Abstract

Disclosed are seamless membrane bags, for example, a membrane bag comprising a spacer fabric and a volume for permeate collection, the spacer fabric comprising a first part and a second part that are spaced apart and tied together at a predefined distance by monofilament thread and the first and second parts are at least partially embedded with membrane substance and the volume for permeate collection is interposed between the first and second parts. The membrane substance embeds portions of the monofilament thread and fills the spacer fabric along the border of the membrane bag. The membrane substance completely enclosing the volume is seamless. Also disclosed are processes for producing such bags, a filtration unit comprising such a membrane bag, and their uses in the separation of fluids, vapors and particles.
