摘要： Embodiments disclosed herein include a feed spacer for membrane separation system with an angle of less than 90 degrees, and generally less than 60 degrees; with a strand count of less than 9 by 9 per inch, and generally less than 7 by 7 per inch. Reduction in strand angle and reduction in strand count can demonstrate reductions in bio fouling, as well as prevent (or attenuate) increases in pressure drop.
