49 FLOCCULATION MONITORING APPARATUS, FLOCCULATION MONITORING METHOD, AND FLOCCULATION SYSTEM ABSTRACT A flocculation monitoring apparatus and a flocculation 5 monitoring method are provided, and the flocculation monitoring apparatus and the flocculation monitoring method are capable of stably measuring a flocculation state of water to be treated even when the number (density) of flocs has increased. A measurement-light applying part (laser-light applying part 10 10) applies a measurement light to a measurement region (18) in the water to be treated (8) and a scattered-light receiving part (12) receives a scattered light due to particles of the water to be treated. A measurement value arithmetic part (arithmetic circuit 48) calculates an index related to flocculation of the water 15 to be treated, by using an amplitude of a light reception signal acquired in the scattered-light receiving part.
