Abstract
A reverse osmosis system including a proportioning flow control, for controlling brine flow from a pressure resistant vessel containing a membrane cartridge, which has ends of two small diameter duct portions enclosed inside a hollow body, which is separate from the pressure resistant vessel containing the membrane cartridge. Means, such as a unitary mass of solidified epoxy adhesive, seals the passage of each of the duct portions through a wall of the hollow body and leaves space within the hollow body with which the open ends of the small diameter duct portions communicate and which itself communicates with a relief valve connected to a collector or tank for storage of permeate from the membrane cartridge under elevated pressure.
