided, and is capable of suppressing the lowering of filtration function due to an increase in flow channel resistance of permeated liquid which results in a separation membrane falling in a groove of a permeated liquid flow channel material along with accompanied breakage of the separation membrane surface. A permeated liquid flow channel material is disposed on the back side of a separation membrane composed of a sheet-like material having a linear groove and a linear crest alternately arrayed on one surface or both surfaces, wherein a groove width of the linear groove in the sheet-like material is 10 to 200 ?m, and a ratio of the groove width of the linear groove to the pitch of the linear groove is 0.45 or more.Type: GrantFiled: March 31, 2007Date of Patent: March 5, 2013Assignee: Toray Industries, Inc.Inventors: Yoshifumi Odaka, Toshimasa Katayama, Tsunemitsu Kitagawa

Publication number: 20100000935Abstract: Provided are membrane elements and membrane units capable of easily forming a space part surrounded with a frame body above the membrane elements regardless of the number of the membrane elements. That is, the membrane elements are membrane elements each comprising filtering membranes on both surfaces of a plate-like supporting plate, wherein spacer parts are formed in both side parts for keeping the membrane face distance to adjacent membrane elements being prescribed intervals, and the spacer parts have through bolt insertion holes and are extended upward from the upper end part of the supporting plate. The membrane units are configured by arranging a plurality of the membrane elements in such a manner that the channel parts formed in the spacer parts are brought into contact with each other, seal panels are installed in the outermost parts of the arranged membrane elements, and a frame body is formed by surrounding the space above the filtering membranes by the spacer parts and the seal panels.Type: ApplicationFiled: February 6, 2007Publication date: January 7, 2010Inventors: Kenji Sakai, Hiromitsu Kanamori, Yoshifumi Odaka, Toshitsugu Onoe, Hiroshi Matsumoto

Patent number: 7615105Abstract: It is an object of the present invention to provide a separation membrane in which a film-forming solution can be prevented from reaching a rear surface of a porous support in a step of forming a film, the adhesion between a functional film for separation and the porous support is high, and the thickness can be reduced. In the present invention, the separation membrane includes a porous support having a rough rear surface and a functional film for separation, and the functional film is disposed on a front surface of the porous support and extends into the porous support.Type: GrantFiled: December 9, 2002Date of Patent: November 10, 2009Assignee: Toray Industries, Inc.Inventors: Yoshifumi Odaka, Osamu Nakamatsu, Ichiro Kumo
