ABSTRACT:
The present invention discloses a feed spacer, comprising a first layer and a second layer, for spiral-wound membrane module. The first layer consists of a plurality of first filaments, which are substantially in parallel to one another. Furthermore, the second layer also consists of a plurality of second filaments, which are substantially in parallel to one another. Moreover, the first layer is attached to the second layer, and the first filaments are disposed at an angle to the second filaments. Both the first layer and the second layer bend to the center of the spiral-wound. Additionally, the distance from the inside of the first layer to the center is bigger than that from the inside of the second layer to the center, and the diameter of the first filament is smaller than that of the second filament.
