More specifically, suspended matter refers to suspended matter that is not filtered when the stream water sample is filtered using filter paper with 0.1% porosity.

The method of measuring the amount of suspended solids has traditionally been measured by filtering a stream water sample, collecting the solids, drying them, and then calculating the concentration of the solids by the difference in weight before and after, and expressing the concentration in mg / L or ppm.

The sensor 172 is described above. Is electrically connected to and displays the predicted BOD value to the outside.

The behavior of suspended solids has been studied to have a pattern similar to that of BOD. Therefore, if the behavior of suspended solids is known, the behavior of BOD can be predicted in a similar form.

As shown in FIG. 6, the calculation unit 180 may predict the BOD value based on a pattern that changes according to the behavior of the amount of suspended solids in the river water. According to the real-time suspended solids amount value measured by the sensor 172, a function value for the suspended solids amount over time can be derived, and this function value corresponds to the behavior of the suspended solids amount as described above. If the value reflects the characteristics of the stream water and the weight of the state of the river, the function value, that is, the behavior of the current river water BOD value can be predicted.

According to the prediction operation of the operation unit 180 as described above, it is possible to easily predict the BOD value by using a relatively easy measurement of the amount of floating material of the infrared type without having to go through a complicated process to confirm the BOD value.
