Abstract

The present invention relates to a reverse osmosis filter module including an improved feed spacer, and particularly, to a reverse osmosis filter module including an improved feed spacer which has an asymmetric diameter in an intersection in which a first set of filaments and a second set of filaments intersect, thereby reducing differential pressure by increasing a cross-sectional area of a flow path, and mitigating concentration polarization by developing a swirl flow.
