1. A filter element, comprising:
a single closed membrane structure wrapped about a core in reciprocating clockwise and counterclockwise directions forming semicircular folds of membrane about the core, the semicircular folds of membrane having opposingly situated apical ends separated by a gap, wherein the closed membrane structure has an interior portion defining at least one feed channel and an exterior portion defining at least one permeate channel, and an area defining a radial permeate discharge path, said radial permeate discharge path formed by the gap created by the opposingly situated ends of the semicircular folds of membrane and the core and/or a housing having one or more openings in fluid communication with the radial permeate discharge path.
