The at least one seal plate can seal one end of the cartridge. The seal plate can have at least one venting hole that forms a passage between the interior of the cartridge and the outer groove. The sealing ring can have a cross-sectional shape that forms a circular venting path between the sealing ring and the seal plate. The sealing ring can include one or more grooves to allow fluid to vent into an annular space between a device housing and the membrane separation unit. The sealing ring can include an outer surface having, in cross-section, two flattened surfaces that form an angle of between 90° and 175° there between.
