Abstract

L'invention concerne un procédé d'obtention d'un produit coagulant. De façon caractéristique, on prépare une matière première contenant de la boue résultant du traitement d'eau potable et un minerai contenant du fer et/ou de l'aluminium, cette matière première étant soumise à une attaque acide en vue de former des sels de fer, des sels d'aluminium ou de leur mélange. Application de ce coagulant lors de la réalisation d'une étape physico-chimique du traitement des eaux usées et /ou industrielles.
