ABSTRACT:
The inventive method inverts and activates polymer, and delivers it to an output at a relatively high concentration of polymer in an electrolyte fluid, such as water. The inversion and activation results from four steps: (1) premixing polymer and a diluent, (2) blending the premixed polymer/diluent in a derated centrifugal pump, (3) recycling a portion of the blended mix, and (4) suddenly relaxing the pressure to relax the polymer in the blended polymer/diluent mixture. A secondary source of the fluid is applied at the output to the high concentration in order to dilute it to a desired level of concentration. A pilot controlled valving system controls the secondary source of the fluid and maintains a uniform dilution despite any fluctuation in the delivery of the fluid to the activating system. A sensor at the output feeds back a control signal to maintain a uniform level of polymer activity in the outflow from the system. A check valve monitoring system gives an alarm if water seeps back toward a source of polymer which is to be activated.
