ABSTRACT:
Polymer activation apparatus for activating a batch of dry polymer in dilution water includes a tank which contains the dilution water in a mixing vessel and a mixing assembly within the mixing vessel. The dilution water is circulated at a high rate through the mixing assembly to create a high shear flow condition within the mixing assembly. The polymer is introduced into the mixing assembly to disperse the polymer in the dilution water and form a slurry in the vessel without causing agglomeration of the dry polymer. After dispersion and before hydration of the polymer, the rate of circulation through the mixing assembly is reduced to create a low shear flow condition. The low shear condition is maintained as the viscosity of the solution increases.
