Spiral-wound membrane cartridge with ribbed and spaced carrier layer

摘要: Disclosed are spiral-wound membrane cartridge constructions for use in ultrafiltration and reverse-osmosis separation equipment, each of which include a feed layer, layer permeate carrier layer. By using the form channel material having plurality parallel ribs extending an axial direction, interconnected by matrix smaller filaments may be generally perpendicular thereto, this construction advantageously reduces resistance to liquid frlow axially through cartridge, registering only very low pressure drops. Such cartridges 40 70 inches length 8 diameter employed series, even within single outer casing or vessel. especially useful separating liquids high levels particulate contamination membranes where clogging is common problem also concentrating solutions fairly viscous water-soluble polymers.
