The filter element generally includes a closed membrane structure (510) wrapped about a core (530) in reciprocating clockwise and counterclockwise directions, forming semicircular folds of membrane about the core. The semicircular folds of membrane have opposingly situated apical ends (560) separated by a gap. The interior of the closed membrane structure (510) defines a feed channel and the exterior of the closed membrane structure defines at least one permeate channel (522). A radial permeate discharge path (550) extends through the gap between the apical ends of the semicircular folds of membrane. Systems containing, and methods of using, filter elements including radial permeate discharge paths are also provided.
