In step 400 of FIG. 3, the controller 100 checks whether a floc measurement time has come. When the floc measurement time is reached, the flow proceeds to step 410 to operate the first and second pumps 51 and 52 to take in the raw water, to inject a predetermined amount of flocculant from the raw water, and then to the instantaneous mixing device 130 Perform mixing.

In step 420, the control unit 100 operates the injection valve 70 to inject mixed water into the jaw 81 at 9 o'clock shown in FIG. 2, and then operates the rotary motor 60 to operate the rotary plate 140. It rotates by 30 degrees and rotates the first impeller 91 by the operation of the first motor 61 so that a floc is generated.

Next, the controller 100 proceeds to step 430 to check whether the injection of the mixed water into the first to eighth jars 81 to 88 is completed. If the injection of the mixed water into the first to eighth (81 ~ 88) is not completed, return to step 410 to repeat the above operation. At this time, the amount of flocculant injected is changed little by little. On the other hand, the residual amount injected into the first jar 81 and remaining in the instant admixture 130 is discharged before the next flocculant is added.

As described above, when the injection of the mixed water into the first to eighth chairs 81 to 88 is completed while rotating the rotating plate 140, the controller 100 controls the first to eighth portions for a predetermined time until a floc is generated. When the eighth impellers 91 to 98 are rotated and the floc generation is completed, the operation of the first to eighth impellers 91 to 98 is stopped, and the floc is measured by controlling the camera 120 and the illumination 121. When the measurement of the floc is completed, the rotating plate 140 is rotated 30 °, and the condensed water of the eighth jaw 88 which has been photographed is discharged to the discharge tank 150 at the washing point by the eighth valve 78.

When discharge is completed, the washing valve 79 is operated to wash the eighth jar 88 with raw water.

As described above, by first rotating the rotary plate 140, the flocculant is injected into the flocculant, and the flocculant is injected into the flocculant. As the floc is measured by rotating the rotating plate 140 as described above, the amount of flocculant is changed to other second to eighth jars 82 to 88 while the floc is generated by injecting mixed water into the first jar 81. By injecting mixed water to perform the test continuously, there is an advantage that can reduce the test time.

In the above-described step, floc is measured by varying the amount of flocculant injected into each of the first to eighth jaws 81 to 88 as an operation for determining the amount of flocculant injected. It is for the continuous testing of enemies during the process.

In step 450, the controller 100 checks whether the measurement time has come. If the measurement time is reached, the process proceeds to step 460 to perform the monitoring mode operation, the operation of the monitoring mode is as follows.
