Title:
CLUMPING METHOD AND CLUMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/006419
Kind Code:
A1
Abstract:
The present invention pertains to a method for determining the appropriate injection ratio of a coagulant injected into a starting liquid containing a suspended matter. The clumping method includes: an injection step for injecting the coagulant into the starting liquid containing suspended matter; a stirring step for flowing the starting liquid into which the coagulant has been injected into a high-speed stirrer (1), rotating the stirring vane (8) of the high-speed stirrer (1) at a rotational velocity of at least 500 min-1 to stir the starting liquid; an optical measurement step for obtaining an optical measurement value by radiating light at the stirred starting liquid; a numerical analysis step for obtaining a numerical analysis value by means of numerical analysis of the optical measurement value; and an injection ratio determination step for determining the appropriate injection ratio of the coagulant on the basis of the numerical analysis value.
