Abstract

There is disclosed a spiral-wound membrane module (Fig. 3) design for various membrane filtration techniques having significantly reduced fluid flow resistance in the feed stream path. Specially, the inventive spiral-wound membrane module is designed having a corrugated entrance and exit spacers (Fig. 4) together over less than 10 % of the length of the spiral wound module and stiffener sheet (Fig. 1) wound to provide for uniform feed channel gap width.
