In the turbidity sensor 25, the light emitting unit 252 and the light receiving unit 254 are installed on, for example, the inner wall of the immersion tank 8. In consideration of the fluidity of the processing liquid 16, an interval is set between the light emitting unit 252 and the light receiving unit 254 so that the processing liquid 16 can flow. A light source composed of a light emitting element such as an LED (Light Emitting Diode) is installed in the light emitting unit 252. A light receiving element such as a light receiving transistor that produces an output according to the amount of light received is installed in the light receiving unit 254.
The detection unit 256 causes the light emitting unit 252 to emit light at a fixed timing, passes through the processing liquid 16, or receives the light 253 scattered by the processing liquid 16 by the light receiving unit 254. The light receiving signal generated by the light receiving unit 254 is acquired by the detection unit 256.

In FIG. 5, B has time (t) on the horizontal axis, turbidity Tu and turbidity signal Rp on the vertical axis, and shows the time transition of turbidity Tu and turbidity signal Rp.
As a result of the object 14 to be cleaned being immersed in the treatment liquid 16 periodically or irregularly, the turbidity Tu increases with the passage of time, and the amount of light received by the light receiving unit 254 decreases. As a result, the level of the turbidity signal Rp tends to decrease as opposed to the increase in turbidity Tu. Therefore, the control unit 26 can acquire the transition information Tui of the turbidity Tu from the turbidity signal Rp.

<Pretreatment for cleaning the object to be cleaned 14>
As shown in A of FIG. 7, the object to be cleaned 14 is delivered from the object waiting unit 12 to the conveyor unit 18 on the immersion tank 8 side by the conveyor unit 56.
As shown in B of FIG. 7, the object to be cleaned 14 is immersed in the treatment liquid 16 by lowering the elevating mechanism 20. After being immersed for a predetermined time, the object to be cleaned 14 is pulled up from the processing liquid 16 by the ascent of the elevating mechanism 20 as shown by the broken line, and is passed from the immersion tank 8 to the washing machine 4 by the conveyor unit 18.
When the object to be cleaned 14 is immersed in the treatment liquid 16, the dirt adhering to the surface of the object to be cleaned 14 is separated into the treatment liquid 16 by the cleaning function of the treatment liquid 16, and the removed dirt suspends the treatment liquid 16. Let me.

<Relationship between turbidity Tu transition information Tui, waste amount Md of treatment liquid 16 and compensation amount Ms>
In FIG. 8, the horizontal axis represents the disposal time td of the treatment liquid 16, the vertical axis represents the turbidity Tu of the treatment liquid 16, the waste amount Md and the compensation amount Ms, and the disposal amount Md and the compensation amount are taken from the disposal time td and the transition information Tui. The increase / decrease relationship of Ms is shown.
The disposal time td1, td2, and td3 indicate the passage of time from the start of use of the treatment liquid 16. The turbidity Tu increases with the passage of time, and the transition information Tui represents the time transition of the turbidity Tu. The turbidity Tu of the disposal time td1, td2, and td3 has increased to Tu1 <Tu2 <Tu3.
From such a relationship, an increase in the turbidity Tu of the treatment liquid 16 reduces the cleaning function of removing dirt from the object to be cleaned 14. In order to restore this cleaning function, it is effective to reduce the turbidity Tu of the treatment liquid 16.

In this embodiment, the waste amount Md of the used treatment liquid 16 is calculated from the disposal time td and the turbidity Tu, the compensation amount Ms equal to the waste amount Md is set, and the used treatment liquid 16 remains. The cleaning function of the treatment liquid 16 is restored.
At the disposal time td1, the disposal amount Md1 is set according to the transition information Tui (= Tu1) of the turbidity Tu, and the compensation amount Ms1 corresponding to this is set. That is, since the turbidity Tu is low at the disposal time td1, the disposal amount Md of the used treatment liquid 16 is small, and the compensation amount Ms1 is also small.
At the disposal time td2, the disposal amount Md2 is set according to the transition information Tui (= Tu2) of the turbidity Tu, and the compensation amount Ms2 corresponding to this is set. That is, since the turbidity Tu is higher at the disposal time td2 than at the disposal time td1, the disposal amount Md2 and the compensation amount Ms2 of the used treatment liquid 16 are increasing.

Further, at the disposal time td3, the disposal amount Md3 is set according to the transition information Tui (= Tu3) of the turbidity Tu, and the compensation amount Ms3 corresponding to this is set. That is, at the disposal time td3, the turbidity Tu is higher than the disposal time td2, the cleaning function is significantly deteriorated, and it is necessary to increase the disposal amount Md3 and the compensation amount Ms3 of the used treatment liquid 16.

The control unit 26 compares the concentration information with the reference information, and generates control information for controlling the supply amounts of the raw water 13 and the treatment agent 17. In response to this control information, the treatment liquid generation unit 50 (FIG. 3) changes the mixing ratio of the raw water 13 and the treatment agent 17 to generate the treatment liquid 16 having a concentration conforming to the reference information.
The liquid level of the processing liquid 16 in the standby tank 10 is detected by the level sensor 41, and the control unit 26 acquires the level information of the processing liquid 16. Based on the acquisition of this level information, the control unit 26 controls the liquid level of the treatment liquid 16 to the standby level, and causes the standby tank 10 to wait for the treatment liquid 16.
