Abstract
A semipermeable membrane cartridge is reciprocated within a pressure resistant vessel to provide improved liquid flow and turbulence over the semipermeable membrane surfaces. The end of the semipermeable membrane cartridge exposed to the pressure of feed liquid introduced into one end of the pressure resistant vessel is adjusted or arranged to be of substantially the same effective cross sectional area as that of the end of the cartridge exposed to the pressure of brine being released from the other end of the pressure resistant vessel. This essentially balances the liquid pressure forces on the ends of the semipermeable membrane cartridge to provide improved conditions for reciprocation.
