Abstract: Providing a method of estimating the number of microparticles such as microorganisms in a sample, performing complicated operations. The method comprises counting by constant flow the number of target microorganisms contained in the sample at a predetermined flow rate, sectioning measurement data obtained as a result of the constant flow counting into a predetermined number of sections by a predetermined unit time for a section, counting the number of sections in which microorganisms are detected and the number of sections in which they are not detected, in the predetermined number of sections; and estimating the number of microorganisms in the sample, by a statistical method from the flow rate of the sample in the constant flow counting step, the predetermined number of sections and the predetermined unit time in the sectioning step, and the number of sections in which microorganisms are detected in the counting step.

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.
