ABSTRACT:
Described is a mixing apparatus and its use in the hydration of liquid polymers. The apparatus includes two packed mixing columns, each having two reducing couplings attached thereto to form an inlet and an outlet to each column. The outlet of the first mixing column is connected to the inlet of the second mixing column via means of a reducing passageway. The apparatus also has sources of supply for liquid polymer and water connected to the inlet of the first mixing column through metering means and injection check means. The apparatus provides controlled mixing velocity during the hydration with non-shearing agitation and without a chemical buildup.
