Document Type and Number:
WIPO Patent Application WO/2019/078604
Kind Code:
A1
Abstract:
The present invention relates to a feed spacer and, more specifically, to: a feed spacer having a three-layered structure, wherein a set constituting the feed spacer is formed in a three-layered structure such that the set coming in contact with a reverse osmosis membrane allows raw water to flow to the center of a feed spacer structure, and a laminar flow velocity gradient is formed at the center thereof so as to reduce the polarization of a reverse osmosis filter module and enable a pressure loss to be minimized; and the reverse osmosis membrane filter module including the same.
