    • PROBLEM TO BE SOLVED: To solve the problems of the membrane element of a membrane separation apparatus for treating sewage, wherein the membrane element is liable to cause vibration as it is subjected to aeration in a treatment tank, stress concentration is caused by the vibration, causing cracks in particular at the liquid collection part of a support, to cause defect in durability. SOLUTION: The membrane element 10 includes a separation membrane 41 and the support 31 supporting the membrane element and having a nozzle hole 33 leading out filtrate. The support 31 includes the liquid collection part 34 penetrating through in the front/rear direction, the liquid collection part 34 includes a roughly T-shape with round ends of respective sides, and is communicated with the nozzle hole 33 at the upper plane of a horizontal side H of the roughly T-shape. This configuration prevents the stress concentration by vibration deforming, to eliminate breakage of the membrane element. COPYRIGHT: (C)2009,JPO&INPIT
