Abstract

DESALINATION SYSTEM A desalination system includes: a pressurized vessel which generates concentrate water and permeate water by causing treatment 5 target water to pass through a reverse osmosis membrane element built in the pressurized vessel; an energy recovery device which is located on a discharge channel so as to discharge the permeate water, and recovers energy of the permeate water; a bypass discharge channel which branches off from the discharge channel and is located between 10 the pressurized vessel and the energy recovery device, and which discharges the permeate water; and a bypass control mechanism which is located on the bypass discharge channel and controls a discharge volume of the permeate water. 15 [Figure 1]
