In a water tank 1 such as a bathtub or a swimming pool, a circulation pump 3 having a turbidity sensor 2 installed upstream and a filtration tank 4 are connected by pipes. Filtration tank 4
A channel switching valve 5 is built in, and a occupant counter 6 is installed near the water tank. Then, the turbidity sensor 2, the circulation pump 3, the flow path switching valve 5 and the occupant counter 6 are electrically connected to a drive control device 7 having a variable speed means 8 such as an inverter.

た最少使用人数相当の周波数で運転する。The circulation pump 3 starts its operation manually by an operator or according to a setting condition of a timer (not shown). At this time, when the signal from the turbidity sensor 2 is equal to or higher than a predetermined value, the circulation pump 3 operates at maximum capacity. If the signal from the sensor 2 is less than the predetermined value, the operation is performed at a preset frequency corresponding to the minimum number of users.
