PROBLEM TO BE SOLVED: To provide a membrane obstructiveness evaluation method of reverse osmotic membrane feed water capable of properly evaluating membrane obstructiveness of water fed to a reverse osmotic membrane.;SOLUTION: There is provided a membrane obstructiveness evaluation method of reverse osmotic membrane feed water for evaluating membrane obstructiveness of feed water 3 fed to a reverse osmotic membrane, by measuring insoluble TEP concentration CY in feed water 3, or calculating insoluble TEP concentration percentage to evaluate membrane obstructiveness of feed water 3 based on measurement result of the insoluble TEP concentration CY or calculation result of the insoluble TEP concentration percentage. Thereby membrane obstructiveness of feed water 3 can properly be evaluated by measuring insoluble TEP concentration CY in feed water 3 or insoluble TEP concentration percentage because the insoluble TEP concentration CY and the insoluble TEP concentration percentage have high correlation with fouling of the reverse osmotic membrane. There is also provided an operation control method of a water treatment device using the membrane obstructiveness evaluation method of reverse osmotic membrane feed water.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
