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.

Claim (Index 1):
A reverse osmosis filter module comprising:\n a tube which includes an opening that accommodates a permeable liquid in a longitudinal direction; one or more reverse osmosis membranes which extends outward from the tube and are wound around the tube; and a feed spacer which is in contact with the one or more reverse osmosis membranes and wound around the tube, wherein the feed spacer is configured such that a first set of parallel filaments and a second set of parallel filaments intersect, and one or more of the first set of filaments or one or more of the second set of filaments have an asymmetric diameter formed as partial regions of outer surfaces of the filaments protrude outward in an intersection in which the first set of filaments and the second set of filaments intersect.
