Apparatus for preparing a flocculant for water treatment

Abstract

An apparatus for preparing a flocculant for water treatment, comprising: (a) a storage tank for an inorganic acid aqueous solution, (b) a storage tank for a silicate aqueous solution, (c) a storage tank for a metal salt aqueous solution, (d) a collision device for preparing a silica sol by colliding the inorganic acid aqueous solution stored in the inorganic acid aqueous solution storage tank with the silicate aqueous solution stored in the silicate aqueous solution storage tank at each rate of 5 m/sec or more, (e) a stirring and aging device for aging the silica sol obtained by the collision with stirring and (f) a feeding device for feeding the metal salt aqueous solution stored in the metal salt aqueous solution storage tank in order to mix the metal salt aqueous solution with the silica sol drawn from the stirring and aging device.
