ABSTRACT:
A restrictor in the form of an elongated small duct or tube is employed for brine or concentrate flow control in a reverse osmosis system. The duct is composed of two portions, one end of one of these portions being connected to the brine output of a semipermeable membrane cartridge, and one end of the other of these two portions being connected to the brine disposal system. The other ends of both these duct portions communicate with the interior of a common compartment which, in turn, communicates through a pressure relief or check valve with the purified water collector of the semipermeable membrane cartridge. When the pressure in the purified water collector exceeds the pressure in the compartment, the check valve opens and purified water flows into the compartment and out through the portion of the elongated small duct or tube leading to concentrate disposal. The two portion small diameter duct or tube thereby acts as a restrictor for concentrate or brine flow control and also for controlling a check or pressure relief valve for pressure control in the purified water collection and storage system.
