摘要: An improvement in a membrane cartridge for insertion into a pressure-resistant container and having a central passageway holding a permeate collection tube. A cartridge is formed, at least in part, by a spiral winding of a laminate leaf comprising semipermeable membrane sheet material, permeate transfer sheet material, and porous grid sheet material. An extension on the leaf of the porous grid material is of sufficient length to encompass the circumference of the cartridge when the cartridge is positioned inside the container. The cartridge may have an outer wrapping of water-soluble sheet material.
