Abstract
A new complex alkali metal-aluminium-silicate material is made that is of particular value as a coagulant or coagulant aid in the removal of solids from aqueous suspensions. The complex material is completely soluble in hydrochloric acid. It is made by mixing with high shear an aqueous solution of alkali metal silicate and an aqueous solution of an aluminium salt in such proportions and under such conditions that a complex alkali metal-aluminium-silicate polymeric material is formed substantially immediately upon contact of the solutions and is rendered into a stable dispersion in water.
