Abstract
Procédé pour épurer les milieux aqueux pollués par floculation. On utilise à cet effet un produit obtenu par dissolution d'un liguine-sulfonate dans l'eau, mélange avec un sel de cérium et addition de sulfate d'aluminium. On ajoute ce produit à l'eau polluée à épurer et on agite, de préférence à l'air. Le procédé selon l'invention permet d'obtenir des eaux épurées qui, dans certains cas, sont potables directement.
