PROBLEM TO BE SOLVED: To provide a monitoring device of an irreversible membrane fouling substance and a coagulation control device, capable of controlling in real- time a coagulation condition of making a coagulation mass hardly causing irreversible membrane fouling, by restraining the occurrence of the irreversible membrane fouling.SOLUTION: The monitoring device comprises: a sample water condition part 3 for conducting sample water; a first fraction filter 4 arranged in an upstream side position of the sample water conduction part 3; a second fraction filter 5 arranged in a downstream side position of the sample water conduction part 3; and a measuring device 7 for measuring an irreversible membrane fouling substance quantity of a measuring object included in the sample water between the first fraction filter 4 and the second fraction filter 5, and the first fraction filter 4 separates a substance of a fraction range upper limit particle size or more and the irreversible membrane fouling substance of the fraction range upper limit particle size or less, and the second fraction filter 5 separates a substance of a fraction range lower limit particle size or less and the irreversible membrane fouling substance of the fraction range lower limit particle size or more. |
