Abstract
An apparatus and method for mixing water and a water-soluble emulsion polymer by providing the optimum amount of mixing energy required for the polymer to effectively dissolve the polymer in the water without causing the polymer molecules to shear into smaller polymer molecules. The apparatus includes a pump means, a static mixing means and a mixing chamber means. A first circulation means connects the pump means to the mixing chamber means. A second circulation means connects the pump means to the static mixing means and further connects the static mixing means the mixing chamber means. A third circulation means connects the static mixing means to the mixing chamber means. Additionally, a flow control means selectively circulates a combined stream of the water and the polymer alternatively through the first circulation means, the second circulation means or the third circulation means. The method of using this apparatus is also disclosed.
