Provided is a reverse osmosis processing device (10) provided with: a first pressurized vessel (80) that performs primary processing of water to be processed; and a second pressurized vessel (82) that performs secondary processing of water to be processed that has been processed by the primary processing. In each of the first pressurized vessel (80) and the second pressurized vessel (82), at least one reverse osmosis membrane element (22) provided with a reverse osmosis membrane (28) is disposed, a plurality of which are connected in series by a water collection tube (34) through which permeated water flows, and the number of reverse osmosis membrane elements (22) in the first pressurized vessel (80) is the same or fewer than the number of reverse osmosis membrane elements (22) in the second pressurized vessel (82). As a result, it is possible to easily replace reverse osmosis membrane elements.
Description
technical field [0001] The present invention relates to a reverse osmosis treatment device, and particularly relates to a reverse osmosis treatment device capable of easily replacing elements. Background technique [0002] In a desalination treatment device using a reverse osmosis membrane (hereinafter referred to as RO (Reverse Osmosis) membrane), in order to utilize reverse osmosis pressure, such as Figure 8 As shown, a plurality of RO membrane elements 222 are arranged in series in a cylindrical pressurized container 224 , and each RO membrane element 222 is connected by a water collection pipe 234 located in the center of the RO membrane elements 222 . Water is supplied from one side of the desalination treatment apparatus by a high-pressure pump, and the inside of the pressure vessel 224 is pressurized according to the opening degree of a valve provided on the concentrated water side. When the pressurized pressure exceeds the osmotic pressure of the supplied water, des...
