Abstract
Provided is a feed spacer having a three-layer structure, in which a set forming the feed spacer is formed in a three-layer structure, so that the set, which is in contact with a reverse osmosis membrane, convects raw water to a center of the structure of the feed spacer and a laminar flow velocity gradient is generated at the center to decrease a polarization phenomenon of a reverse osmosis filter module and minimize pressure loss, and a reverse osmosis membrane filter module including the feed spacer.
