A pressure sensor 16 for detecting the delivery pressure of the motor-driven pump 13 is disposed and the ozone gas feeder 5 and the pump 13 are actuated according to a detection signal of a predetermined pressure drop detected by the pressure sensor 16. A bypass pipe 20 is provided for connecting the inlet side of the water tank 1 directly to the outlet side of the pump 13, and a normally conducting and normally open solenoid valve 21 which closes when conducting and which opens during power outages is disposed in the bypass pipe 20.
