A spiral-wound filtration cartridge, which renders the need for brine seals unnecessary, is disclosed. The spiral cartridges of the invention comprise a spirally-wound inner filtration assembly having an impermeable outer cylindrical surface, a housing having a cylindrical cavity formed therein for receiving the inner filtration assembly, and at least one continuous longitudinally-oriented fluid pathway disposed between the inner filtration assembly and the housing, the fluid pathway allowing for a portion of a fluid entering one end of the filtration cartridge to bypass the inner filtration assembly and proceed to the other end of the filtration cartridge. |
