Abstract
Equipment for preparing a polymer solution of a non-ionic, cationic, anionic or amphoteric polymer by reaction between a compound including at least one aldehyde function and at least one base polymer aqueous solution having at least one non-ionic monomer includes a reactor provided with a stirring system, as well as a recirculation loop including between the outlet of the reactor and the inlet of the reactor, a recirculation pump, a pH measuring probe, and a pressure differential in-line measuring device in the form of a calibrated tube configured to measure the pressure difference of the polymer solution between the inlet and the outlet of the calibrated tube, the calibrated tube being branched on the recirculation loop.
