ABSTRACT:
A fluid separation device, utilizing tubular or flat sheet membrane materials, bounded on the membrane side of the sheet by a sheet of a porous feed spacer material, and bounded on the support side of the membrane sheet by an optional porous permeate backing material, to facilitate the flow of fluids. The layered assembly is formed into multiple pleated thin flat channels, surrounding a solid center rod mandrel, glued at the ends, wrapped with a porous sheet material, taped, and sealed into a tubular shell. The fluid to be separated flows into one end of the pleated element, and discharges from the opening at its opposite end in a concentrated form. The fluid passes through the membrane in a purified form and discharges from an opening in the side of the tubular shell.
