Abstract

La présente invention concerne le domaine des agents de floculation du type polyvinylimidazoline. L'agent de floculation selon la présente invention se présente sous la forme d'agrégats particulaires comprenant une partie en poids de polyvinylimidazoline de haut poids moléculaire et 0,05 à 1,0 partie en poids de liant siliceux insoluble dans l'eau; les agrégats précités sont notamment des granulés, des perles, des paillettes ou des comprimés. Ces agrégats présentent une solubilité améliorée par rapport au même produit à l'état pulvérulent et conduisent à une meilleure efficacité de la séparation de l'eau dans les boues.
