Abstract
This method for determining a flocculation state is for irradiating a liquid containing particles with laser light and determining a flocculation state of the particles on the basis of a change width of received light intensity of scattered light resulting from scattering of the laser light due to the particles, and includes: a correlation acquisition step of obtaining a correlation between the particle size of the particles and the change width of received light intensity; and a determination step of determining a flocculation state of the particles on the basis of the correlation.
Claims5
A method for determining a flocculation state is a method for irradiating a liquid containing particles with laser light and determining a flocculation state of the particles based on a change width of received light intensity of scattered light resulting from scattering of the laser light due to the particles, comprising:
- a correlation acquisition step of obtaining a correlation between a particle size of the particles and the change width of received light intensity;
- and
- a determination step of determining a flocculation state of the particles based on the correlation.
A method of flocculation treatment for adding a flocculant to a liquid containing particles to flocculate the particles, comprising:
- a determination process of irradiating the liquid with laser light and determining a flocculation state of the particles based on a change width of received light intensity of scattered light resulting from scattering of the laser light due to 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, and
- the determination process comprising a correlation acquisition step of obtaining a correlation between a particle size of the particles and the change width of received light intensity, and a determination step of determining a flocculation state of the particles based on the correlation.
