Abstract

L'invention porte sur un agent floculant qui peut être utilisé de façon appropriée pour purifier l'eau d'un système d'approvisionnement en eau et d'évacuation des eaux usées ou pour purifier l'eau contenue dans un réservoir de stockage, une mare, une rivière, un lac ou similaires. L'invention porte également sur un procédé de fabrication de l'agent floculant et sur un procédé de purification d'eau au moyen de l'agent floculant. De façon spécifique, l'invention porte sur un agent floculant magnétique obtenu par liaison chimique d'un agent floculant polymère (par exemple un agent floculant de polyacide aminé) à des micro-particules magnétiques ou à un mélange d'un agent floculant polymère avec des micro-particules magnétiques, permettant ainsi d'intégrer les deux composants ensemble.
