PROBLEM TO BE SOLVED: To provide a method for evaluating water to be treated by measuring accurately, simply and quickly a membrane clogging degree evaluation index included in the water to be treated such as raw city water.SOLUTION: There is provided an evaluation method of membrane clogging property of water to be treated that is treated by a separation membrane. In the evaluation method of the membrane clogging property of the water to be treated, after measuring a nanoparticle number concentration in the water to be treated, the membrane clogging property of the water to be treated is evaluated from a relation between the nanoparticle number concentration determined beforehand and a membrane clogging degree evaluation index.SELECTED DRAWING: Figure 1 |
