Abstract

PURPOSE: To easily start and stop a siphon pipe, by connecting said siphon pipe for backwashing to a water tank and actuating the siphon by the water head difference obtained by discharging water from the tank, and further, sucking the water into the tank by the negative pressure of the siphon.
CONSTITUTION: Water for miscellaneous use is fed into a tank 19 to the water level A from a supplying pipe 28 by opening an automatic valve V3 and a manual valve V4. Next, water in the tank 19 is discharged rapidly through a discharging pipe 23 by closing an automatic valve V3 and a manual valve V4 by opening automatic valves V1 and V2. Consequently, the water level in the tank 19 is lowered to the level D and air in a siphon 5 is sucked into the tank 19 through a communicating pipe 20, then the siphon 5 is actuated. When the valve V2 is closed and the valve V5 is opened while keeping the valve V1 open, air in the tank 19 is sucked into the siphon 5 by the negative pressure in the upper part of the siphon 5. Accordingly, raw water in a raw water channel 2 is sucked up into the tank 19 through a suction pipe 21, and the valve V5 is closed when the raw water in the tank 19 rises up to the water level A. Further, the siphon 5 is stopped by the valve V3.
