As described above, the flow rate of the liquid to be processed discharged from the high-pressure pump 1 is Therefore, the flow rate control valve 6 generally controls the flow rate of the permeated water flow meter 9 installed in the permeated water pipe from the permeated water amount control unit 10 in order to control the permeated water amount.

- the high-pressure pump 1 is started, but it is necessary to increase the flow rate of the high-pressure pump 1 to the minimum flow rate (minimum flow) of the high-pressure pump 1 immediately after the start-up in order to prevent excessive vibration and heating damage. Therefore, the high pressure pump 1 is started by setting the flow rate control valve 6 and the flow rate control valve 8 to a predetermined opening degree in advance so as to ensure the minimum flow rate. Specifically, the initial opening degree of the flow control valve 6 is determined in consideration of the secondary pressure loss of the flow control valve 6 and the pressure loss of the flow control valve 8 when the flow control valve 8 is fully opened.
- the pressure on the input side of the flow control valve 6 depends on the flow characteristics of the high-pressure pump 1 but is higher than the rated pressure, for example, 7.0 MPa.

Therefore, the flow rate control valve 8 is closed and the discharge amount of the high pressure pump 1 maintains the minimum flow rate.
- the inlet pressure of the reverse osmosis membrane module unit 2 is increased by the flow control valve 6 being opened and the flow control valve 8 being closed.
- the reverse osmosis membrane module inlet pressure gradually increases, and when the inlet pressure of the reverse osmosis pressure module unit 2 reaches, for example, 3.0 MPa, the permeate begins to be discharged. .
- the discharge rate of the high-pressure pump 1 becomes the same as the permeate flow rate of the reverse osmosis membrane module unit 2, and thereafter the flow rate control valve 6 is gradually turned until the permeate flow rate meter 9 reaches the rated flow rate by the permeate flow rate control unit 10.

It is good to provide.
- the high-pressure pump 1 and the pressure pump 4 are vortex pumps or plunger pumps
- the flow control valve 6 and the flow control valve 8 are globe valves, cage valves, or needle valves.
- the bypassed liquid to be processed may be drained out of the system, but may be returned to the tank or the like storing the liquid to be processed and used again as the liquid to be processed.
- the inlet pressure of the reverse osmosis membrane module unit 2 is increased by the permeated water amount control unit 10 and the high pressure pump minimum flow rate control unit 12 over a set time, but the reverse osmosis membrane as shown in FIG.

- the required inlet pressure of the reverse osmosis membrane module unit 2 varies depending on the water quality and water temperature of the liquid to be treated. In normal operation, if the required pressure at the inlet to the flow rate control valve 6 is high in response to a command from the permeate flow rate control unit 10 for this change, the flow rate control valve 6 opens, and conversely to the flow rate control valve 6. When the required pressure at the inlet is low, the flow control valve 6 is adjusted so as to be in the closing direction, corresponding to the increase or decrease in the required pressure at the inlet of the reverse osmosis membrane module unit 2.
- the required pressure at the inlet of the reverse osmosis membrane module 2 is obtained by adding the discharge pressure of the high-pressure pump 1 to the discharge pressure of the supply pump 15 and taking into account the motive energy loss at the flow rate control valve 6 unless the slight pressure loss of the piping is taken into consideration. It can be obtained by subtracting the minutes.
- the required inlet pressure of the reverse osmosis membrane module 2 is 7.5 MPa.
- the flow rate control valve 6 must lose 0.5 MPa of motive energy.
- the frequency converter (inverter) 7 is installed in the supply pump 15 at this time, the output rotation speed of the supply pump 15 is adjusted by converting the supply power frequency to the supply pump 15, and the supply pump 15 By reducing the discharge pressure from the rated 1.0 MPa to 0.5 MPa, it is possible to eliminate wasteful consumption of electric power energy. By implementing this method, there is no need to waste power energy by the flow control valve 6.
- the frequency converter (inverter) 7 may be installed in the supply pump 15 for the water to be treated to suppress wasteful power energy consumption. In such a case, the flow control valve 6 and the bypass described above may be used. A starting method and an operating method using the flow control valve 5 provided in the line are effective.
