摘要： A polymer activation apparatus for activating and diluting a liquid polymer with water includes, a vessel defining a cylindrical chamber divided into first and second processing zones, the polymer and water being supplied to the first processing zone, an impeller located in the first processing zone subjecting the polymer to a high shear rate for a short contact time to initiate dissolution and activation of the polymer, and the polymer being moved to the second processing zone under the force of the water supplied to the first processing zone, a second impeller in the second processing zone subjecting the polymer to a lower shear rate for a longer period to continue the polymer dissolution and activation process.
