Abstract
Provided is a flocculation state determination method in which a liquid containing particles is irradiated with laser light and the flocculation state of the particles is determined on the basis of the light reception intensity of scattered light that results from the laser light being scattered by the particles, wherein the flocculation state of the particles is determined on the basis of the value of a change index that indicates a change in the light reception intensity.
Claims14
A flocculation state determination method, being a method for irradiating laser light into a liquid containing particles and determining a flocculation state of the particles based on a light reception intensity of scattered light that results from the laser light being scattered by the particles, the flocculation state determination method comprising:
- determining the flocculation state of the particles based on a change index that represents a change in the light reception intensity.
A flocculation treatment method for adding a flocculant into a liquid containing particles and flocculating the particles, the flocculation treatment method comprising:
- a determination process of irradiating laser light into the liquid and determining a flocculation state of the particles based on a change index that represents a change in a light reception intensity of scattered light that results from the laser light being scattered by the particles;
- and
- a flocculant addition process of adding the flocculant in an addition amount based on the flocculation state of the particles determined in the determination process.
