- TOC contains urea.
- the removal rate of urea is significantly different (low) from the removal rate of impurities such as other organic carbons. Therefore, the calculation of the urea removal rate may be performed separately from the calculation of the TOC removal rate. In such a calculation, it is necessary to consider the removal rate of TOC, the removal rate of urea, and the removal rate of TOC excluding urea. As an empirical value actually measured, 20% of the urea concentration may be detected as TOC. In this way, rather than calculating the removal rate using the TOC value on the inlet side and the TOC value on the outlet side of the water treatment device as they are, the removal rate of the urea component and the removal rate of other components are calculated. It is possible to obtain a more accurate TOC removal rate value by calculating each. That is, it is preferable to calculate the removal rate using the value obtained by subtracting the urea component from the TOC value on the inlet side of the water treatment device.

At this time, the warning unit 340 outputs a signal for performing a process for lowering the density. This warning may display a process for lowering the density at the same time as outputting a predetermined alert from the information processing apparatus 300. The process for lowering the concentration will be described later.
