Abstract
In the device for mounting a separation membrane element in a separation membrane module, a sealing member is constituted of a plurality of notched circular packings made of graphite, for example, each having a notched circular shape as viewed in a plan view. The plurality of notched circular packings are fitted on an upper end portion of the separation membrane element in a state where the notched circular packings are made to overlap with each other in plural stages, notched portions of the notched circular packings arranged adjacent to each other vertically are arranged at positions different from each other as viewed in a plan view, the notched circular packings in plural stages are received by the inwardly projecting annular receiving portion in the mounting hole, the notched circular packings in plural stages are pressed to the annular receiving portion by threaded engagement of the press fitting thus applying sealing.
