縮装置。 It consists of a reverse osmosis membrane tank incorporating a reverse osmosis membrane and equipped with a concentrated liquid supply port and a concentrated liquid outlet for the reverse osmosis membrane, a booster pump, and an energy recovery means, each of which has a reverse osmosis membrane. A first cylinder mechanism and a second cylinder mechanism each having a built-in piston are arranged concentrically in parallel, and the piston in both cylinder mechanisms is separated from the partition wall between the first cylinder mechanism and the second cylinder mechanism. A concentrated liquid pipe line from a concentrated liquid outlet in the reverse osmosis membrane tank is connected integrally with a rod that slidably passes through the cylinder chambers, and a concentrated liquid pipe line from the concentrated liquid outlet in the reverse osmosis membrane tank is connected to one cylinder chamber between the piston and the partition wall in both cylinder mechanisms. Connect each,
A first switching state in which one cylinder chamber of the first cylinder mechanism is communicated with the concentrate outlet and one cylinder chamber of the second cylinder mechanism is communicated with the concentrate discharge conduit in the concentrate pipe. and a second switching state in which one cylinder chamber in the first cylinder mechanism is communicated with the concentrate discharge pipe and one cylinder chamber in the second cylinder mechanism is communicated with the concentrate outlet. A switching valve is provided, and a concentrating liquid introduction pipe is connected to the suction port to the other cylinder chamber in both cylinder mechanisms, and a discharge port from the other cylinder chamber in the both cylinder mechanisms is connected to the opposite cylinder chamber. A reverse osmosis membrane concentration device, characterized in that the booster pump is provided in a liquid to be concentrated supply pipe line that connects a liquid to be concentrated supply port in a osmotic membrane tank.
