Abstract
The present invention relates to a membrane separation system including a plurality of separation membrane elements connected to one another, each of the separation membrane elements including a plurality of separation membrane pairs, each separation membrane pair including separation membranes each having a feed-side surface and a permeate-side surface and disposed such that the feed-side surfaces face each other, in which the plurality of separation membrane elements include a first separation membrane element and a second separation membrane element, and at least one first separation membrane element serves as a stage preceding the second separation membrane element.
