Scale detection device and method for concentrating device, and water reclamation processing treatment system

A scale detection device of a concentrating device, the scale detection device comprising:

• a concentrating device including a filtering membrane concentrating salt in a water to be treated containing at least calcium sulfate to obtain reclaimed water;
• a scale detection unit disposed in a branched line branched from a concentrated water line discharging concentrated water having a high concentration of salt, the scale detection unit further concentrating salt in the concentrated water to obtain reclaimed water for detection, and including a detection membrane detecting the absence or presence of scale component deposition in the concentrated water;
• and
• a circulation line that is disposed from a separation line for concentrated water for detection discharged from the scale detection to the branched line and that feeds a part of the concentrated water for detection separated at the detection membrane back to an inlet of the detection membrane.
