Water quality assessment sensor, water quality assessment method for feed water using water quality assessment sensor, and operation management method for water treatment facility

摘要

The same phenomenon as the phenomenon that a component of feed water is adsorbed to the surface of the membrane is used to assess water quality. Specifically, a sensor whose surface has a thin layer made of the same material as the material of the surface of the membrane and which includes a measurement unit such as a quartz crystal sensor that measures an adsorption rate on the thin layer is used to assess an effect of the water quality of the feed water on the membrane on the basis of a change in the adsorption rate on the sensor surface.
