Abstract
A mixing and dissolving system includes a tank where a polymer flocculant in a solid state is mixed with water, a liquid feed unit for feeding an aqueous solution containing the mixed polymer flocculant from the tank, one regenerative mixer comprising a casing arranged at an intermediate position of a channel for the aqueous solution discharged from the liquid feed unit, and a bladed wheel where grooves are formed in a radial pattern on an outer circumference, and is used to mix and dissolve the polymer flocculant through pressure application by rotating the bladed wheel in the casing and forming a vortex flow of the aqueous solution along an inner circumferential wall of the casing, and an adjusting unit arranged at an intermediate position of a channel for the aqueous solution that has passed through the regenerative mixer, and controls pressure on a discharge side of the regenerative mixer.
