<p>A system for blending polymers and other chemicals in an aqueous liquid is provided. Static mixers and tubes, preferably in one or more tube bundles (20), provide a volume sufficient to allow a residence time in the system to hydrate a polymer. Static mixers may be integrated with a tube bundle. The system may be mounted on a portable base such as a trailer (60). The concentration of polymer and chemicals in water may be controlled by a controller. A variable speed electric pump (61) may be utilized to precisely control the amount of polymers or other chemicals added to the aqueous liquid.</p> |
