Title
(EN) Method for validation of polymer aqueous solutions concentration and activation in water treatment applications and polymer make-up unit therefor
Abstract
(EN)

The method of quantifying and of validation of activation status of a water treatment polymer in an aqueous sample includes the following steps: supplying polymer, e.g. continuously, to the aqueous sample; monitoring electrical conductivity measurements in the aqueous sample; thoroughly mixing the aqueous sample; correlating the conductivity measurements with the polymer concentration and activation status; and suspending mixing once conductivity steady state is achieved upon the aqueous solution polymer becoming fully activated.
