Title:
An operating method of a membrane separation device and a membrane separation device
Document Type and Number:
Japanese Patent JP6149858
Kind Code:
B2
Abstract:
The use of the separation membranes is allowed to be balanced, and a membrane separation process is allowed to be efficiently carried out while effectively preventing fouling, even if a subunit is constituted by separation membrane unit components that use spiral-wound membrane elements. A membrane separation device comprising a separation membrane unit A that comprises a separation membrane unit component 8, feed stream side lines F1 and F2, and a permeate stream line P, and a unit for feeding a stream-to-be-treated, wherein a stream-to-be-treated sealing material is provided in the perimeter of an anti-telescoping plate of the separation membrane element, wherein the separation membrane elements can be moved within a cylindrical pressure vessel substantially in either direction, wherein the separation membrane unit is configured to feed the stream-to-be-treated through one of the feed stream side lines F1 and F2 and to discharge the concentrate stream through the other of the feed stream side lines, and wherein the separation membrane unit includes a mechanism that can switch the flow between the feed stream side lines.
