Abstract: Provided is a water treatment system that prevents overlook and misdetection of abnormal flocculation. The water treatment system includes a mix tank, a flocculation tank, a plurality of floc-particle-diameter measurement devices, a fault detection device that detects abnormal flocculation, and a notification device that notifies occurrence of the abnormal flocculation. The fault detection device includes: a calculator that calculates at least one of a difference and a ratio between particle diameters of floc; a storage that stores therein a tolerable range of at least one of the difference and the ratio between the particle diameters of floc; a determiner that, when the calculated value is within the tolerable range, determines that it is normal, and when the calculated value is outside the tolerable range, determines that it is abnormal; and an outputter that transmits an abnormal flocculation detection signal to the notification device.

Abstract: An information processing system comprises: an acquisition means configured to acquire vibration of a device that vibrates during operation, as time-series data of a physical quantity A indicated by a plurality of axis components in a three-dimensional coordinate system; a calculation means configured to calculate a first evaluation value E indicating a degree of bias of the vibration of the device between axes, based on the time-series data of the physical quantity A; and an estimation means configured to estimate a degradation level G of the device based on the first evaluation value E.
