Abstract

L'invention concerne un procédé que l'on peut utiliser pour clarifier des courants sensiblement aqueux et pour séparer éventuellement des solides biologiques, notamment des protéines, à partir d'opérations de traitement d'aliments, ce procédé consistant à mettre en contact un courant aqueux comprenant des solides biologiques avec un colloïde minéral anionique et un polymère organique, afin de faire floculer les solides biologiques.
