(FR) PROCÉDÉ DE VALIDATION DE CONCENTRATION ET D'ACTIVATION DE SOLUTIONS AQUEUSES POLYMÈRES DANS DES APPLICATIONS DE TRAITEMENT DE L'EAU, ET UNITÉ DE PRÉPARATION POLYMÈRE ASSOCIÉE
Abstract
(EN)
The method of quantifying and of validation of activation status of a water treatment polymer in an aqueous sample comprises the following steps: continuously supplying activated polymer 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 supply to the aqueous solution of the polymer once conductivity steady state is achieved upon the aqueous solution polymer becoming fully activated.

(FR)
L'invention concerne un procédé de quantification et de validation d'état d'activation d'un polymère de traitement de l'eau dans un échantillon aqueux, qui comprend les étapes suivantes : fournir en continu un polymère activé à l'échantillon aqueux; surveiller les mesures de conductivité électrique dans l'échantillon aqueux; mélanger soigneusement l'échantillon aqueux; corréler les mesures de conductivité avec l'état de concentration et d'activation en polymère; et suspendre l'alimentation de la solution aqueuse du polymère une fois l'état régulier de conductivité réalisé et le polymère de la solution aqueuse devenant complètement activé.
