Abstract: A spiral wound membrane module adapted for hyperfiltration and including at least one membrane envelope and feed spacer sheet wound about a central permeate tube to form an inlet and outlet scroll face and an outer periphery, wherein the feed spacer sheet includes: i) a feed entrance section extending along the permeate collection tube from the inlet scroll face toward the outlet scroll face, ii) a feed exit section extending along the outer periphery from the outlet scroll face toward the inlet scroll face, and iii) a central feed section located between the feed entrance section and the feed exit section; and wherein the feed entrance section has a median resistance to flow in a direction parallel to the permeate collection tube that is less than 25% of the median resistance to flow of the central feed section in a direction perpendicular to the permeate collection tube.

IPC: B01D63/10

Abstract: A filter assembly adapted for insertion into an inner chamber of a pressure vessel, wherein the assembly includes: a spiral wound membrane module including at least one membrane envelope and feed spacer sheet concentrically wound about a central permeate tube extending along an axis (X) forming an inlet scroll face and outlet scroll face and a cylindrical outer peripheral surface, and a brine seal disposed concentrically about a portion of the outer peripheral surface; characterized by the brine seal including: i) a radially extending flexible lip defining a maximum outer diameter adapted to engage the inner chamber of the pressure vessel, ii) an end cap surface covering a portion of the first scroll face, and iii) at least one opening in the end cap surface for permitting fluid to flow through the inlet scroll face and into the feed spacer sheet of the module.

Abstract: A spiral wound module assembly including: a plurality of spiral wound modules aligned within a pressure vessel with a first module located adjacent the first end and a second module located adjacent the second end, a flow plate including opposing first and second sides positioned within the pressure vessel between the first spiral wound module and the first end of the pressure vessel with the first side facing the first spiral wound module and the second side facing the first end, and wherein the flow plate includes a plurality of holes passing from the first side to the second side which create a pressure drop in fluid passing from the first spiral wound module and the closer of the feed inlet port and concentrate outlet port; and a differential pressure sensor adapted to measure differences in pressure between fluid located on the opposing sides of the flow plate.
