Abstract:
A separation element comprising:a permeable separation body comprising a membrane defining a permeate channel in fluid communication with a first side of said separation body for collecting permeate; a permeate tube extending along an axis between first and second ends and in fluid communication with said permeate channel; a retentate channel on a second side of said permeable separation body; first and second end caps disposed respectively about said first and said second ends of said permeate tube and having said permeable body there between, said end caps including a locking structure thereon adapted to releasably engage with corresponding end cap of an adjacently positioned separation element; a seal surface connected to the permeate tube, and adapted to axially compress a sealing member between said seal surface and a seal surface of an adjacently positioned separation element, wherein said seal surface comprises an annular sealing surface secured about the outer circumference of the permeate tube, and is positioned in a plane perpendicular to the permeate tube, wherein said annular sealing surface includes an annular sealing member, to prevent fluid flow between said retentate channel and said permeate channel.
