Abstract
The apparatus includes a frame in which a vessel is mounted. Water is delivered into the vessel through one inlet, polymer is delivered into the vessel through a second inlet, and a further liquid is delivered into the vessel through a further inlet. A pulsating pump delivers the polymer to the vessel and a continuously operated pump delivers the further liquid into the vessel. Either pump can be energized separately or both pumps can be energized depending upon the situation. For example, the polymer pump is energized when it is desired to deliver an emulsion polymer to the vessel and the other pump is energized when one wants to deliver a solution polymer.
