The spiral-wound membrane module offers users of industrial-scale reverse osmosis an economical combination of low cost, high membrane area density, and favorable mass transfer. The module combines flat-sheet reverse osmosis membrane with spacer materials for conveying feed and permeate, engineered components for sealing and isolating the fluid streams, and structural members to protect the membrane and maintain integrity in severe environments. Considerations relevant to the design of commercial modules are reviewed on a component-by-component basis, drawing upon fundamental engineering principles and representative works from the scientific and applied literature. Future directions in module design and recent developments related to large-diameter modules are also discussed.
